Installation of the Grundfos pumping station. Household pumping station Grundfos for home

Water is supplied to the dacha, to the bathhouse, to the house, to the site - from a well or a well - using a pump. But to ensure the system's performance, other components are also needed - sensors, controllers, a storage tank, etc. All this can be selected separately, or you can purchase a pumping station.

A pumping station is all the equipment for providing a house with water in an assembly. Its advantage is that it can maintain a constant pressure in the system regardless of the flow rate.

The equipment consists of a pump (type - any suitable for your conditions), a tank for storing water supply and control sensors. The comfort level of the system is largely determined by the type of tank used. It happens:

• with storage tanks;
• with hydraulic accumulators.

A storage tank is a conventional container in which the water level is controlled by a float. The level rises, the pump turns off, it goes down - it turns on. But such a system provides very low pressure. It depends on the height difference that you managed to provide. Due to the low pressure, heaters and other household appliances cannot be used. Although, if you install it high enough, you can create a height difference sufficient to take a shower. The second unpleasant detail of using such a tank is that if the float mechanism malfunctions, there is a real threat to flood the house. This problem is solved - a discharge pipe is installed, but the system is still not reliable enough.

More modern modifications of pumping stations use hydraulic accumulators. They allow you to create and maintain stable pressure. Such a system also allows you to turn on the swap less often, which prolongs the life of the equipment.

Hydraulic accumulators in pumping stations are membrane-type tanks. In it, the container is divided into two sectors by an elastic membrane. One part contains gas (initially it is under some kind of pressure), water is pumped into the second. There is also a pressure sensor. It sets the upper and lower pressure limits.

When water is pumped in, the membrane in the tank expands, compressing the gas and creating even more pressure. When the upper threshold set on the sensor is reached, the pump is switched off. At the same time, a certain pressure is also created in the water tank. If a tap is open somewhere, water is supplied with good pressure to the distribution point. The volume of water decreases, the pressure on the membrane decreases. When the lower threshold value is reached, the relay is activated, the pump is turned on, increasing it again.

This system allows you to maintain a stable pressure, no matter how many taps are open. Therefore, when installing equipment with a membrane water tank, you can use any type, as well as automatic washing machines and other household appliances that require water pressure.

How to install

Most pumps are quite noisy, so it is advisable to install stations in non-residential premises with good sound insulation. If we are talking about the supply of water to seasonal residences, then equipment can be placed near the well, only providing protection from precipitation and the sun (usually they make a small pit, which is covered with a lid). If water is needed for the house or for the bath, which they are going to come to in the winter, you will have to take care of a separate room (or an insulated pit, but such that the pump does not freeze).

When choosing a model of a pumping station for your home, pay attention to the metal from which the pump housing is made. Steel usually makes a lot of noise, but cast-iron cases dampen almost all sounds. They deliver less hassle, although they cost more. But the best option is a stainless steel case. With him, the least hassle, although he is more noisy than cast iron.

The whole system is assembled as follows: a pipe is lowered into the well or lowered. Water is supplied to the inlet of the pumping station, from there it enters the membrane tank, and then it is already diluted around the house and the site.

How to choose

Normal water supply at home, cottages or baths is possible only with the correct selection of all parameters. And you need to choose:

First of all, you need to find out if the water arrives quickly enough in the well or well. If the debit of a well or well is less than 1.7 m 3 / hour (the amount of incoming water in one hour), the required pressure cannot be provided. The equipment is designed for higher performance.

Selection of pump type

One of the most difficult and responsible stages is the choice of a pump. It must create enough pressure to raise the water to the required height. At the same time, its performance should meet the needs for water, but at the same time, it should not exceed the capacity of the well or well.

Self-priming vortex and centrifugal pumps are used in pumping stations. Both those and others can be in monoblock or console execution. But such pumps can lift water from a relatively shallow depth:

• a pump with a built-in injector will provide supply from a depth of 8-9 meters;
• normally suction from a depth of 7-8 meters.

If you need to supply water from a greater depth, you will need to use a submersible pump. They buy it, and on its basis they assemble a pumping station, the second way out is to install a unit with a remote injector.

