How to choose a pumping station for a private house - rules for choosing a water pumping station

Design features of the equipment

Existing pumping stations differ in design, since models are produced for domestic and industrial use. Powerful devices use wide frames. Models with a protected electric motor are suitable for dachas, but special features are taken into account.

1. Hydraulic accumulator type.
2. Dimensions of the structure.
3. Pressure gauge and other instruments.
4. Volume of the container for storing water.
5. Type of pressure switch.
6. Pumps are installed in the front, however there are exceptions. Surface units are the most common, submersible stations are considered less frequently.

Installation of equipment

A large or small pumping station is delivered to the retail chain assembled, fully prepared for operation. The buyer only has to connect the equipment to the water supply structure and the suction pipeline. Before this, a check valve is installed on the suction pipe - it will hold water in the event of a power outage. A detailed diagram for connecting a pumping station in a private house allows you to do everything yourself.

If there are mechanical inclusions, install a mesh filter. When installing the unit, shock-absorbing material is used to help reduce vibration that occurs during its operation. The installation must be grounded. After the station is fully connected to the water supply, you need to use the filling plug to fill the suction pipeline and the pump housing with water.

After checking the tightness of the connection points, pump up the pressure level through the fitting to the value recommended by the manufacturer. Only after this is the unit connected to the power supply. The room where the station is located must be heated. When placed in a shaft, the lid is made double and insulated.

What is better: a pumping station or a submersible pump?

For autonomous water supply at the dacha, in addition to pumping stations, submersible models are considered and it is necessary to analyze all their features. The first and second options are suitable for supplying water, but the following nuances are taken into account:

1. Distance to the source.
2. Well diameter.
3. Water purity.
4. Pressure level.
5. Pump installations are more common because they demonstrate stable operation. They are more convenient to maintain. Submersible pumps, in turn, are effective in the industrial sector, where water is extracted from deep wells and large volumes are required.

Criteria for selecting pumping equipment

Pumping stations, which are completed directly at the factory, are supplied with a surface hydraulic pump with an ejector, internal or external. In addition, hydraulic accumulators can also be used with submersible pumps, in which case they will be called a “pumping system”.

When using a pumping station, tanks with membranes may have a smaller volume than hydraulic tanks in systems with submersible pumps. This approach is explained by the fact that submersible pumps have fewer starts and stops within an hour than surface pumps.

Selecting a model based on specific characteristics

When a person is faced with choosing a product, he will learn about many characteristics that affect the cost. Manufacturers work according to an individual strategy, but basic indicators are taken into account:

1. Tank size.
2. Water pressure.
3. Operating power.
4. Mains voltage.
5. Water intake depth.

Calculation of pump performance

Before purchasing products, a performance calculation is made. For this purpose, the chemical composition of wastewater and the amount of precipitation are taken into account. An on-site specialist determines the height of the liquid rise. The pump must cope with the increased pressure. In populated areas, this parameter is unstable, so there is a large load on the electric motor. The average model with a power of 1200 watts provides a throughput of 4 cubic meters per hour. If the diving depth is less than 10 meters, 1000 watt equipment is enough. Compact models are produced with an average power of 800 watts.

Maximum water intake depth

Pumping stations are capable of operating in wells of different depths. The standard model is sold with a pumping capacity of up to 10 meters. Sometimes the groundwater level exceeds this mark and more powerful pumps are used. If we consider 800-watt models, they have a throughput of 3.7 cubic meters per hour and draw water from a depth of 9 meters. There are universal models with a pressure of more than 30 meters, their power is 4000 watts, and a productivity of 40 liters per minute is provided.

Hydraulic accumulator tank volume

A hydraulic accumulator tank is otherwise called an expansion tank or a membrane tank. The main task is to maintain stable pressure that is created in the water supply. Automatic stations are produced with various protections; the pressure is shown through a pressure gauge. Problems with pressure surges are often associated with the electric motor. There are devices on the market with hydraulic accumulators with a capacity of 10 liters or more. If we consider an 800 W model, it can use a 20-25 liter tank. More powerful products are equipped with 30 liter expanders. The choice of hydraulic accumulator depends on various factors.

1. Relay operation frequency.
2. Electric motor reliability.
3. Pump activation system.
4. Average pressure in the system.
5. Water compressibility coefficient.
6. Fluid flow rate.

