To help deal with the fundamentally important technical characteristics of pumping stations agreed Maxim Sokolov is an expert at the online hypermarket VseInstrumenty.ru.
– The pumping station ensures the stable operation of the water supply in a private house. Its main goal is to maintain the necessary water pressure, which is necessary not only for a comfortable shower, but also for the operation of household appliances. For example, if there is insufficient pressure, the washing machine or water heater will not even turn on. The pumping station solves this issue and works automatically – the engine starts thanks to the built-in pressure switch.
The main parameters will be:
- Power. Affects the performance of the pumping station. For example, 300-600 W models are capable of pumping 30-40 l / min. More powerful (from 1000 W) pump over 60-100 l / min. A high value is required if the house needs water not only for household and hygienic needs, but also for the operation of household appliances (washing machine or dishwasher).

- Lifting height. Indicates the maximum height to which the pump can lift a liquid column. It must be greater than the pressure loss in the pipeline on the way from the source to the draw-off point. And the greater the difference, the more liters per minute the station will be able to produce. The most common models with a value of 20, 30, 40 m.
- Suction depth. Shows how far the station should be from the water table. Usually this value is 8-9 m. You can increase it with the help of an additional option – an ejector.
- Hydraulic accumulator volume. Affects water supply. The larger it is, the less often the pump will turn on. For example, for a summer residence, a model with a 24-liter tank is enough, for a private house where more water is consumed, it is worth choosing a 50-liter equipment.

Editor’s Choice
1. Grundfos CMBE TWIN 5-62
Surface pumping station targeted at a large household. Throughput – 11,2 cubic meters. m / h, maximum pressure – 44,2 m. Works from a stationary power supply, consumes 1500 watts. The operating temperature range is from -20°C to 55°C. With excellent performance, the station is quite noisy (55 dB), so it is better to install it in a non-residential area. There is a function of increasing the pressure and protection against dry running. The model is available in 2 variations: with a terminal block or a socket, the technical characteristics are identical.

How to choose a pumping station for your home
Answers questions about choosing a pumping station Mikhail Terentiev, head of household equipment sales at Grundfos.
What are the important characteristics of the product should be guided by when choosing?
– The water supply station is a key element of the household’s life support system. The choice of a specific technical solution depends on the type of water source and the characteristics of its location. To raise water from sources located below ground level (a well, a shallow well “on the sand”), a river and other reservoirs use pumping stations based on self-priming pumps. They can be of different designs, but they have a common feature: inside the hydraulic part of such a pump, an area of rarefaction (low pressure) is created, which ensures the suction of water from a depth.
Very important selection criteria are the pressure that the pumping station is capable of creating and the water flow that it provides. The pressure determines the possible height of the water after the pump. For example, if the pressure is insufficient, water from the taps on the top floor will not flow. Flow rate is the amount of water that flows out simultaneously from all taps, including faucets, showers, toilets, irrigation systems, etc.
Pumping stations with built-in automation are more convenient and easier to use. They are typically all-in-one all-in-one solutions and are ready to go right out of the box. However, in some cases it is advisable to use solutions with a remote control unit.
Another important point is the presence of a built-in frequency converter. This is a device that smoothly regulates the performance of the pump depending on the flow in the system (that is, on how many taps are open at the same time) and maintains a constant pressure. For example, in a system with a frequency converter, the water pressure in the shower will be constant, regardless of whether someone else is using the water in the house at that time or not.
Since the water supply system must work constantly and without failures, high demands are placed on pumping stations in terms of their reliability and durability. Cost is also an important selection criterion, but you need to understand that cost is not only the purchase price, but the cost of maintaining, repairing and replacing equipment during its entire service life.
For example, more expensive equipment, for which the manufacturer gives a five-year warranty, may end up being much cheaper than the “budget” option with a one-year warranty, which will burn out a couple of times in five years. The availability of the service and its efficiency in case of emergency situations are very important. It’s one thing if you have to dismantle the station yourself and take it to a service center, where examination and repair can take a long time, and quite another if a service engineer is ready to quickly go to your site and, if necessary, replace the necessary part on the spot.
It is also worth paying attention to the presence of all kinds of protections that can prevent the pump from breaking in the event of an accident. First of all, it is protection against dry running, built-in protection against overload of the electric motor and protection against voltage surges, which allows you to power the pump from the mains without using a voltage stabilizer. The soft start function significantly extends the life of the pump and the entire water supply system (always available in installations with a frequency converter).
Finally, you need to pay attention to the energy efficiency class, because electricity outside the city is not cheap.
What models are of interest in the market and why?
– As mentioned above, complete models with built-in automation and a frequency converter are of particular interest today, which allow for comfortable water supply while maintaining a constant water pressure.
Can you provide practical advice to help the user make the right choice?
– As a rule, complete top-end all-in-one solutions with a frequency converter, built-in automation, low power consumption, the longest warranty period and affordable service support turn out to be cheaper, taking into account operating costs, than cheaper, but less reliable and unpretentious ones.
In order not to make a mistake with the choice, contact the manufacturer’s support service, where they will help you choose the best option for a particular situation.
Before choosing a pumping station, do not forget to first assess your needs: the location of the water source, the distance to the house and the slope of the terrain, the number of storeys, the number of water points (including street ones), etc.