When using a remote injector, it will be possible to raise water from a depth of about 42 meters, but the efficiency of the system is low, and the cost of electricity is much higher - in fact, two pumps work simultaneously. But sometimes it's the best way out.

A system with a submersible pump with a large depth of the well will be the best option. It is efficient and "draws" a little energy. The only caveat: submersible equipment is quite sensitive to the purity of the water. To prevent sand, silt and other foreign particles from getting inside, a special filter mesh is installed on the pump inlet pipe.

Power selection

Productivity is selected taking into account the maximum water flow. Estimate how many taps can be open at the same time, count the volume of water that leaves through them. This will be the required pump power. In general, it is better to take this parameter with a margin, since working at the limit sharply reduces the “life” of the equipment.

On average, for a family of 3-4 people, the consumption is 2-4 m 3 / hour, and the equipment is selected accordingly.

The choice of the volume of the accumulator

In general, it is desirable to install as large a tank as possible. This will ensure that the pump is turned on more rarely. After all, the less often it turns on, the longer it will serve: starting currents on the motor are destructive. On the other hand, a large hydraulic accumulator needs to be installed somewhere, and it also costs decent money. But when the power is turned off, you will have a supply of water in the system equal to the volume of your tank.

Just be careful. There are membrane expansion tanks for gas boilers. They are much cheaper, but make the water undrinkable. And they are not designed to work with liquid, so they will soon fail.

Having picked up all these components, you can start choosing a pumping station that will meet your requirements.

Connection of a pumping station

As mentioned above, the system is simple: a pipe is immersed in a well or a well (more often 32 mm polypropylene, but sometimes 40 mm - it depends on the performance of the pump). It is supplied to the entrance of the station, and from the exit it is supplied to the water supply manifold.

But everything is not so simple. We need to ensure the maintainability of the system:

• Do everything so that you can overlap unnecessary branches.
• Provide for the possibility of draining water for the winter. Since a check valve is necessarily present in the system, it is required to make the outlet a little higher.
• Install shut-off valves at the inlet and outlet of the pumping station. Having blocked them, it will be possible to remove the equipment for maintenance without any special difficulties.

Since most of the components of the system are motionless, the connection of all elements occurs with the help of American women with union nuts. Otherwise, it is very, very difficult to assemble, and then, if necessary, disassemble.

One of the connection diagrams of the pumping station is shown in the photo. The purpose of most of the elements is clear, with the exception of the "cut-off 1" and "cut-off 2" taps. They are used when filling the system during the first start-up. Here's how the process goes:

• The "cut-off 2" valve and the drain valve are open, "cut-off 1" is closed. With this position of the valves, pouring water into the corresponding inlet, we fill the lower part of the system. Part of the air then exits through the drain cock.
• Now we close the "cut-off 2" and the drain valve and turn on the pump for 5-7 seconds. After 5 seconds, open "cut-off 1". In this way, increased pressure is created in the system, which squeezes air out of the system (a couple of taps must be open).
• The second start-up cycle: the “cut-off 2” valve is open, the “cut-off 1” is closed and the drain valve is closed. Turn on the pump again for a short time.
• After 5-7 seconds of pump operation, open the “cut-off 1” valve. The system should start. If there is still a lot of air left, you can repeat the second start cycle.

In working condition, “cut-off 2” and the drain cock are closed, “cut-off 1” is open.

The second scheme for connecting the pumping station almost does not need comments. A funnel is installed here as a filling system, and the start-up begins after the water fills the entire container inside the pump. It may take several starts to squeeze all the air out of the system.

This system is interesting with a well-thought-out cleaning system: a water filter is installed on the branch that goes into the house. As a result, we have clean water in the tap without impurities.

Popular manufacturers and reviews on the operation of pumping stations

As usual, in addition to difficulties with the selection of equipment parameters, there are difficulties with choosing a brand. Sellers do not always advise what is better, often trying to sell what is more expensive. Often the only source of more or less reliable information is user reviews.

