Stations for increasing water pressure: rating of popular models + tips for buyers

Overview of the top best pumping stations

If you are determined to give up daily trips to the well, then it's time to get your own pumping station. By the way, it will allow you to get not only a tap with water, but also a cozy restroom in warmth instead of a cold booth on the street. It remains only to choose a good pump and install it. Of course, you will have to deal with the installation yourself, but we will help you with the choice of a reliable water supply system. That is why we have compiled the top 10 best pumping stations in 2020.

And which of these would you prefer?

How does it work

These are the parameters at which the relay will give commands to turn the pump on and off.

The battery tank will smooth out the switching peaks.

The algorithm of the entire installation will be as follows:

• according to the "Technical Instructions for the Installation", the first start-up is carried out;
• the pump fills the accumulator tank (damping tank) 4, through the suction pipe 5, up to the maximum pressure value;
• when it is reached, the automatic pressure switch turns off the pump motor;
• during the analysis of water, through the pressure pipe 1, there is a pressure drop in the accumulator 4 to its minimum values;
• automatic pressure switch turns on the pumping station;
• the cycle of work is repeated again.

The larger the volume of the damper tank and the greater the difference between the extreme pressure values ​​​​set on the control relay, the less often the unit will turn on. Due to the pre-set pressure in the accumulator, the water supply will be stopped only in case of emergency.

Expert advice: with a good debit (replenishment) of water in the source, it is possible to install an additional damper tank.

Install a pressure switch

The pressure switch is installed immediately after the pump

The following recommendation is related to work, directly with the liquid supply pumping station itself. According to the technical parameters, the unit can produce a maximum fixed pressure. Usually it is 3-5 atmospheres. In our case, the Grudnfos MQ 3-45 station produces 4.5 atmospheres.

If water is pumped from a storage tank, the pressure in the pipeline will also be 4.5 atmospheres. In the case of abstraction from the main water supply systems, the situation is slightly different. Water from the main pipeline is supplied under different pressure. If the pressure in the water supply jumps to 3 bar, plus the station's capacity of 4.5 bar, the result will be about 7 bar. In any case, such an indicator will have a very negative impact on the operation of the entire piping system in the room. Butt joints of fittings, pipes themselves and other important structural elements may be damaged.

To prevent this from happening, a pumping station pressure switch must be installed at the outlet of the pumping station. That is, at the inlet, for example, 7 bar, after passing through the pressure switch, you get 4 bar (if you set this value), which is necessary for the normal operation of the entire system. The device of the regulator itself provides for the possibility of adjusting the water pressure for specific operating conditions. As a result, as soon as the station reaches the set 4 bar, the relay gives a command to turn off the pump.

What to look for when buying?

The first thing you need to pay attention to before buying is power. In different models, it varies in the range of 0.6-1.5 kW

For a small room, a unit of 0.6-0.7 kW is suitable, for medium-sized ones with several water intake points - 0.75-1.2 kW, for spacious and dimensional houses with household communications and an irrigation system - 1.2-1.5 kW .

Throughput matters a lot. The larger it is, the more convenient and easier it is to use the home plumbing system. But the indicator of the station should not exceed the capabilities of the well, otherwise there will definitely be drops in the work.

For a small country house, where the owners are regularly located only in the summer season, and in autumn and winter they appear from time to time, a station with a capacity of up to 3 cubic meters per hour is enough. For a cottage of permanent residence, it is worth taking a model with an indicator of up to 4 cubic meters / h.

We also recommend reading our other article, where we talked in detail about how to choose a pumping station for a summer residence.

If you need to connect an irrigation system to communications, it is recommended to consider devices that can pass up to 5-5.5 cubic meters / h through themselves.

The volume of the internal water storage tank in standard stations ranges from 18 to 100 liters. Most often, buyers choose tanks from 25 to 50 liters. This size is considered optimal for a family of 3-4 people. If friends or relatives often come to visit, it is worth taking a more spacious unit.

The body material is not particularly important. It is possible to use pumping stations integrated into technopolymer blocks. They will cost significantly less. For a steel case with an anodized coating, you will have to pay an additional amount, but on the other hand, the station will be located not only in the house, but also on the street.

The sound background of the work is of great importance.For placement in residential premises, you need to look for the most quiet devices that do not interfere with a comfortable stay. More powerful units that sound loud should preferably be placed in basements or outbuildings, where their noise will not annoy anyone.

How to choose a pumping station

What pumping station for at home will be better depends on the required water quality, throughput, suction depth and power consumption.

Water quality

Pumping stations are not designed for heavily polluted waters

If the supply will be from a well or storage tanks with a low concentration of impurities, you should pay attention to models with a preliminary cleaning filter. They must be designed for a maximum solids content of 150 g/cu.

m. When using a relatively clean liquid, pumps that pass 50 g / cu. m.

Bandwidth

For irrigation of a plot of 600 sq. m, providing water supply or increasing pressure in a small country or private house, a capacity of 2 to 3.6 cubic meters is sufficient. m/h In the case of a larger area or residence of more than 4 people, it is worth choosing models with a capacity of 4 cubic meters. m/h

Immersion / Suction Depth

Models cope with liquid suction from a depth of up to 9 m with built-in ejector

If the immersion depth exceeds this indicator, you should pay attention to more expensive units with a remote option, operating at a depth of up to 35 m

Power consumption

To obtain a throughput of 2.4-3.6 cubic meters. m/h at a pressure of 36 to 45 m is sufficient power consumption of 450 to 800 watts. If there is a need for more performance (4.5 cu.m / h), then a 1100-1300 W motor would be a good option. It provides a head of 48-50 m.