Water pressure in the system

One of the most important characteristics of the product is water pressure. Not everyone is familiar with setting up equipment. Before purchasing, it is important to determine the flange adjustment and learn the principles for eliminating malfunctions. The pressure in the pipeline changes, so the main task is to ensure stable pressure. Mid-price devices provide a pressure of 40 meters. Units with a 20-liter hydraulic accumulator are more productive, much depends on the engine. Considering small wells, a pressure of 25 meters is enough. If we are talking about deep wells (more than 5 m), the figure should be more than 40 meters. When calculating pressure, the following characteristics are taken into account:

1. Hydraulic accumulator volume.
2. Maximum suction depth of the pump.
3. Motor power.
4. Equipment set.

Power and voltage

Manufacturers provide a wide range and there is plenty to choose from. Stations differ in power and voltage, much depends on the area of ​​use. Not only synchronous, but also asynchronous AC motors with voltages of 220, 380 volts and more are presented. Power starts from 500 watts. Various protections are offered, the buyer pays attention to the following features:

1. Rotor winding.
2. Number of phases.
3. Availability of starting devices. If there are problems with the network at the dacha, it is better to use protected stations that are not afraid of short circuits. The most common are pumps with asynchronous motors, with a rated power of 800 W or more. Such models operate at a voltage of 220 volts, they are suitable for pumping clean. You can hope for a capacity of 60 liters per minute and provide a pressure of more than 30 liters.

Unit type and functionality

Stations are classified according to different features. First of all, the type of water is taken into account - it can be clean, slightly polluted, or dirty. Universal models are sold, and consumers evaluate the type of case. Various materials are offered in this regard:

1. Alloy of aluminum and steel.
2. Brass.
3. Stainless steel.
4. Aluminium alloy.
5. Plastic. Models are supplied with a 5 and 25 liter hydraulic accumulator. The pressure parameter depends on the relay. In 2021, users often prefer devices with remote control. There are interesting products from European manufacturers with high-quality centrifugal pumps. Self-priming models are used with or without a filter. Additionally, the devices differ in the size of the connected pipe. The pump is provided with 1, 1.2, 1.5 inch connectors. The hydraulic accumulator is also made of different materials; interesting models with an aluminum or brass tank are offered.

Some tips

Before choosing a pumping station, it is advisable to:

1. Decide on the purpose of purchasing the device, since its power and other parameters depend on this.
2. Perform calculations that are needed for comparison with the technical parameters of the unit.
3. Choose a model according to the advice of experts.
4. Keep in mind that equipment with a metal body has a higher price when compared with plastic models, but it will pay for itself due to a long period of operation and savings on service costs.

The device must be installed according to the manufacturer's instructions.

Rating of the best pumping stations

As mentioned earlier, when selecting a station, many characteristics are taken into account. Due to the large number of manufacturers on the market, users find it difficult to make a decision, so it is recommended to evaluate the rating of the best products. When compiling the TOP, the following factors are taken into account:

1. Maximum power.
2. Immersion depth.
3. Protection of the motor and rotor.
4. Easy to install.
5. Power consumption.
6. Voltage stability.
7. Bandwidth.
8. Price and guarantee.
9. Acceptability of using dirty water.
10. Average performance.
11. Case material.
12. Easy to maintain.

The best pumping stations are presented below.

Top 3 best water supply stations for a private home

When selecting water supply equipment, you should be guided last by its cost. When buying a pumping station, you are not purchasing it for one season or a couple of years. Therefore, the better the quality of water supply stations, the more expensive they are. Do not forget that the stingy pays twice, and a good thing, by definition, is never cheap.

Therefore, we will try to compile a mini rating of pumping stations for the domestic needs of a private home. It takes into account their technical characteristics, durability and user reviews. But, for the sake of comparison, we will choose stations in the mid-price segment, which are quite affordable for the average Russian homeowner.

TOP 5 pumping stations for country houses

If you want to use a pumping station in a country house for permanent residence, then you should choose completely different equipment, which will invariably affect the price offered by the manufacturer.

GILEKS Water cannon PROF 55/90 House - from 25,000 rubles

A relatively inexpensive product from a Chinese manufacturer. Easy to connect and install. The station comes with everything you need. The filter elements are located in the flask and can be replaced without problems. The pump is already equipped with a check valve and is protected from “dry running” by automation. The controls are simple; the program allows you to save factory settings, which are sufficient for the initial period of getting to know the station.