Pumping stations

These units have a cast iron body, stable legs, engine protection against overheating. They work automatically, do not require setting parameters. Three series are available with different pumps for different depths:

• RSM series - from a depth of 8 meters will raise up to 100 liters / min.
• APM series - pumps with a submersible injector for wells with a depth of more than 30 meters. Controls the operation of the pressure switch.
• The corrosion-resistant CAM series has a bronze impeller, can lift water from a depth of up to 30 meters.

The Grundfos pumping station is a product of the German company of the same name. The authority of the manufacturer is high, the demand for products is 50% of the world demand. With the consistently high quality of products, the company opens subsidiaries. Their products are adapted to the climatic features of the region. In Russia, the branch operates in Istra, the quality of Grundfos is controlled by specialists from Germany. With high reliability, the equipment is sold at an affordable price.

Model range of pumping stations of the German manufacturer

Pumping stations are used in domestic and industrial water systems:

1. Fire extinguishing pumping stations are characterized by high productivity and high pressure.
2. Grundfos domestic pumping stations are used in private homes. They are compact and quiet in operation.
3. Booster pumping stations are used in public waterways and in industry. They are called second lift stations.

Any of the listed series of equipment is presented in various designs, meets certain tasks. The manufacturer has simplified the installation of equipment as much as possible. An inexperienced summer resident can cope with the installation, guided by the maintenance instructions for the Grundfos pumping station.

Characteristics of Grundfos products

Most of all, the demand for equipment from a well-known manufacturer is in global agriculture. Here they are required for irrigation of land, to increase the pressure in systems located far from water sources. The user can choose equipment for irrigation or domestic water supply.

A feature of grundfos pumping stations is the thoughtful layout of the nodes that form a single system. The case from special steel reliably protects working body. The complex can pump water from open reservoirs, wells and wells. The MQ, JPB series are developed according to the company's technology, but are produced by subsidiaries only for their region, without the right to export.

JP Pump Series

The JP series represents centrifugal self-priming pumps, which are equipped with Grundfos JP Booster pumping stations. Complete with the pump there is a hydraulic tank with a capacity of 24-60 liters, depending on the performance. The best irrigation system is an ejector-type station that supplies water from open reservoirs and pools.

The injection system lifts water from a depth of 25 meters, while the engine is located on the surface, and the lifting mechanism is lowered into the well. At the same time, the system works almost silently.

The most famous of this series of equipment are grundfos JP Basic 3pt pumping stations. The self-priming pump with a submersible ejector has the best price-performance ratio of all household pumps from this company. High performance, 3.6 cu. m / hour, head 47 m of water. Art. and a membrane accumulator characterize the demand for equipment. During operation, the pump supplies water saturated with air, while not reducing productivity. Most often, the pump is used in private farmsteads.

The Grundfos Hydrojet JP series is extremely rugged. Anti-corrosion coating is made outside and inside. Reliable automation leads the process in an economical mode. With a long flow of water, the pump is completely switched off.

The pumps operate by creating a pressure of 5 or 6 atmospheres in the system. The station is equipped with membrane-type accumulator tanks of various capacities. The grundfos hydroijet jp5 pumping station for residential buildings is equipped with a 24 l tank. But the system keeps the parameters more evenly, in which a hydraulic accumulator with a capacity of 60 liters is installed. With a power of 0.75 kW, the pump has a head of 43 m and costs 13,800 rubles.

MQ pumps

Pumps complete with membrane tanks represent a series of stations for domestic use. The battery tank is divided by a membrane partition. Water is in one part of it, air is supplied under pressure in the other. As a result, the pressure in the water system will always be stable, and the pump is less likely to receive a command to turn on. The equipment is produced with and without a hydraulic tank.

The grundfos mq 3-45 series pumps work with a membrane storage tank. The system is pressurized up to 4.5 bar or 45 m of water. Art. It is intended for the organization of water supply of private houses. The device can be used as a booster. Productivity of the device is 3 cubic meters / hour. The system has self-priming from a depth of up to 8 meters. Pump weight 13 kg. The grundfos 3-35 pumping station, 35 meters of water column, also has similar characteristics.

