Drain Pump Panel Alarm
The alarm kit consists of a small plastic box with a cable entry, a 12V DC siren and a red alarm LED. The alarm responds if the water volume exceeds the maximum allowable level. In this case, the alarm LED lights up and the alarm emits a continuous sound. The active phase of the alarm operation continues until the error is turned off or corrected. read in full >Press control
The press control has a built-in non-return valve, a control panel and a 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 a constant water pressure. The press control turns on the pump when the pressure (due to water intake) drops below the set value, and turns it off when the water flow stops. If… read more >Hydraulic accumulator for pumps
By design, the 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 enters the other. The purpose, operating conditions and functions of the expansion tank and the 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 >Electric cabinet for control and protection of pumps
An electrical cabinet (or switchboard) is a control device capable of controlling both one standard pump and several. In addition, the electrical cabinet serves to protect the pumps from "dry running" and from faults in the electrical network (short circuit, phase failure, voltage drop, etc.). The switchboard is equipped with terminals for connecting monitoring and control devices (level, humidity and temperature sensors), as well as a common ...Automatic pipe couplings are used for easy installation of fecal, drainage and sewage pumping units to the pressure line. A plus to the reliability of this connection is the convenience and safety when lifting equipment for routine inspection or scheduled maintenance.
The automatic pipe coupling consists of 3 parts: the main part, the upper mount of the guide tubes 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 are inserted into the main part of the pipe coupling, having the length of the fecal pit. The upper parts of the pipes are attached to the surface of the fecal pit. The third part of the pipe coupling, to which the fecal pump is attached, slides along the guides. It, together with the main part, constitutes the detachable connection of the pump.
Automatic pipe couplings can be purchased separately or as a set.
Couplings are mated with pumps of any manufacturer (provided that the flange used by this manufacturer corresponds to Du. Du65 - Coupling Du65; Du80 - Coupling Du80).

Sewer or plumbing 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 the fittings. It is important to understand both the characteristics of the connecting elements and the nuances of their installation. The pipe coupling is simple in design, but functionally important detail.
Video review of the pipe coupling from the manufacturer
Purpose and design of couplings
Pipes are nothing more than metal or plastic pieces of a cylindrical shape 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 assemblies that can be disassembled if necessary. Suppose a pipe coupling tr 4 is designed for a stable and tight connection of steel products with a metal hose, however, the threadless installation method does not allow replacement after some time.
The design of the transition elements is simple:
- central rigid part (base);
- side fittings;
- screw;
- cap.
Fittings come in various shapes and types of fixation. It depends on how the device is attached to the pipes.
Large diameter cast iron and steel couplings are used to connect underground pipelines
Varieties of pipe fittings
A large number of various adapters is explained by the complex design of building networks. The pipe-pipe connection is considered the simplest, the most complex is the knot that fixes products of various diameters with an angle of inclination or rotation.
Often, two-way adapters are needed that connect the pipeline according to type “C” - these are two-socket PVC 110 couplings. They “tighten” the ends of large-diameter sewer pipes from the outside. For products of smaller diameter, rigid plastic can be replaced with flexible one.
Double-socket couplings expand at the edges and are equipped with rubber seals on the inside
Features of flexible adapters
The flexibility of the material of the fittings allows you to increase the functionality of the network: to make a corner bend or to make a stroke. For example, a mt32 pipe coupling (popular options are from mt22 to mt50) is necessary to connect a flexible input with a rigid product, but it 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 an IP65 degree of protection, 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 the non-contact installation and separation of parts of drainage or sewer communications. Automation allows you to remove the pump from the installation of the pressure pipeline and get it up without descending into the well. Reverse installation is carried out in a similar way.
At the bottom of the well, with the help of anchors, a knee is attached - a transition unit between the pressure pipe and the pump. Supports for lifting the installation are two guide profiles, also fixed on the knee. The pump is lowered down on a chain or cable along the guides and fixed in a flange way. The engagement takes place automatically.

Gebo connectors
The popularity of products of branded companies is won only by exceptional quality and 100% functionality. Such, for example, are gebo couplings for a metal pipe, unique both in terms of technical characteristics and ease of installation work. Even a pressure of 10 bar and a carrier temperature of +75˚C are not obstacles for their use.
Assembly 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 dimensions, which is important for fitting 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 and repairs is the main indicator of the quality of Gebo fittings.

Coupling mounting methods
Metal products are connected with threaded fittings, which cannot be called an advantage, because welds are still more reliable. Welding has the only drawback - the impossibility of quickly disassembling the communication network.
For resistance welding of polymer pipes, a special apparatus is required
I connect plastic products with the threaded method, compression, and with the help of a welding machine. The latter is effective for welding PE pipes with couplings. Polypropylene and polyethylene, when a certain temperature is reached, begin to melt, as a result, the polymers of adapters and pipes bind at the molecular level. Of course, the connector must be made of a material similar to other products.
When installing adapters and connectors, not only the quality of the material and product characteristics is important, but also the skill of installation, since any mistake entails a pipeline failure.
