Do-it-yourself water pump: make a home-made, centrifugal and membrane pump for water, a pump and a pumping pear. How to make a homemade manual water pump

After the purchase garden plot the summer resident has to solve the most difficult task in life: to settle down in a new place. The most important thing is to establish water supply, because imported water will not be enough for a long time. The problem of watering is also not solved in this way.

It is good if the house is located near some body of water: a river or a stream. In this case, you will need a pump for water supply. As an option, you can consider a homemade water pump. Such a device can be made from various materials. Water is being collected in the following way: the person makes a forward movement and allows the internal valve to move, while water flows out through the hose. Using a pump will alleviate the problem of watering.

This article provides ideas for making models of mini water pumps or mini pumps, as they are called by many. These are simple and cheap homemade products that will definitely come in handy in household to pump water.

Important! Well water can be raised to an aboveground tank using one of two types of pumps: piston or centrifugal. Both of them, although they work on different physical principles, are designed to solve the same problem of delivering or moving water from one place to another. When choosing the type of pump, energy consumption is taken into account, as well as the ease of troubleshooting in the event of a breakdown.

Pump characteristics

How to make a water pump with your own hands? To create a pump, the first thing you need is materials. In doing so, you need to focus primarily on the following criteria:

• Power, on which the speed of pumping water from the well depends. On average, for pumping from wells, wells, reservoirs and storage tanks it is equal to 350-400 W;
• The maximum degree of pressure. Approximately the required pressure for watering the garden is 40 m;
• Strength and moisture resistance of the material. For instance, best material body - cast iron, impeller - brass, shaft - stainless steel, mechanical seal - ceramic graphite.

If all of the above criteria are taken into account, then it will be possible to build efficient pump, and pumping water from the well will be carried out in a matter of minutes.

A cheap water overflow pump can be made from almost nothing: from two plastic bottles with and without cork, a piece of plastic pipe suitable diameter and drain hose.

Production process

1. First, the valve is cut out, for which the gasket is removed from the cover and cut in a circle. In this case, the gasket in diameter should be smaller than the neck of the bottle;
2. An eight-millimeter hole is drilled in the center of the bottle cap. Next, a gasket is inserted, the cut neck is screwed - all this is done to clamp the membrane and obtain a petal valve. A pipe is inserted into the finished valve;
3. From the other bottle, a kind of funnel is made, which is fixed on top of a plastic pipe;
4. A drain hose is put on the other end of the pipe.

In this way, the simplest do-it-yourself pump is made for pumping water. With the help of a sharp movement of the hand up and down, water is brought through a plastic pipe to the spout. Further, the liquid flows by itself.

Diaphragm pump

To do diaphragm pump with your own hands, you must first disassemble a similar failed unit and see how it works. The device includes:

• two compartments located opposite each other;
• high-strength membrane;
• distributor.

During the operation of the device, one compartment is filled with air, the other with water. As a result of displacement, water begins to move through the chambers. When the position of the membrane is changed due to the operation of the valves, it is discharged through the pipes.

Dismantle the air-operated diaphragm pump having compact dimensions and light weight, can be done in three minutes. This will require only two keys. So, in order:

• the rod with the drive shaft is removed from the very center of the pump;
• the membrane is removed;
• valves are removed, which prevent the back suction of the pumped medium.

Regulatory and shut-off valves – necessary elements in every water system, their purpose is to regulate the flow of water.

Having studied internal composition, you can start self assembly devices.

For information. Applications of diaphragm pumps are very diverse: chemical, oil, paint and varnish, food industry. The main advantages are: no piston, no need for gaskets, inability to spark. The principle of operation is based on the laws of hydraulics and pneumatics.

How to make a hand pump

The water pump is very necessary in the spring and in summer season. To do hand pump for water with your own hands, just look through thematic pages on the Internet. The solution can be found by examining several options. Preference is most often given to Soviet-era designs, they are many times more reliable and better than the current ones.

So, how to make a manual well pump for an eight-meter well? For this you will need welding machine and used materials.

Main details

• five-liter carbon dioxide fire extinguisher with a wall thickness of 5 mm;
• two three-quarter drives - one for the spout (side), the other for the water intake (below);
• sealing rubber;
• half inch pipe - 1 meter;
• two valves;
• a pond with a diameter of 14 mm for the stem, so that it fits perfectly into the fire extinguisher head;
• lever 12 mm thick, 28 mm wide and 70 cm long;
• basic support post 12 mm thick, 28 mm wide;

Additional elements are also used:

• a bed measuring 7x30x25 cm, on which everything is attached;
• mounting bracket 4x35 mm;
• steel handles for carrying the structure;
• M8 bolts for attaching the lever arms.