For the operation of these particular pumping stations, pressure drops are critical. The equipment works stably at a voltage of 220-240 V, in other ranges the pump will fail. For the safety of the equipment, it is necessary to use a voltage stabilizer. For rare switching on, an additional storage tank is used.

Varieties of Grundfos pumping stations used in industry

The fire extinguishing station is represented by pressurized water and foam systems. The Grundfos Hydro MX pump type has more than 60 models. Equipment can be selected for different fire extinguishing systems:

• productivity - 1.1-55 kW, with an automatic start system;
• productivity - up to 120 cubic meters / hour;
• pressure - 145 m.

Pumping stations "Grunfos", capable of supplying foam, are the main tool in fire extinguishing installations. Such systems are expensive, from 882 thousand rubles.

Grundfos Hydro booster stations represent a new type of equipment. Stations serve to raise the pressure in the water supply system. In public utilities, Grundfos Hydro 2000 pumping stations are in demand. The station is small-sized, operates in automatic mode, turning on when the pressure in the system decreases. The compact unit has technical characteristics:

• productivity - 600 cubic meters. m / hour;
• head - 144 m;
• maximum temperature of the agent - +70 0 C;
• working pressure - 16 bar.

The pump can be installed in the heating system.

The manufacturer supplies not only surface equipment, but also submersible pumping stations. Their cost is much higher, but the systems are the most reliable in operation.

Reading 7 min.

The water supply system in private houses and summer cottages is equipped in the first place. The installation of a pumping station in the country will provide all residents with amenities in the form of a constant supply of water from the hydraulic system, regardless of the pressure in it. Another function of the pumping station is.

The durability of the structure and the quality of the fluid supply depend on the correct installation. Before proceeding with the installation, it is necessary to study the information on this issue.

Classification of the station according to the place and method of installation

Depending on the liquid source, the station can be connected to three types of sources:

• well;
• well;
• water pipes.

The location of the unit can be:

In the first variant, the unit is located on a hill. This is necessary to prevent contact of waste water with the apparatus. To prevent vibrations, the machine must not touch the walls of the room in which it is located. The temperature in the room should be positive, that is, a heated room is needed.

In the second option, placement occurs at a depth of two meters or more. This is due to the freezing of the soil.

Station design options:

• single-pipe;
• two-pipe.

The first is used at a well depth of up to ten meters.

The second is installed at a well depth of ten to twenty meters. The model is supplied with an ejector. The estimate for the installation and location of the pipeline is calculated at the planning stage.

Design

The design of the pumping station consists of the following parts:

1. A centrifugal pump that supplies water from a well or well.
2. A hydraulic accumulator that regulates the pressure when the unit is turned off and on.
3. A pressure switch that turns off the device at high pressure and turns it on if the readings are too low.
4. Manometer, a device for measuring pressure.
5. Water intake system with non-return valve.
6. A pipe connecting the supercharger to the water intake system.

How to connect a pumping station?

The very first step is to develop a layout for the installation. The mechanism is located as close as possible to the source. Before installing the pumping station, it is placed on a rubber mat. This action will prevent the device from vibrating and prevent the device from falling into water. When placing the apparatus in a well, it is bolted to the shelf on which it will be placed.

Connecting a pumping station to a well, as well as installing a pumping station in a well, consists of the following steps:

1. A pit for placing pipes breaks out with a depth below the freezing of the soil. The length of the pipes for the pipeline is selected with a margin. The pipeline is laid in the dug trench.
2. At a depth below the freezing of the soil, holes for the highway are made in the well and the foundation of the building.
3. On the opposite side of the hole in the well, a shelf for the unit is attached.
4. A pipeline is being laid.
5. The pumping station is attached to the shelf with bolts. This action prevents the device from moving and falling into the well.

Laying the pipeline and installing the station

When installing a pumping station in a private house, the length of the pipeline, including turns, must be taken into account. Any connection must be tightly tightened with a wrench. When the pressure drops to 1.2 atmospheres, it is increased by compressors. The pressure of the accumulator is controlled using a manometer. To do this, attach a pressure gauge to the nipple and measure .

