Pumping stations are pressure equipment for the forced pumping of liquids. The technical characteristics of Vilo pumping stations make it possible to ensure water transportation to houses and plots not connected to a centralized water supply network.
The principle of operation and arrangement of pumping stations
The equipment of the German company Wilo is popular. Self-priming units supply water to a private house, utilities. Liquid is taken from wells and boreholes, and rain and river water can be used for household needs. Devices are used as emergency installations.
The design of a household pumping station includes the following required elements:
- normal or self-priming pump;
- expansion tank;
- pressure gauge and automatic relay to maintain pressure;
- tubes and connectors;
- protection against overheating and power surges in the electrical network.
The pumps are made of quality materials. Modern technologies can reduce noise, so the device can be successfully used in a residential area. Accumulative sealed capacity provides the user with a supply of water during a power outage.
The pipe going to the fluid source is connected to the system entrance. At the exit are elements for the distribution of water. The pump creates a pressure of about 2 atmospheres. Water begins to flow through the pipes after the tap is opened. When the valve is closed, the relay turns off the hydraulic pump after 5 minutes to fill the volume of fluid in the expansion tank.
Lineup and Specifications
To choose the right unit, you need to familiarize yourself with the technical characteristics of the pumping unit, evaluate the advantages and take into account the disadvantages. Each series of the model range is designed for specific purposes.

All models of Vilo pumping stations work with cold water that does not have solid inclusions. Each representative of the model range has its own characteristics: dimensions, power consumption, system pressure, degree of protection.
Features of operation and use
When buying a pumping station, attention should be paid to such characteristics:
- Determine the type of pump required. A device with a self-priming function is suitable if it is no more than 8 meters from the top water layer. Otherwise, look for submersible systems.
- When choosing a capacity, it should be noted that the average water flow through the tap is 4 liters, the shower is from 10 to 12. When calculating all points, the minimum throughput should be 2.7 m3 per hour, and the maximum - 8 m3.
- The pressure of the water depends on the height to which it is necessary to raise the liquid, taking into account the loss of horizontal path. At the same time, every 10 meters are equal to a meter of the water column. For highly located communications suitable pressure stations.
For smooth operation, it is not enough to correctly install a pump station. It is necessary to operate the system according to the instructions, to carry out preventive work in a timely manner by a specialist.
Advantages and disadvantages of Vilo pumping stations
Among the advantages are noted efficiency, reliability and smooth operation, as well as the strength of the case and high-quality materials of components. You can install the pump yourself. The system is not difficult to operate, there is a choice of manual or automatic settings. Some models are equipped with frost protection.
Among the shortcomings can be noted the low efficiency of circulation stations with a wet rotor. When using a centrifugal pump, water must be filled in manually before starting. If a check valve is installed, this must be done only before the first start-up.
Not all models are equipped with a trip device in the absence of water. Therefore, protection from working in the “dry” environment will be required. Dry rotor pumps are noisy during operation.