Three-quarter-sized drives are taken to increase the passage and reduce the load when pumping water. You can make them half an inch. The spurs are welded to the pump housing (fire extinguisher). But first, the body itself is made.

Description of the manufacturing process

The principle of operation of the pump is to create a vacuum suction well water, on this basis a device is created.

1. The bottom of the fire extinguisher is cut off. Between its body and the bed, sealing rubber is laid, previously cut to the size of the body. In this case, the structure is fixed to the base in four places with the help of corners. Bolts and washers are used for fastening. Holes for simplification can simply be burned in the metal on which the rod walks. This hole is central and must be done carefully with a welding machine;
2. A thread is welded to the stem and a return piston is screwed in, which plays the role of a check valve in the system. A five-millimeter metal circle with 10 mm holes is used as a piston for the passage of water. On top of it, a cuff cut from ordinary sheet rubber is put on a rod of the same diameter;
3. The entire unit rests on support legs, which are mounted on M12 bolts. The legs are screwed into nuts welded to the frame. The design is completely collapsible;
4. Upon completion of all welding work, the pump is primed and covered with paint.

The rod is rigidly connected to the handle. When the rod starts to move, the cuff rises, and the water, seeping through the holes of the piston, rises to exit through the side run (column spout). The pumping handle should oscillate freely left and right.

The pump pumps out approximately two to three liters of water at a time. Such a pump for pumping water is useful for taking water from a reservoir such as a well, a well.

For information. All pumps use the basic forces of nature to move fluid. As soon as the moving parts of the pump begin to move, the water is pushed to the side.

Alteration of the Chinese pump

Surely many burned themselves on the purchase of brushless pumps Chinese made. The devices are not bad, but they often break down: the stuffing of the pumps itself is covered - electronics flooded epoxy resin. The Chinese rocking chair serves a maximum of two weeks on a solar collector. Having a little knowledge of the principle of operation of the device, you can remake Chinese water pumps with your own hands. It will turn out, as in the saying "If you want it to work the way it should, do it yourself."

How to make a water pump from a broken Chinese product? First of all, disassemble the pump, look at the assembly diagram. Of the parts for assembling a new device, an impeller is useful, it is difficult to make it yourself.

New homemade pump for water is assembled from a powerful Soviet-era engine, a coupling and a Chinese-made impeller. Creation is set to solar collector, and the issue with the pump disappears for a long time. It will work efficiently.

Important! A converted do-it-yourself well pump will need to be covered from dust, which is a common cause of breakdowns in motor equipment.

The made unit is attached and tested in action. Such a homemade pump perfectly pumps water from a two-meter depth. It will last for several years for reliable operation, given how it works cyclically.

For seasonal irrigation, devices with a minimum of wear parts are mainly used:

• asynchronous centrifugal pump, made by hand;
• three-phase brushless unit.

In terms of popularity, the design of the centrifugal electric pump for water surpasses many pumping devices of this purpose.

Making a pump for pumping water, if you figure it out, is not difficult at all. Made by hand, it will become reliable and effective tool for household needs: watering, fence drinking water from the well. Such a technically simple design will help reduce the consumption of electricity and water.

Supplying water from a well or any body of water is not a particularly difficult task for the owner. However, it has become the subject of attention of "homemade" who are wondering how to make a water pump with their own hands, seeking to apply original solutions, allowing you to provide moisture to your household using a homemade water pump. Moreover, it is considered especially chic to solve the issue of creating structures that perform the task without energy consumption, using the laws of physics and natural phenomena.

Use of wave energy

This method is applicable if the site overlooks the shore of a reservoir. For the pump, you will need a log and a pair of stakes, a piece of corrugated plastic pipe and two valves.

A log with a length of 2.5 - 3.0 meters is equipped with wire loops with a diameter of 6 mm at the ends. From below, a piece of corrugated pipe is attached to it, pre-equipped with valves on plugged end holes. When the wave lifts the log, the pipe lengthens and water is sucked in through the bottom inlet. As the log is lowered, the tube compresses, squeezing fluid through the top outlet valve. The process is repeated with the cycle of wave oscillations. Such a device is capable of lifting water to a height of 25 meters. A manufacturing feature is the need for careful processing of the float protective coating from soaking wood in water. Easiest to apply traditional way drying oil impregnation. To increase efficiency, it must be applied in a hot state, repeating the operation 3-4 times.