The disadvantages of the equipment include the station’s not very long service life (3-4 years of intensive use), apparently this is due to the use of plastic parts in some components.

VMtec Altera Auto 5/5 - from 27,000 rubles

Consistently high German quality, adapted to Russian realities. Those users who have been using this device for several years note its high performance with the absolute reliability of all components of the station.

If “dry running” protection is also installed in simpler models, then automation, which regulates the operation of the pump depending on the water flow, is a privilege of more expensive models.

Almost all control of the station is carried out automatically and you only have to use the benefits that the equipment provides.
Summary table of characteristics of the VMtec Altera Auto 5/5 station

Wilo HMP 603 1 - from 29,000 rubles

The high cost of the equipment, according to users, is justified only by the reliability of the pumping station. In fact, it turns out that its normal operation will be ensured only by purchasing protection against “dry running”.

If you do not ensure constant pressure at the pump inlet, the automation will not be able to “understand” that there is no water.
Otherwise, the station is an example of equipment for a country house. It is reliably protected from pressure surges, and the membrane tank compensates for hydraulic shocks that are possible when pumping water and several disassemblies. Summary table of characteristics of the Wilo HMP 603 1 station

VMtec Altera Auto 9/4 - from 29,800 rubles

The little-promoted brand of the German company in Russia has characteristics that for the most part belong to more expensive models. And since our users are suspicious of low prices for premium equipment, this provides food for various rumors. For example, some potential buyers refer to some news that the company is buying cheap equipment in China and simply changing the labeling.

It is no secret that many companies locate their production in China, thereby reducing the cost of the final product.
And this move is also used in this pumping station. For quite reasonable money you get high quality, reliable operation of the equipment within the parameters specified by the manufacturer and the ability to automatically control the pump.

Accumulator pressure assessment

For the plumbing in your private home to work properly, the water pressure must be at least 1.4-2.6 atmospheres. In order to extend the service life of the membrane in the accumulator, set the pressure in it approximately 0.2 or 0.3 atmospheres higher than in the water supply.

According to the standard, water supply installed in a private house must have a pressure level of 1.5 atmospheres. This value should be kept in mind if you are setting up a hydraulic tank for operation. If you have a larger home, increase the pressure so that the water can reach the furthest taps in the house, compared to the main riser.

To do this, you should make rather intricate calculations regarding hydraulics, estimate the number and types of plumbing devices you have. However, we can present for you a more simplified and easier formula:

(H+6)/10,

where H is the height from the pump to the water withdrawal point at the highest altitude. If the resulting values ​​exceed the actual values ​​for plumbing fixtures and other household appliances, they will break at this pressure. You will have to choose some other scheme for routing the water pipes.

The best budget models

Inexpensive stations are considered if a pump with low capacity is selected and low water pressure is not required. Manufacturers save on materials and components. However, based on user reviews, it is still possible to select a compact station that will allow you to pump water from a well, and manufacturers from Russia, Italy, and other countries are represented on the market.

Operating principle

A pumping station for a well or well, which ensures the operation of the autonomous water supply system of a private house, operates according to the following principle.

• Water is drawn from an underground source by a pump, after which it enters a hydraulic accumulator, the internal capacity of which is divided into two halves by a membrane.
• The liquid pumped out by the pumping station from an underground source, entering the hydraulic accumulator, acts on its membrane and stretches it, thereby increasing the pressure in the chamber with the air environment.
• As soon as the liquid level in the accumulator reaches its maximum value, the pump automatically turns off and stops supplying water to the tank.
• When the water in the hydraulic tank becomes less than the minimum level, the water pumping station for a private house automatically turns on.

A pump with a hydraulic tank automatically maintains pressure in the home water supply system

For turning the well pumping station on and off, as mentioned above, a pressure switch is responsible, which is pre-set at the factory, but can also be adjusted by the consumer himself. As a rule, a pumping station for a private home is configured by the manufacturer in such a way that it automatically turns off at a system pressure of 3 bar and turns on at 2 bar. To control the level of pressure that an automatic water supply pumping station creates in the pipeline it serves, pressure gauges are provided in the design of such an installation.
