Alarm for drain pump panels
The alarm kit consists of a small plastic box with a cable input, a 12 V siren DC and a red signal LED. The alarm reacts if the water volume exceeds the maximum permissible level. In this case, the signal LED lights up and the alarm emits a long sound. The active phase of the alarm continues until the error is turned off or corrected. read in full >Press control
Press control has a built-in check valve, control panel and power button, and can also be equipped with an operating status and malfunction indicator. The press control device is mounted in the water supply system directly on the pump or in the pressure pipeline and provides constant water pressure. Press control turns on the pump when the pressure (due to water withdrawal) drops below the set value, and turns it off when the water flow stops. If... read more >Hydraulic accumulator for pumps
The design of the hydraulic accumulator is similar to an expansion tank and is a tank divided by an elastic and waterproof membrane into two containers. One container is filled with air or a nitrogen-containing gas mixture under low pressure, and water flows into the other. The purpose, operating conditions and functions of the expansion tank and hydraulic accumulator are different. There is also a difference in the design of these tanks. Structurally, hydraulic accumulators and expansion tanks differ in location... read more >Electrical cabinet for control and protection of pumps
An electrical cabinet (or switchboard) is a control device capable of controlling one standard pump or several. In addition, the electrical cabinet serves to protect pumps from “dry running” and from faults in the electrical network ( short circuit, phase failure, voltage drop, etc.). Switchboard equipped with terminals for connecting monitoring and control devices (level, humidity and temperature sensors), as well as general…Automatic pipe couplings are used for ease of installation of fecal, drainage and sewage pumping units to the pressure main. An advantage to the reliability of this connection is convenience and safety when lifting equipment for preventive examination or scheduled maintenance.
The automatic pipe coupling consists of 3 parts: the main part, the top mount of the guide pipes and the pump mount. The main part of the pipe coupling is attached to the bottom of the well with anchor bolts. Two guide pipes having the length of the fecal pit are inserted into the main part of the pipe coupling. The upper parts of the pipes are attached to the surface of the fecal pit. The third part of the pipe coupling to which it is attached fecal pump, slides along the guides. It, together with the main part, makes up the detachable connection of the pump.
Automatic pipe couplings can be purchased separately or as a set.
The couplings are compatible with pumps from any manufacturer (if the DN of the flange used by this manufacturer corresponds. DN65 - DN65 Coupling; DN80 - DN80 Coupling).

Sewer or water supply systems are complex structures made up of many elements: straight pipes, flexible and rigid adapters, composite connectors assembled from many segments. The flawless operation of the system as a whole depends on the quality of the design and installation of fittings. It is important to understand the characteristics connecting elements, and in the nuances of their installation. Pipe coupling - simple in design, but functional important detail.

Purpose and design of couplings
Pipes are nothing more than cylindrical metal or plastic pieces that are hollow inside. To connect them, a whole set of additional devices is required, from simple adapters to complex corner connectors. It is the fittings that provide strong and durable units that can be disassembled if necessary. Suppose a pipe coupling TP 4 is designed for a stable and hermetically sealed connection of steel products with a metal hose, but the threadless installation method does not allow replacement after some time.
Design transition elements simple:
- central rigid part (base);
- side fittings;
- screw;
- cap.
There are fittings various shapes and type of fixation. This depends on how the device is attached to the pipes.
Large diameter cast iron and steel couplings are used to connect underground pipelines
Types of pipe fittings
Large quantity various adapters are explained complex design building networks. The simplest is considered to be a pipe-to-pipe connection; the most complex is a unit that fixes products of various diameters with an angle of inclination or rotation.
Often, double-sided adapters are needed to connect a type “C” pipeline - these are double-socket couplings PVC 110. They “fit” the ends of large-diameter sewer pipes from the outside. For products with a smaller diameter, rigid plastic can be replaced with flexible one.
Double socket couplings are flared at the edges and equipped on the inside rubber seals
Features of flexible adapters
The flexibility of the fitting material allows you to increase the functionality of the network: make an angular bend or make an outline. For example, a pipe coupling MT32 (options from MT22 to MT50 are popular) is necessary to connect a flexible connection with a rigid product, but is itself made of durable aluminum. In this case, the flexibility of the fitting is not needed, since one of the elements is already movable.
In contrast to aluminum and zinc parts, polypropylene fixtures allow you to adjust the position of communications. For example, a flexible pipe-pipe coupling with a degree of protection IP65, due to the elasticity of the material, is used to connect rigid products at an arbitrary angle. The only condition is the use of pipes of the same diameter.

Automatic fixtures
The main purpose of the automatic pipe coupling system is contactless installation and disconnection of parts of drainage or sewer communications. Automation allows you to remove the pump from the pressure pipeline installation and take it to the top without lowering it into the well. Reinstallation is carried out in a similar way.
At the bottom of the well, an elbow is attached using anchors - a transition unit between pressure pipe and a pump. The supports for lifting the installation are two guide profiles, also attached to the knee. The pump is lowered down on a chain or cable along the guides and secured in a flange manner. Engagement occurs automatically.

Gebo connectors
The popularity of products from branded companies is achieved only by exceptional quality and 100% functionality. These are, for example, Gebo couplings for a metal pipe, unique and technical specifications, and for convenience installation work. Even a pressure of 10 bar and a carrier temperature of +75˚C are not obstacles to their use.
Installation experts highlight the main advantages of Gebo products:
- it is possible to connect pipes with a deviation of up to 3˚ from the common axis;
- suitable for multiple installations (with additional replacement of seals);
- differ in the ability to change sizes, which is important for adjusting the dimensions of communications;
- To change the wiring, it is possible to insert tees without changing the integrity of the structure.
Years of continuous operation without breakdowns or repairs is the main indicator of the quality of Gebo fittings.

Coupling installation methods
Hardware They are connected with threaded fittings, which cannot be called an advantage, because welded seams are still more reliable. The only drawback of welding is the inability to quickly disassemble the communication network.
For resistance welding polymer pipes require a special apparatus
Plastic products I bind using both the threaded method and compression, and with the help of welding machine. The latter is effective for welding PE pipes with couplings. When polypropylene and polyethylene reach a certain temperature, they begin to melt, as a result, the polymers of the adapters and pipes bond to molecular level. Of course, the connector must be made of a material similar to other products.
When installing adapters and connectors, it is important not only the quality of the material and product characteristics, but also the skill of installation, since any mistake entails a pipeline failure.