Use of solar energy

Such a water pump is the easiest to make, since only a hose is needed for its manufacture, it is best to use a 2-inch plastic one. It needs to be spread out in rings over the surface, or it can be hung on a wire between two pillars. A check valve must be installed at the connection point. The hardest part is filling the hose with water. After that, the water in it will begin to heat up and rise up. From the overflow point, where the hose with a slight slope goes to the water collector (storage tank), it is necessary to protect it with a reflective coating, for example, with aluminum foil. When the heated water provokes movement through the hose, a reduced pressure will be created in it in the area of ​​​​the check valve, it will open, and the liquid from the source will begin to flow into the hose, where it will also begin to heat up. The device is capable of lifting water from wells or wells from a depth of up to 8 meters.

More complex structures to make a pump with your own hands are wind devices. They involve the use of more or less complex kinematics. However, original solutions with flexible drives, forms of wind catchers and other mechanisms are also possible here. wind power units may be included piston pump or a membrane pump for pumping water.

Manual transfer devices

Such units are most often used to lift water from Abyssinian wells or wells. Its main advantage lies in the possibility of using it autonomously, without the use of electricity. Do-it-yourself pump can be made in this way:

1. Foundation. The bearing part, on which the entire structure is attached, which is a do-it-yourself well for a well.

Fig.1. Base for installing a hand pump

The best for the manufacture of this part is a plastic material - textolite or fiberglass with a thickness of about 20 mm.

2. Flange. Transition piece that connects the casing to the base. The connection on the thread of the feed pipe and the flange is mandatory to prevent water from leaking back into the well.

Fig.2. bottom flange

The part is installed on the upper casing pipe along the thread and the body is attached to the part through the base with M6 screws in the amount of at least 8 pieces. Material - stainless steel or textolite.

Designed to block the opening of the feed pipe.

Fig.3. bottom valve

The counterweight rod protects the valve from tipping over during operation, the seal is sponge rubber 5-6 mm thick, the body is a steel sheet 4-5 mm thick.

4. Limiter. Designed to prevent the valve from moving away from the axis of the installation and its positioning during operation.

Fig.4. Stop - valve travel limiter

Racks - stainless steel bar with a diameter of 4 mm (electrode cleaned from coating), ring sheet 2 mm stainless steel.

5. Body. It contains all the working bodies of the pump, which provide pumping of water and its discharge.

Fig.5. Pump housing

The material for manufacturing is a plastic pipe with a wall of 10 mm or stainless steel with a wall of at least 8 mm. The holes in the lower part are designed for assembly with the base and bottom flange with 8 M6 screws. In the upper part, you need to make a hole with a diameter of about 50 mm for a drain outlet.

6. Piston with valve. Serves for pumping water from the supply pipe to upper part body, to the drain hole, using a petal valve.

Fig.6. Piston assembly

The piston diameter is 2 mm smaller than the internal size of the body tube, so sealing material must be wound up at the recess. It may be FUM tape, but we recommend using ordinary nylon thread, soaking it with oil. You can use sunflower, but it is better to use food vaseline.

You can attach a lever made of a strip of 20 x 4 mm to the part of the earring on the piston, with which you can already pump out the water. More often, a lever is used, mounted on the piston through a bracket attached to the body.

How it works

Applying force to the lever in the upward direction, you need to give it movement. In this case, a negative pressure is created in the released cavity, which raises check valve and draws water from the casing into the casing.

When pressure equalizes, the check valve lowers and closes the opening to the casing. When the piston moves down, an increased pressure is created in the cavity, which opens the petal valve, as a result of which water passes into the upper cavity to the drain hole. Through it, it is poured into a container prepared in advance. The result is a simple pump - a homemade rocking chair for water, in which you have invested your work and ingenuity.

Fig.7. Pump Assembly Diagram

Thus, using scrap materials, you can make a manual water pump with your own hands.

There are many other designs on how to make a hand pump, quite reliable and simple.

Fig.8. Scheme of a device for pumping a membrane type

An example of such a device is an elementary water pump, shown in Fig. 8, equipped with an electric drive. The working body in such a device is a membrane. Pumping is provided by two valves. Such a mini pump is often used for aeration in an aquarium, but this principle can be used to make an electric pump for pumping liquid. In the same way, you can arrange a hand pump for water.