The required pressure of the pumping station to create pressure is 1.5 atmospheres. If the water pressure in the system is higher, then the user will be able to use the shower, while the load on the equipment will be increased, which will lead to wear. With reduced pressure, the system will not wear out, but the water supply will be at a low comfort level. For comfortable performance, it is necessary. The connection of the pumping station to the well is carried out after a thorough study of the schemes.

Setting up and starting the unit

After fixing the equipment and connecting to the trunk, the connection is made. This operation consists of the following items:

1. For the proper functioning of the intake pipe and the entire system, a filter mesh is attached to its end.
2. The check valve ensures that the pipe is filled with water. From the outside, it is attached with a coupling.
3. The end of the pipe is placed in a well or well.
4. A suction hose is connected to the supercharger, and a check valve is attached to its reverse side.
5. All joints are sealed with a special paste.
6. The pump is connected to the pipeline.

After completing the installation and connection, test the entire system. To check the pump, accumulator and line are filled with water. The motor turns on. The motor turns off when the pressure indicators are reached, until this moment the system is filled with water. To ensure automatic shutdown and activation of the mechanism upon reaching certain indicators, it is regulated.

The pressure switch is adjusted as follows:

1. In the case of self-assembly of the station, it is necessary to set the turn-off and turn-on indicators. There are two springs under the top cover. The big one is responsible for regulating the lower pressure, the small one for the pressure difference.
2. The device turns on. After the accumulator reaches the required performance, the tank is connected to the system and turned on. The pressure gauge readings are monitored. Permissible pressure values ​​must not be exceeded. In case of excess, the pump for the house is turned off.
3. After the blower is turned off, the relay is adjusted. To adjust the shut-off pressure, the nut marked "P" is rotated clockwise or counterclockwise. If the pressure indicator needs to be increased, rotate clockwise. To decrease, counterclockwise.
4. To adjust the indicators of the lower pressure limit and the subsequent inclusion of the supercharger, it is necessary to rotate the nut with the “DP” indicator. Rotate clockwise to decrease, counterclockwise to increase.

There is a rule for setting pressure indicators, which helps to prevent rapid wear of the membrane . The difference between the turn-on and turn-off pressures of the unit is ten percent in favor of the turn-on rate.

How to connect the pumping station to the water supply?

Do-it-yourself installation of a pumping station to the water supply system is appropriate if there is insufficient pressure in the general water supply system. If necessary, connect a boiler or domestic water heater to the system, the pressure must be sufficient.

To connect to the highway, use the tie-in or tee method. If the water supply is a polyethylene pipe with a diameter of thirty-two millimeters (this is the standard for such a material), then the tee method is used. If the water supply consists of a steel pipe, and its diameter is more than thirty-two millimeters, in this case, the tie-in method is used. Be sure to seal all connections with a rubber band to prevent leaks.

To connect the station, a ball valve is attached to the tie-in. A pipe is connected to the tap, connected at both ends to the couplings. The end sleeve is attached to the apparatus.

A ball valve is attached to the outlet of the unit using a fitting. A collet is screwed to it, suitable for a plastic pipe, and the pipe itself leading to the room is attached.

Nuances when connecting

Installation is carried out with a storage tank. The storage tank must be connected to a common water supply system. Before entering the housing, the water, passing through the tank, goes to the pumping station. After that, the wire and equipment setup should be installed. The installed water pump unit is configured. Connecting the pumping station to the water supply without regulated pressure will not function.

The pressure at the pumping station is adjusted as follows: after filling the cochlea with two liters of water, the device is turned off and on. Turn-off rates are three bars, turn-on rates are up to two bars. Screw P is used to adjust the cut-in pressure, screw DR is used to adjust the cut-off pressure. The screw is used as a pressure regulator.

When installed, the pumping station is necessarily provided with a filter for preliminary water purification. The filter is installed on the suction unit. The installation of the pumping station is accompanied by filter cleaning, since its contamination will lead to contamination of the entire system and a decrease in pressure in it. The adjustment of the pumping station is carried out painstakingly for the high-quality operation of the entire mechanism.

