Rating of the TOP 16 best pumping stations for a dacha and private home: which one to choose, characteristics, manufacturers, pros and cons

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.

Silent water supply pumping stations for a private home

Modern technologies do not stand still, which makes it possible to purchase technological innovations now that guarantee quiet operation and longevity of the equipment. It is worth understanding that the degree of noise from it also depends on the correct choice of equipment.

New generation pumping stations are made in such a way that the operation of the motor is almost inaudible, but as a rule, such a product costs a lot of money. Even if you buy such a station, after some period of time it will have to be repaired, and this will also cost a pretty penny. Today there is a large choice and everyone decides for themselves what is best for them.

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.

Choosing a place in the country to install a pumping station

It is important in advance, even before purchasing a pumping station in a store, to decide on the location of its installation. The size of the site and distance from the house or water source can play an important role when choosing a unit. There are three options for installing a pumping station:

• in close proximity to a water source (well or well);
• directly in the premises of a country house (only quiet station models are suitable);
• in utility garden rooms on a summer cottage.

Attention! With any chosen option, if the pumping station will be operated in winter (at negative air and ground temperatures), it is necessary to lay the pipes of the water supply system into the ground below its freezing level, and insulate the places where they exit the ground and enter the house. The pumping station can only be used in winter if it is installed in a heated room. If you do not use your dacha in winter, before frost sets in, the pumping station must be completely dismantled and moved indoors. In the latter case, the remaining water must be drained from the station.

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.

Making a soundproof box for a pump with your own hands

To make your own box for the pump, you must first take its exact dimensions. It is worth taking into account not only the actual dimensions of the unit, but also making a small allowance for the thickness of the insulating material. For the body itself, it is best to use wooden materials. Wood absorbs sound well and is easy to process. You can use plywood, chipboard or MDF panels, it all depends on material capabilities and personal preferences.

@Nasosnaya_stancia

The box must be assembled so that it forms a door for periodic inspection of the device. It is clear that if there is a door, then it needs seals to prevent any noise from passing through. Today in the construction market you can select the most suitable sealing materials in terms of thickness, structure and cost.

You can connect the box to the insulating layer using a construction stapler, which will significantly save time and effort. It is also important to use high-quality fittings in your work, because the service life of the protective box depends on this. All elements of fastenings and curtains must work correctly and easily, so that you do not have to redo everything soon.

@Nasosnaya_stancia

The inside of the box is protected with fibrous sound insulation, and on the outside the box can be covered with sound-absorbing gypsum boards. The weight of the entire structure will increase, but comprehensive sound insulation will also become noticeable. Another little tip for making a box: the legs or stands on which the box will be installed must be equipped with rubber inserts that can prevent vibration sounds.

Options

In fact, all pumping stations are industrial or domestic. Industrial ones are characterized by high power and productivity, as well as mechanical strength. For the household consumer, the latter are more interesting, since they are the ones who work tirelessly on summer cottages and in private houses. The selection of a pumping station should be made according to the following criteria:

Technical specifications

• Power, W);
• Productivity (m3/hour);
• Maximum water level rise (m);
• Hydraulic accumulator volume (l);
• Water intake height;
• Dry running protection;
• Overheat protection;
• Type of pump installed (horizontal, vertical, axial, centrifugal or diagonal);

Location

• Ground (overground) station;
• Partially buried station;
• Buried station.

Control method

• Manual control;
• Automatic control;
• Remote control.

Now let’s look at the technical parameters of the stations in more detail:

1. The power of
   a pumping station for domestic use, which is of course suitable for a summer house or private house, is on average from 600 W to 1.5 kW.
2. The second important indicator is productivity
   , which is not always directly proportional to power and can be from 3 to 6 m3 per hour.
3. The maximum rise of water
   is of great importance, for example, if you have a bathroom on the second floor of the house, then this parameter should be taken into account as one of the main ones when choosing a pumping station for your dacha.
4. The volume of the hydraulic accumulator
   affects the frequency of operation of the pump. And the frequency of operation is inversely proportional to the service life of the automation and in particular the on/off relay. To extend the service life, you need to correctly select the volume of the hydraulic tank. And here there is a direct dependence - the more people live in the house, the larger its volume should be. So for one person a volume of 24 liters is quite enough, for 2-4 people - from 50 liters or more.
5. Water intake height
   is the height from which the station is capable of lifting water in operating mode. Here, in addition to the distance from the ground to the water surface, the total horizontal length of the hose or pipe to the station itself should also be taken into account.
6. Dry-running protection
   - not a universally available option, is designed to automatically turn off the pump if there is no water in the well or borehole - a useful feature if your water source is not stable. Present in more expensive models.
7. Overheat protection
   helps prevent damage to the electric motor by turning it off in time.