Conclusion

The variants proposed in the text are not an exact study of the design, but make it possible to evaluate the principles of construction of such products. What happens next depends on your own ingenuity and the materials and products available.

In the article you will find assembly instructions original models pumps that you can make yourself, without specific skills and knowledge. The cost of these models is minimal, and sometimes they can even be assembled from improvised materials and household waste.

A water pump is almost the first necessity in a country household. Manual and motorized pumps are also used to transfer other types of liquids - fuels, solvents, oils, etc. Possibility to purchase expensive reliable pump there is not always, and cheap models break, as a rule, at the most inopportune moment. We will look at options for creating pumps from improvised material and parts that can be found in every workshop, and their market value is simply negligible compared to a new factory product.

Option number 1. Water pump for overflowing water

The primitive design for pumping water, which can be assembled in 10 minutes, will serve as a handy handy tool for gardening. This is especially convenient when you need to repeatedly draw water from a barrel with buckets. In fact, this is a check valve mounted on a tube with a branch.

For manufacturing, you will need a tube, a hose and several necks from plastic bottles as an assembly.

Working process:

1. We take out the gasket from the cork and cut it 2 mm less than the diameter of the cork, leaving the 3 mm segment intact.
2. We drill a hole 10 mm in the center of the cover.
3. We install the petal in the lid and screw the cut neck. It will press the remaining segment.
4. We insert the valve into the stem tube and put on a “skirt” from a cut plastic bottle.
5. From the opposite end we put on the outlet hose.

This device is actuated by several clicks on the axis of the rod, when the intake part with the valve is immersed in water. Further, the liquid will go by gravity, as long as there is a level difference. Then the water can be raised by immersing the rod in the barrel.

This is the only product with a "negative cost". When creating it, you will not only spend nothing (except time), but also dispose of household waste with benefit.

Option number 2. A simple do-it-yourself hand pump

In this manual, we will give an example of a manual pumping system, which can be taken as a basis for creating a stationary water-lifting post on a well or well.

BUT - Classic scheme manual pump. B - A variant of a homemade pump from plastic pipes. Device diagram: 1 - inlet pipe; 2 - check valve; 3 - piston; 4 - check valve; 5 - stock; 6 - rod, combined with the outlet pipe; 7 - pump drain

For work we need:

1. Pipe sewer PVC 50 mm with bends, plug and cuffs-seals - 1 m.
2. Check valve 1/2" — 2 pcs.
3. Pipe sewer PPR Ø 24 mm.
4. Rubber, bolt/nut pairs with washers Ø 6-8 mm.
5. Clamps, shackles, fitting clamps, other plumbing parts*.

* The design of the pump can be individual depending on the availability of spare parts.

Method 1. Draining through the handle

This model is the simplest of the home ones - water rises along the piston rod, which is made of a PPR pipe and pours out from above.

1. We cut off a pipe Ø 50 mm 650 mm long - this is the basis for the sleeve.
2. We make the end petal valve. To do this, we drill 8-10 holes Ø 5-6 mm in the plug and cut out a round flap of rubber (3-4 mm) with a diameter of 50 mm. We fix the flap in the center of the plug on a riveting or bolt (a self-tapping screw does not fit!). The reed valve is ready.
3. We install the plug into the pipe (sleeve) on the sealant through the seals and additionally fix it with self-tapping screws through the pipe wall.

1. IN PPR pipe(700-800 mm) install a check valve. This can be done in the “hot” way - heat the end of the pipe and insert a fitting with a valve into it, which should let water flow in the direction of the pipe (piston rod). Strengthen the connection with a worm clamp while warm (before cooling).
2. The piston head can be made from a used 330 ml sealant tube, or rather its nose. To do this, it must be pre-heated and placed in a sleeve - so the head will take the ideal shape and size. Then it should be cut and installed on the check valve in series using a coupling with external thread or union nut "American".
3. We insert the piston into the sleeve and make the top plug. It does not have to be tight, just keep the stock straight.
4. On the free end of the rod (pipe) we install a 90 ° drive. In the future, a hose is put on the squeegee.

Assembling a hand pump on video

Such a pump is very reliable, but not very convenient - the water outlet point is movable, moreover, it is located close to the operator. It can be slightly modified for convenience.