By installing a pumping station in the country, the user receives a constant pressure in the tap and comfortable use of water. A properly adjusted and tuned unit will last a long time.

Since the issue of water supply directly affects the life support of a country house, when choosing equipment, the consumer prefers, first of all, reliable devices, and in this series, the leadership, of course, belongs to the products of the Danish brand, especially since the proposed range allows each homeowner to choose a station model with taking into account his needs. And the scope of the equipment is quite wide and is not limited only to supplying water to the house: with the help of a pumping station, you can easily organize an automatic irrigation system in a garden or greenhouse, provide maintenance of the pool, and owners of city apartments with weak or unstable pressure in system.

For a private house, the Grundfos 45 pumping station of the MQ series can be the best choice, which can be used for sources with a depth of up to 8 m, while the device has enough power to pump water up to 45 meters away. The model of the same MQ 3-35 series has a lower power and is installed if the distance to the water intake does not exceed 35 m. You can also use these models to increase pressure both for a house with an autonomous water supply system and for an apartment with a centralized supply. An excellent choice for summer residents or gardeners can be models of the Grundfos JP series with a capacity sufficient for organizing autonomous water supply in the house, as well as for automatic watering or filling special pool tanks on the site. It is important to pay attention to the fact that the products of this series differ not only in power and performance, but also in the volume of the hydraulic tank.

The Scala2 pumping station has also gained rapid popularity among consumers, providing excellent pressure in a private house with an average water consumption. It is allowed to operate with a large number of water points - up to 8 units, while the installation has a low noise level, which does not create discomfort in the house. The power of the device is 2 kW, with a capacity of 3.6 m2 / h, the maximum depth of water rise is 8 m. A head of 45 m allows you to install such stations both in one-story houses and in two-story cottages.

The Grundfos CMB and CMBE equipment series refers to self-priming models, an important difference of which is the presence of a frequency converter. The main functions of this device which are reduced to adjusting the operation of the engine depending on the intensity of water consumption.

Products of the Grundfos trademark are presented in a wide range in the ALFATEP online store, and our experts are always ready to help you choose the right model of a pumping station for your home, taking into account the characteristics and volumes of water consumption. You can contact them by calling the hotline, as well as by asking a question of interest on the website of the online store website, in the feedback section.

At the request of customers, the delivery of equipment to the buyer's object can be carried out by the transport service of ALFATEP, and in the event that assistance is required in installing and connecting the pumping station, we recommend contacting our experienced craftsmen.

Owners of country houses, as a rule, have to deal with the problem of water supply not only for domestic needs, but also for watering the garden and vegetable garden. If the plot is summer cottage and is used only in summer, and the family consists of two people, then in this case you can purchase an ordinary household pump. This unit will easily provide its owners with the necessary amount of water.

To provide life-giving moisture to a large family, and besides, if the need for this arises not only in summer, but all year round, you cannot simply solve the issue. In this case, you will need the device of an entire water supply network, the uninterrupted operation of which will become possible only if a household, small-sized pumping station is installed. With its help, you can solve all issues of water supply, delivering it to the points of analysis quickly and without any interruptions.

For those who want to save money and connect a pumping station with their own hands, this article is intended.

The need for installation

Why do you need a pumping station for a country dwelling? Any such device is capable of independently pumping out from the source and delivering water to any point of its analysis. In addition, the installation of such a station contributes to an increase in pressure in the entire water supply system with a lack of power of a deep or surface pump, which is the main one.

What are the benefits of stations? They consist in the possibility of working for some time even when the power supply is turned off. It is also attractive that the device is able to create a pressure with which the normal water supply of the house and site is carried out. With all these positive qualities, the unit has a low weight, which allows it to be installed in any place convenient for this. In storage systems, the pumping station works like a tank, periodically turning on and off. This feature greatly reduces equipment wear. The pumping station will work for a long time, while eliminating the need to manually carry water.

