Pumping station for a private house: characteristics and instructions
In this article you will learn what a pumping station for a private house is, its purpose, design and operating principle of a pumping station in a private house. And at the end of the article there will be top pumping stations for a private home.

Pumping station - what is it, its purpose. Methods of water supply at home
Residents of private houses and summer cottages suffer from insufficient water supply. The autonomous system is not enough to supply a residential building, vegetable garden, or garden. There are three ways to provide water to a room:
- The pump is connected to the consumer
- Storage tank and pump
- Pumping station with hydraulic accumulator
In the first case, the pump pumps water from the source, but its power is often not enough, so the pressure in such a system is usually low.
In the second case, the pump pumps water from the source into a separate container, from where it is used by the consumer under pressure. The disadvantage of such systems is their long operation.
Let's look at the third method in detail.
A pumping station is a set of devices, a system for supplying water to a room. The pumping station increases the pressure in the pipeline.
Design and principle of operation of the pumping station
A classic pumping station with a hydraulic accumulator consists of 5 parts:
- Hydraulic accumulator
- Centrifugal pump
- Electric motor
- Pressure gauge
- Pressure switch
Some models additionally include a filter to protect the device from sand, silt, rust and other contaminants.
The electric motor is connected directly to the pump by a shaft. The pump is connected by a pipeline to a water supply pipe, a water outlet pipe and a hydraulic accumulator. Also connected to the pipes is a pressure gauge to measure the pressure inside the pipes and a pressure switch.
How does a pumping station work?
An electric motor rotates the pump. The pump pumps water from the source. Water fills the entire volume of the system - the internal volume of the pump, the pipes between the pump and the consumer, the internal volume of the hydraulic accumulator. The hydraulic accumulator consists of a housing, a membrane of an air area and an area for water. The liquid fills the internal volume of the accumulator by a third and begins to put pressure on the membrane, compressing the gas inside. Gas is pumped in at the plant. The gas itself puts pressure on the water and tries to push it out. The pump pumps water into the system all this time. To turn off the pump, a relay is installed in the station; it is installed near the motor and a water outlet pipe is connected to it. The device consists of two springs/pistons, contacts, a membrane and a flange. The liquid fills the flange with the membrane and presses on the latter. When it presses hard enough on the membrane, the latter presses on the piston, which opens the contacts - electricity does not go to the motor, the pump stops pumping water.
You open the tap - the accumulator membrane pushes out water, its quantity in the system decreases, and the pressure decreases. The liquid does not press enough on the relay membrane, the piston lowers, and the contacts close - electricity is supplied to the motor, and the pump turns on. It pulls water from the source into the system until the pressure rises again to open the contacts.
Rating of the best pumping stations for the home with characteristics
1.KARCHER BP 5 Home
The first place is occupied by a model from the global German manufacturer – KARCHER. The device is distinguished by its build quality, ease of use and ease of installation. The model has a low noise level during operation. The station only works with clean water. The device is intended for domestic water supply, therefore it is not recommended to use KARCHER BP 5 Home for industrial or semi-industrial purposes. Black color with a yellow engine attracts with its appearance. According to characteristics:
- Weighs 14.7 kilograms
- Operates at 220 Volts (±5%)
- Thread – diameter 1
- Installed horizontally
- The volume of the hydraulic accumulator tank is 24 liters
- Maximum head 50 meters
Advantages of the device:
- Comes with check valve
- Built-in self-monitoring and operation indication system
- Self-off/on function
- Provides protection against overheating, power surges, dry running, overload
- Stainless steel tubes
Minuses:
- Short network cable (1 meter)
- You cannot turn on/off the device yourself
2. PATRIOT R 1200/24 INOX
The classic pumping station from PATRIOT takes second place in the rating of pumping stations for a private home. Dry, pure green design. The body is made of stainless steel. The device can also be installed in rooms with high relative humidity. It vibrates and makes a lot of noise - we recommend placing the unit in a box or soundproofing the room with the station. The model is designed for domestic needs - it will cope perfectly with supplying water from wells and wells. There is nothing special to say about the device, except that it is a high-quality, reliable, powerful and standard pumping station for pumping water. Characteristics:
- Weighs 14.4 kilograms
- Operates at 220 Volts (±5%)
- Thread – diameter 1
- Installed horizontally
- The volume of the hydraulic accumulator tank is 24 liters
- Maximum head 30 meters
Advantages of the device:
- Housing protected from moisture and corrosion
- 24 liter tank
- High performance motor/pump
- A pressure switch is used for adjustment
Minuses:
- Not protected from dry running
- Small maximum pressure
3. Bison ZNAS-1200-S
The Zubr device will provide stable water pressure to a small country house. This automatic pumping station with filter and accumulator is distinguished by its size and high performance. The device is designed for small household needs - garden, small vegetable garden, residential building. The device is fully automated - it independently maintains pressure in the pipeline. In this case, the hydraulic accumulator tank can be interrupted/filled more than 10 times daily. The Zubr ZNAS-1200-S pump can pump water from a depth of up to 30 meters and supply two-story houses with it.
Characteristics of Zubr ZNAS-1200-S:
- Weighs 13.2 kilograms
- Operates at 220 Volts (±5%)
- Thread – diameter 1
- Installed horizontally
- Hydraulic accumulator tank volume 20 liters
- Maximum head 50 meters
Pros of the unit:
- The kit includes a check valve
- Pumps water from a depth of up to 30 meters
- Raises water to the second floor
- There is protection against dry running, power surges, and overheating
Disadvantages of the device:
- Gaskets wear out within two years
- Problems often arise during station installation