Method 2. Side drain

A 35° elbow must be included in the sleeve. The design is identical to the first option, but in the piston rod pipe we make big holes, without violating the structural rigidity, or we use a rod rod. In this case, water will flow into the sleeve and rise by the operator's reverse effort to the spout.

Video pumps with side discharge

The main advantage of the described pumps is low cost finished structure. Repairs are made in a few minutes by replacing (or gluing) "penny" parts.

Option number 3. Spiral hydraulic piston

Behind this formidable name lies an ingenious device for supplying water from a river over a short distance. This device is based on a carousel with blades - similar to the wheel of a water mill. The carousel is driven by the river flow.

The pump in this case is a spiral made of a flexible pipe Ø 50-75 mm, fixed with clamps to the wheel. In the intake part (closer to the outer contour), a ladle from a pipe of a larger diameter (150 mm) is attached to it.

The main assembly is a pipe reducer through which water will flow into the pipeline. It can be taken from factory equipment or a cesspool pump. The gearbox is located along the axis of the wheel and is rigidly fixed to a fixed base.

The maximum height of water rise will be equal to the length of the pipe (from the intake), which is completely immersed in water during operation. That is, this is the distance in plan from the point of immersion to the point of exit, which the water intake bucket passes. At the moment of immersion in the pipeline, closed system with air areas, and water passes through the pipe to the center of the spiral.

Of course, such a pump is not suitable for everyone - in the end, the river acts as an activator. But for watering summer period this is a great option. The cost of such a device is difficult to predict - great importance has available material.

Option number 4. Pump from the compressor (airlift - airlift)

If the farm already has a compressor, do not rush to purchase an additional pump. You can assemble a simple water lift literally from two pipes.

The first pipe is used to supply water. For economic needsØ 30 mm will suffice. The second is needed to supply air from the compressor. Diameter 10-20 mm.

The efficiency of the airlift pump directly depends on the compressor power, immersion depth and delivery height. It cannot exceed 70% due to the design features. The efficiency will be equal to the immersion depth divided by the sum of the immersion depth and the ascent height (the entire water path). In most cases optimal power compressor is set empirically.

Water supply has long been the number one task for the survival of entire cities. Today, energy savings and natural resources There are fewer and fewer of them, and they are becoming more and more expensive. Therefore, a partial return to the original technologies without electricity and gasoline is a natural phenomenon. Perhaps in the future this will be the key to a healthy and harmonious life on our planet.

Perhaps in the future this will be the key to a healthy and harmonious life on our planet.

The summer cottage and the presence of a well on it are a joy for every nature lover. Especially if electricity is supplied to the village and it is possible to pump water for irrigation from a well using a powerful unit.

But what to do in the event that there is no electricity at all or it was temporarily cut down ?! Of course, you can carry water to the beds simply with buckets, but this is tiring, and just a long time. Especially if the garden lands have a large area.

We bring to your attention a solution to the dilemma - assembling a water pump with your own hands. And believe me, such a water machine will work, albeit a little slower than an electric pump, but still, quite productively. Consider several options for hand-assembled pumps.

Is it worth thinking that the production of your own pump at home is not profitable and will not lead to anything. We are ready to prove the opposite to you, referring to several advantages of such work:

• Firstly, the summer resident will always have a device at hand to supply water from the well upstairs, even if the electricity is turned off.
• Saving is also important. family budget. So, electricity tariffs are growing by leaps and bounds, and a powerful pump in working order winds up a lot of kW. Such cycles of the pump, even for the purpose of watering the beds in a month, can result in a tidy sum for the average family.

Important: you can only assemble a manual piston pump with your own hands. All other types of pumps (vane, diaphragm, slide) are more difficult to self-assemble.

Operation and arrangement of a piston unit for a well

A piston is installed in the flask (body) of the pump, which, under the influence of exerting physical force on the lever, moves up and down. The piston has an inlet and an outlet closed by valves. At the moment the lever is pressed, the piston descends down the flask and opens the inlet valve. Water fills working chamber, the pressure rises. Due to the pressure difference, water is pushed out through the outlet valve of the device.

Important: the performance of a piston-type pump averages 2-3 liters per cycle (pressing the lever). But at the same time, it can be increased if the cross section of the housing and the piston in it is increased. Most often, these pumps are used for Abyssinian well. But provided that the pump is securely fixed, it can also be used with a conventional well.

Stages of work on creating a pump

• First you need to prepare the cylinder body. It can be made from a pipe cut desired section. It is desirable that the pipe diameter is at least 8 cm. And its length is 1 meter.