What is a pumping station for a residential building

This is a compact device that, through automatic control, ensures the operability of an autonomous water supply system in a private house.

The pumping station includes:

• suction pump;
• pressure tank;
• pressure switch;
• manometer.

It can be installed next to the well:

• in the basement;
• in a specially designed room;
• in mine.

High-quality equipment does not require special maintenance, reliable in operation.

What is a pumping station for?

The installation of a household pumping station in cottages, summer cottages and country houses that use water from their own wells, wells and other sources, raises water consumption to a higher level.

It becomes possible to have an autonomous water supply system, which will increase the comfort of living. Conditions are being created for connecting sanitary cabins, washing machines and dishwashers.

Principle of operation

The operation of the pumping station is carried out using a pump, a hydraulic accumulator and an automation system that regulates pressure. When the unit is started, water begins to be pumped into the pressure tank (hydraulic accumulator) and further through the pipeline.

When the upper pressure limit is reached, the pump is switched off. Further, the flow of water to the consumer is carried out due to the pressure in the accumulator, until it reaches the lower limit. Then the pump starts up again.

This ensures a constant supply of water. The change-sensitive pressure switch is set at the factory.The pressure value is 2 bar to start the pump and 3 bar to stop. Control is carried out using a manometer.

What it is

1. How is the pumping station set up?

It is a complex of equipment mounted on a common frame, including:

• Centrifugal surface pump;
• Membrane hydraulic accumulator;
• Automatic relay for turning on the pump with a pressure sensor.

Station device

The price of a pumping station depends on the power of the pump, the volume of the accumulator and varies from 5 to 15 or more thousand rubles.

The device works like this:

• When power is applied, the pump pumps water into the membrane tank. The pressure in it rises to the upper limit of the automatic relay setting and is maintained by air compression in the air compartment of the accumulator;
• As soon as the pressure in the tank of the pumping station reaches the upper value in the relay settings, the pump turns off;
• When water flows through plumbing fixtures, the pressure is provided by air compressed in the accumulator. When the pressure drops to the lower limit of the relay setting, it turns on the pump, and the cycle repeats.

A special case

In the vast majority of pumping stations, the suction of water is provided only by the vacuum created in the suction pipe. Accordingly, the theoretical maximum suction depth is limited by the height of the water column at an excess pressure of one atmosphere - 10 meters. In practice, for devices on the market, the suction depth does not exceed 8 meters.

Calculation of the height of the water column for an overpressure of one atmosphere

Meanwhile, the so-called two-pipe stations with an external ejector are capable of lifting water from a depth of 25 meters or more.

How? Isn't that against the laws of physics?

Not at all. The second pipe descending into the well or well supplies water to the ejector with excess pressure. The inertia of the flow is used to entrain the masses of water surrounding the ejector.

How is the pumping station

The complete set of pumping stations, most often, includes:

• Pump unit.
• Pressure tank with membrane.
• Pressure switch.
• Manometer, for measuring pressure.
• Cable.
• Terminals through which grounding is performed.
• Connector for connecting a device.
• Sometimes this includes a storage tank or a hydraulic accumulator.

When installing a storage tank in the station, there are a number of disadvantages:

• Low water pressure.
• Difficulties in installation.
• Large dimensions.
• Installation of the tank requires higher than the level of the room.
• If the sensor fails, if the tank is filled with water, it may cause flooding of the room.

A station in which the accumulator is equipped with a pressure switch has fewer disadvantages. A special relay monitors the upper limit of air pressure. The pump will stop working when the set pressure value is set, and when a signal is received on the low pressure limit switch, the unit will start its operation again.

Automatic pumping stations respond to the inclusion of a water tap. The pump is running when opening a faucetand when it is closed, the unit will automatically turn off.

How to choose a pumping station

In the absence of a centralized water supply in the house, it will be quite difficult to do without a pumping station.

When choosing equipment, consider:

Performance. It is necessary that this volume of liquid is enough for the needs of all the inhabitants of the house.

1. centrifugal self-priming pumps;
2. vortex self-priming pumps.

Both types can be:

1. monoblock, when the pumping station has a hydraulic part of the pump located on the same shaft with an electric motor;
2. console.

There are pumping stations

1. the first lift, which is performed from a well or well;
2. second, it creates in the system a pressure value that is above the level of the earth's surface: the second, third floors;
3. less often than the third, used to raise water even higher. In this case, several pumps work in one chain.

The most popular are pumping stations using a self-priming pump.
To meet the needs of a dwelling where up to four people live, usually a pumping station of small or medium power is enough, with a capacity of up to 20 liters with a capacity of up to 4 m3 per hour and a pressure of 40 to 55 meters.
When purchasing equipment, it is necessary to pay special attention to the material of manufacture of the unit parts and the quality of its assembly.

One of the most important criteria for most people when choosing a pumping station is its price, while many do not think about the fact that often a miser pays twice.

• There are also summer residents who prefer to assemble something from the category of a combined hodgepodge from improvised materials. As a result, the elements that make up such a makeshift system are so unpredictable that they are likely to quickly render it unusable.
• Another option for economical ones is to purchase the cheapest Chinese pump. Such devices have a body made of thin low-quality plastic, as well as dubious components.
  These pumps are the cheapest and lightest, but they cannot distinguish more advantages, but there are enough disadvantages. They are noisy and have a short lifespan.

If we single out pumping stations according to the average ratio of price and quality, then their cost will not exceed $400. Better models cost about 500.