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.

Water consumption, productivity, pressure

Before buying a pumping station, you should understand whether this model will be able to meet your needs, whether it can function normally in the specific conditions you have. This can be assessed by a number of technical characteristics of the pump. Particular attention should be paid to such parameters as the created pressure (the height to which the pump is capable of raising water) and its performance (the volume of water pumped per unit of time).

The total water consumption of a home is the total water consumption of all household appliances (dishwasher and washing machine) and other water distribution points (taps in the kitchen and bathroom, drain in the bathroom, filling the pool, automated watering and irrigation systems on the site, etc.).

Ideally, the station’s productivity should be no less than the sum of the costs of all water points in the house. Only in this case, the residents of the house will not experience problems with the water supply and its pressure. Only in this case will they be able to open the tap without thinking that someone in the house may need water more at the moment.

As a rule, fairly powerful pumps easily supply up to 3.5-8 m3 of water per hour, maintaining a pressure of 2-3 bar in the water supply network.

To determine the power of the pumping station required to provide water to all water points, three parameters should be assessed.

1. Firstly, you need to know the height of the supplied water, i.e. calculate the distance from the water surface to the highest point of the water pipe.

2. Secondly, you should take into account the operating pressure in the water supply (for normal operation of household appliances and optimal water pressure in taps, the pressure is required to be at least 2 bar).

3. Thirdly, it is necessary to estimate the pressure loss along the entire length of the water pipeline.

Calculating water consumption and the required pump performance, as well as selecting a specific pumping station that meets these criteria, is the task of specialists. You are also required to determine in advance the distance from the water intake pipe of the pump to the water surface in the well vertically and the distance of the pumping station from the well, to know the type and diameter of the pipes used.

It would be a good idea to prepare a site and house plan indicating the location of all water points.

There is one more important point that should be taken into account before choosing a pumping station for your garden or home. Whether you pump water from a well or from a well, it doesn’t matter, but the filling capacity of the source, i.e. its ability to “generate” water should not be less than the station’s productivity.

The flow rate of a well can be found out from its passport issued by the organization that carried out the drilling.

The best premium models

If your budget allows, you can consider premium stations. In the high price category there are sellers of German and Italian manufacture. The user has the opportunity to select an installation with a protected cable and a powerful pump. There are models with electronic control and LCD display.

Types of pumping stations and distance to the water surface

There are pumping stations with built-in and remote ejector. The built-in ejector is a structural element of the pump; the remote ejector is a separate external unit immersed in the well. The choice in favor of one option or another depends primarily on the distance between the pumping station and the water surface.

From a technical point of view, the ejector is a fairly simple device. Its main structural element - the nozzle - is a pipe with a narrowed end. Passing through the narrowing point, the water acquires a noticeable acceleration. In accordance with Bernoulli's law, an area of ​​low pressure is created around a flow moving at an increased speed, i.e., a rarefaction effect occurs.

Under the influence of this vacuum, a new portion of water from the well is sucked into the pipe. As a result, the pump spends less energy to transport liquid to the surface. The efficiency of pumping equipment increases, as does the depth from which water can be pumped.

Pumping stations with built-in ejector

Built-in ejectors are usually placed inside the pump housing or located in close proximity to it. This allows you to reduce the overall dimensions of the installation and somewhat simplify the installation of the pumping station.

Such models demonstrate maximum efficiency when the suction height, i.e., the vertical distance from the pump inlet to the water level at the source, does not exceed 7-8 m.

Of course, you should also take into account the horizontal distance from the well to the location of the pumping station. The greater the length of the horizontal section, the shallower the depth from which the pump is capable of lifting water. For example, if a pump is installed directly above a water source, it will be able to lift water from a depth of 8 m. If the same pump is removed from the water intake point by 24 m, then the depth of rising water will decrease to 2.5 m.

In addition to low efficiency at large water depths, such pumps have another obvious drawback - increased noise levels. Added to the sound from the vibration of a running pump is the noise of water passing through the ejector nozzle. That is why it is better to install a pump with a built-in ejector in a separate utility room, outside a residential building.