Important: the section of the housing for the hand pump does not have to be round. It can be either a square or a polygon. The main thing then is to fit the piston section to the shape of the body.

• Now two brackets must be welded to the pump body so that the future lever fits freely between them. Brackets are attached to the top of the pump.
• The next step is to drill holes for the inlet and outlet pipes. Accordingly, we make holes in the lower and upper parts of the case.
• The lower part of the case must be closed with a lid. It can be metal fixed by welding, or just larch. The latter is in excellent contact with water, without rotting.
• It is also necessary to close the upper opening of the flask with a lid. This is not necessary, but having a cover will increase the efficiency of the pump and prevent water from splashing as it rises.
• In the top cover we make a hole for the stem. It should be in the form of a gap.

Making a piston for a pump

Now you need to make the main working unit of the pump with your own hands - the piston. It must be made from the following materials:

• A metal disc, the thickness of which should be about 3-4 cm;
• A cut of dense rubber of the same section as the piston (the thickness of the material must be at least 5 cm).
• On the entire surface of the piston (metal disk) we make holes with a diameter of about 1 cm. There should be several of them.
• Cover the disk from above rubber gasket and connect them.
• A cut must be made through both elements of the piston in the central part in order to securely fix the rod.
• A rod made of metal or steel can be used as a rod. Its length should be 1-1.5 m. We pass the rod through the hole formed in the piston and fix it from below with a strong nut.
• We attach the upper end of the rod to the lever after it is withdrawn through the top cover of the housing.

Making a lever

It remains to make a working pump lever. To do this, take a pipe with a diameter of 3 cm and a length of about 35 cm. One end of the pipe must be flattened with a hammer and a hole for the bolt made here. In the future, a bolt will pass through it, which will also be located in two brackets. This is how the lever is attached. The upper end of the rod is also brought to the bolt, securely fixing it. outer side the working lever can be wrapped with electrical tape or put on a piece of rubber hose for easy grip.

We mount the inlet valve from a piece of dense rubber. Its diameter should be slightly smaller than the inlet. We form a hole in the central part of the valve and mount the guide into it. It is thanks to her that the valve will always return to its place after the piston returns to its usual position.

Important: the guide must be longer than the distance from the drain pipe to the lower end of the pump housing.

The finished pump is mounted on a pipe, the length of which should reach the water mirror in the well. It remains to securely fix the pump at the walls of the source in order to freely raise water from it.

fire pump

One more simple design well pumps. In this case, you need to prepare the following materials:

• Metal barrel with a volume of 150-200 l;
• Outlet tap;
• Water intake hose;
• Bricks for laying a small stove.

We assemble the structure in this way:

• First, we lay out a small brick stove so that a barrel is placed on it.
• Now in the side part of the tank at the top we make an inlet, and in the side part below - an outlet under the tap.
• We attach a hose to the inlet pipe, the length of which will reach the water mirror in the well, to the outlet - a faucet.

Such a pump will work according to the following principle:

• First, pour 3-5 liters of water into the barrel.
• We make a fire in the oven and wait until the water heats up well.
• Put out the fire in the oven. After that, the heated air will go into the well, and the pressure in the tank will become rarefied. As a result of this phenomenon, water will begin to flow into the tank. As soon as the barrel is full, you can open the tap and take water from the tank through a standard hose attached to it.

solar powered pump

And you can make such a pump for the well, which will work from the sun. To make it yourself you will need:

• A metal can of any capacity (the more the better, but, as a rule, they take a tank of 50 liters;
• Rubber heating pad;
• A metal tube in the form of a lattice filled with propane-butane;
• Two valves - inlet and outlet.

Assemble the structure in this way:

• A rubber heating pad (pear) is mounted in a can, we first tightly connect it with a tube in the form of a lattice;
• The grid is placed with sunny side a well, however, like a can;
• We attach a hose to the inlet pipe, and lower its second end into the well;
• The outlet is closed with a valve in the form of a faucet.

Such a home-made pump will work under the influence of heating propane-butane in the tube. He boils at the most low temperatures. As soon as the tube warms up, it needs to be watered. cold water, after which the material cools down. This, in turn, will inflate the pear, and water will begin to flow into the tank. The tube at this point will heat up again and immediately cool down due to the water passing through the system. The process of continuous pumping of water from the well will be ensured.

So, it became clear that it is very easy to make a pump for a well with your own hands with minimal skill.