Device and principle of operation

It will not be difficult for a person who understands at least a little in technology to understand the main elements of a pumping station. What is this unit? Its main element is a surface-type pump equipped with an ejector. It is able to supply water from a depth of 10 m and deliver it to the desired point. That is why the power of the pumping station is determined by the surface pump. How does it work? The suction line goes from the pump to the source. At its end, which is located in the water column, a grid and a check valve are installed. The pump is supplied with a steel pressure tank. The container has a closed structure consisting of two cavities separated by a membrane. Water enters one of them, and air enters the other under pressure.

What is a pressure tank used for? It is required to perform the following functions:

• protection of pipes and water supply connections from possible water hammer;
• accumulation of a certain amount of water, which is under pressure in one of the compartments, which makes it possible not to stop its supply in the event of a power outage.

Due to the property of fluid accumulation in the tank, it is also called a hydraulic accumulator. In some pumps, the volume of such a tank reaches 500 liters.

In addition to the above elements, the pumping station has a pressure switch. What is this item for? When the pressure drops below the critical level, the relay turns on the pump. It can also turn off the unit. This happens when the pressure rises to a certain level.

In addition, the pumping station must have a pressure gauge. This device shows the water pressure that is maintained in the line.

Pumps "Dzhileks Jumbo"

In order to provide water to a country house or cottage, you can use various models of this equipment. The pumping station "Dzhileks Jumbo" is produced by a Russian manufacturer. Such equipment easily ensures the availability of water, not inferior in this matter to city apartments.

The pumping station "Dzhileks Jumbo" is in demand for pumping other liquids, as well as for watering the garden.

The tank, which serves to fill the water, in this equipment is made of high-quality steel that can withstand high pressure. On one side of such a container there is a nipple. It is designed to be able to create and maintain the pressure necessary for normal water supply.

Grundfos pumps

This equipment is produced by the Danish concern Grundfos, founded back in 1945. Today, this manufacturer is the market leader in pumping equipment. At the same time, the high consumer demand for such devices is caused by their high quality and wide range.

The Grundfos household pumping station finds its application in individual households. At the same time, it performs the tasks of providing hot and cold water supply, sewerage and drainage.

If the Grundfos pumping station is installed correctly, and after that it was regularly serviced with the replacement of worn seals and bearings, then it can last for many years and delight the owners with its uninterrupted operation.

Location

As a rule, the units that supply water to the house and to the site are located in basements or caissons. How should the pumping station be installed in this case? The connection diagram provides for the obligatory maintenance of the greatest possible distance from such equipment to the wall. Otherwise, the pump may be damaged due to its strong vibrations.

The place where the water supply station will be installed must meet certain parameters, namely:

• due to the rather loud operation of the pump, the room must be isolated from noise;
• it should be dry, warm and have the possibility of regular ventilation;
• be at a distance as small as possible from the well or from the well, which will allow water to be sucked in with maximum power;
• have sufficient dimensions to carry out equipment repair work and take preventive measures.

For the placement of pumping stations, different options can be used:

1. Basements. This is an ideal place to install a pump, which should be foreseen in advance, at the design stage of a house. In it, installation can be done without much difficulty. Just remember that the basement should be warm and dry.
2. Caisson. This is nothing more than a special platform, which is located directly at the surface of the well. The main advantage of such a place lies in the heat generated by the topsoil.
3. The scheme for connecting the pumping station to the well provides for the arrangement of special departments in it. This option is cheap and quite simple. But it is worth remembering that such an arrangement of the pumping station will not allow access to it for the necessary repair and maintenance work, and will also reduce the pressure level when supplying water to the house.
4. A very convenient and practical option is to place a pumping station in the house itself. But at the same time, it is worth taking care of the soundproofing of such a room.

The unit should not be affected by various mechanical factors. When placing expensive equipment in the basement, you will need to make a stand for it. Such a pedestal will protect the mechanisms and the tank from groundwater.

What else needs to be considered when a pumping station is installed? The connection scheme provides for its location from the well at a distance of no more than 10 meters.