Pumping stations with a remote ejector

A remote ejector, which is a separate small block, unlike a built-in one, can be located at a considerable distance from the pump - it is connected to the part of the pipeline that is immersed in the well.

Remote ejector.

To operate a pumping station with a remote ejector, a two-pipe system is required. One of the pipes is used to lift water from the well to the surface; along the second, part of the raised water returns down to the ejector.

The need to lay two pipes imposes some restrictions on the minimum permissible diameter of the well; it is better to provide for this at the design stage of the device.

Such a design solution, on the one hand, allows you to significantly increase the distance from the pump to the water surface (from 7-8 m, as in pumps with built-in ejectors, to 20-40 m), but on the other hand, it leads to a decrease in the efficiency of the system to 30-30 m. 35%. However, once you have the opportunity to significantly increase the depth of water intake, you can easily come to terms with the latter.

If the distance to the water surface on your site is not too deep, then there is no need to install a pumping station directly near the source. This means that you have the opportunity to move the pump away from the well without a noticeable decrease in efficiency.

As a rule, such pumping stations are located directly in a residential building, for example, in the basement. This ensures increased equipment service life and simplified system setup and maintenance procedures.

Another undoubted advantage of remote ejectors is a significant reduction in the noise level produced by a working pumping station. The noise of water passing through an ejector installed deep underground will no longer disturb the residents of the house.

Material of manufacture of the pump and its structural elements

The main disadvantage of centrifugal pumps is their high demands on the purity of the pumped water. Grains of sand, silt and other solid particles that get inside cause premature wear of pump parts.

The service life of the equipment largely depends on the material from which the impeller is made. Stainless steel impellers are more durable, but are more expensive than plastic products, often installed in household models.

Various materials are also used to make the pump housing.

1. Pumps in plastic cases are the cheapest and, importantly, the quietest. However, such pumps are not reliable.

2. Steel, on the contrary, is the most expensive and noisy, but at the same time the most durable.

3. Cast iron ones occupy an intermediate position in all respects.

In addition to the material used to make the pump housing and its impeller, when selecting, you should pay attention to one more parameter, namely the material of the electric motor winding. Often, aluminum winding is used to reduce the cost and lighten the design.

Unfortunately, it is less durable than copper, which negatively affects the overall reliability of the pump, which is forced to work year-round and almost around the clock.

Optional equipment

In addition to the electric pump, hydraulic accumulator and control automation, the kit of any pumping station must include:

• connecting fittings, including flexible hoses connecting the pump to the hydraulic accumulator;
• a pressure gauge that measures the fluid pressure in the system and facilitates monitoring the operation of the pump,
• check valve that prevents the supply line from emptying when the pump is turned off;
• filters that prevent mechanical impurities from entering the pump;
• pump safety shutdown circuit breakers.

Filters

Centrifugal pumps are characterized by increased demands on the purity of the pumped liquid. It is very important that the water passing through the pump does not contain abrasive particles (silt, sand, etc.), as well as long-fiber inclusions with linear dimensions of more than 2 mm (algae, blades of grass, wood chips).

The maximum permissible amount of mechanical impurities is considered to be 100 g/m3. A coarse mesh filter will help protect the pump from failure and its individual components from premature wear as a result of pumping water containing foreign inclusions.

It is mounted at the end of the water intake pipe and cuts off large debris floating in the water column or on its surface.

After the station, fine cartridge filters are installed to further purify the water, which is sent to the consumer. However, they no longer have anything to do with the pumping station.

Check valve

In order for the pump to be able to start pumping water at any time, it is necessary that the supply line is always full. That is why the water intake system of pumping stations is equipped with a check valve installed immediately after the coarse strainer.

The presence of a check valve will save you from having to wait a long time each time for water to rise into the pump from the well, and, more importantly, it will protect the pump from operating in a “dry” start-up mode, which is fraught with equipment failure.

Protective automation

Our power grids cannot boast of stability, and the voltage often fluctuates over a fairly wide range. A residual current circuit breaker will help protect expensive equipment from power surges. If your station does not include this component, you can (and should!) purchase it separately. It would also be useful to have a safety shutdown circuit breaker when the pump overheats.

The dry-running protection system is another element that is necessary to extend the service life of the pumping station. It is especially important in cases where the productivity of the well is variable. A sensor placed in the well will signal to turn off the pump as soon as the water level drops below the minimum limit. This will prevent overheating and pump failure due to pumping air.