Connecting equipment

Choosing a unit for pumping water and deciding on the place of its installation is far from all that is required in order for the pumping station to start working. Its connection diagram must also be performed correctly. Otherwise, the entire system will work intermittently or not efficiently enough.

What will be the connection diagram of the pumping station? In each case, it depends on the location chosen for the equipment. But regardless of this, such a scheme will include the following:

• suction pipeline lowered into a well or well and going to a pumping station;
• the equipment itself;
• pipeline that goes further to consumers.

This is the general scheme by which a pumping station is connected for a private house. Bindings in each case may be different. The most common cases will be discussed below.

Well connection

When installing a pumping station in a house or in a caisson, the same scheme is used. Its beginning is the supply pipeline, which is lowered into the well. A filter is installed on it, as a rule, a mesh type. After this element is a check valve. Next comes the pipe.

The filter in this case is necessary as a protection against mechanical impurities. The installation of a check valve will be needed so that when the equipment is turned off, the water from the tank does not flow back into the well. This will allow the pump to turn on less often and extend its life.

The supply pipe is led out through the wall of the well. At the same time, its depth should be slightly below the existing level of soil freezing. Further, a trench is dug from the well to the installation site of the equipment. It has the same depth as the supply pipe. Trenching must be planned in advance. It must provide a minimum number of turns. This will reduce the amount of pressure drop and pump water from a greater depth. For greater reliability of the system, it is recommended to insulate the pipeline. To do this, sheets of expanded polystyrene are laid on top of it, which are then covered with a layer of sand and covered with soil.

The scheme for connecting the pumping station to the well at the entrance to the house provides for the passage of the supply pipe through the foundation. This place must then be insulated. In the house itself, the pipes can already be raised to the place where the equipment is installed.

If a pumping station is installed according to the instructions, then the system described above will work without any failures. The only inconvenience in this case will be digging a trench and entering the pipeline through the wall of the building. It will also be difficult to localize damage to the pipeline in the event of a leak. In order to minimize the likelihood of these problems, it will be necessary to lay high-quality pipes, and at the points of their connection, the arrangement of a manhole. If a high level of groundwater is noted on the site, then a trench for supply pipes will need to be dug above their level. At the same time, to prevent freezing of the water supply, a heating cable is laid near it. You will also need to insulate the cover of the well, as well as its rings.

Water connection

Pumping stations are sometimes installed on centralized water supply. In this case, they are needed to increase the pressure level of the fluid supply to the house. The scheme for connecting a pumping station to a water supply system is similar to that used for water intake from a well. Only in this case is a water pipe suitable for the inlet of the equipment. It also includes a filter and a valve. The output goes to consumers.

However, in this case, it is recommended to install a ball shut-off valve at the inlet. This element will allow you to turn off the entire system, for example, for repairs. A second shut-off valve is placed in front of the pumping station itself. It is necessary in case of repair of equipment or pipeline. It makes sense to put a ball valve at the outlet. Such a measure will allow, if necessary, to turn off consumers. Water from the pipes will not have to be drained.

Well connection

How to do the work in this case? Connecting a pumping station to a well is no different from previous schemes. Only the pipeline should exit at the point where the casing ends. It is here, as a rule, that a caisson is arranged, where a pumping station can be placed.

As in all the schemes described above, a filter is installed at the end of the pipe, as well as a check valve. At the inlet, for the convenience of the first start, you can put a filler tap through the tee.

Automation connection

There are 2 most commonly used schemes, with the help of which the necessary control equipment is installed at the pumping station. To carry out such work, you should study the accompanying documentation for the unit. It will definitely indicate the method recommended by the manufacturer.

The connection of the pressure switch of the pumping station must be carried out in a certain sequence. First, it must be connected to the water supply, and then to the electricity network.

In the first installation method, the relay is mounted directly on the pipeline. Installation is carried out using a tee, which is equipped with a fitting.

There is also a second way. When using it, the accumulator is equipped with a fitting with five outlets for the supply and distribution pipeline, pressure gauge, relay, and also for the accumulator itself. In order to measure the pressure in the pumping station, the relay is connected to a 220 V power supply.
