Pumping station for a private house: how to choose and what to look at before buying

Remember how much time, effort, and sometimes nerves takes the banal supply of suburban property with water. Try to transfer a considerable amount by hand to the points of drawing and do not get tired. And if you still need to fill the tanks for irrigation of the garden / kitchen garden, the pool and tanks in the bathhouse, then it is easier to completely abandon the undertaking than to realize it. Truth?

It is quite another matter if instead of you such a laborious process is carried out by pumping equipment. Tireless "workers" will provide all objects with water extremely quickly. Therefore, a pumping station for a home or adorable summer cottage is simply necessary. And how to choose it, we will describe in detail in the next article.

The information we have proposed in the finest details illuminates the nuances of the device and the principle of the system. Your attention is presented to the selection criteria of the unit and the most popular models. The information we proposed is backed up by useful schemes, photos and videos.

Choosing the best option for water supply

An own source in a suburban area can fully provide water to a residential building, a house adjoining territory, a kitchen garden, and a garden.

To create an uninterrupted, well-functioning water supply system, it is necessary to think over the supply process, i.e. choose a pumping station to pump liquid from a source to a house or to other points of a tapping and to lay communications.

There are three generally accepted methods for transmitting water:

• pumping directly to the consumer;
• use of storage tank and pump;
• application accumulator and pump.

The pump connection diagram is considered to be the simplest, since water is supplied directly from the well to the place of use - a kitchen tap, watering hose, etc.

When choosing equipment for connection, it is necessary to carefully study its technical characteristics and ensure the availability of a power source. Frequent activation (if automation is provided, then each time the valve is opened), the pump quickly breaks down.

An example of installing a surface pump with which watering lawns, flowerbeds, beds is carried out. To ensure garden water supply, an average power model is enough

A pump without additional equipment is good for small summer cottages that are visited in the warmer months or visit occasionally, for example, on weekends.

The second option is characterized by the presence of a storage tank - a tank installed in the upper part of the building (most often in the attic).

The advantage of this design is the water supply equal to the volume of the tank. Even during power outages, you can freely wash the dishes or take a shower.

Cons of a similar design:

• a prerequisite is the presence of an insulated attic sufficient to install the tank area;
• the large size of the tank is important, so it will be necessary to strengthen the floors;
• in case of an accident, high-quality waterproofing should be done.

Additional costs are sometimes required to purchase a second pump. It is necessary to maintain certain pressure parameters.

The more mechanisms, the more complex the system and the higher the likelihood of failures during operation.

Comparative scheme of two options for water supply at home: 1 - with a submersible pump and storage tank, 2 - with a pumping station that supplies water from the well

The third option is the most acceptable for those who constantly live outside the city and want to improve their home to the maximum.

The hydraulic accumulator provides the building and other objects of consumption with the necessary amount of water, creating the necessary pressure. In addition, two principles that are critical to technology are respected - cost-effectiveness and high productivity.

The principle of the pump station

The pumping station can be purchased ready-made or assembled independently from the components: pressure tank, (submersible pump or surface type pump), pressure switch and automatic control unit.

Experts recommend staying at the finished pump station, in which all the elements are ideally suited for each other in terms of technical characteristics, material and size.

Submersible pump with filter and check valve can be replaced with a surface model - both options have their advantages.

The filter is necessary to protect communications from the ingress of sand lying on the bottom and suspended impurities, the check valve prevents the outflow of water in the opposite direction when the unit automatically shuts down.

The shutdown occurs on the signal of the pressure switch, which is activated when the pressure reaches the maximum mark. As soon as the liquid in the accumulator tank becomes smaller, the pressure stabilizes, the mechanism turns on again and begins to pump water.

For the station to work, 220 V electric power is required. The pipe cross-section must be selected so that the water moves freely through the channels connecting the pumping equipment and the consumption points.

Powerful equipment can provide water for a building in which a family of 5-6 people lives, and water points outside the house (in the garage, in the summer kitchen, in the vegetable garden or garden).

Model selection for specific characteristics

The variety of models on the market is explained by the fact that the conditions for connecting can be completely different: one option is necessary well pumping station (with a surface pump installed in the caisson), others need a submersible mechanism or a more powerful model with an ejector that can pump water from the well from a depth of 20-25 m.

When choosing pumping equipment in a store, the properties of the samples provided must necessarily be compared with individual requirements.

Pump performance calculation

There are difficulties with calculating performance, because many do not know what to start with. In fact, for objective calculations, several factors should be considered.

For example, it is important to take into account the volume of the well lowering - a one-time water intake at zero flow rate, the rate of restoration of the volume of liquid in the source, the mode of active operation of the water supply system, etc.

To find out the average, enough data for 1 day. This is possible because of the complete restoration of the volume of water in the well in 5-6 hours (the time when the liquid is not consumed at all).

The busiest “peak hours” are time periods when the bathrooms are actively used or the garden is irrigated. They are most suitable for the objectivity of the calculations.

For the calculation, it is necessary to add together the parameters of all consumption points, not forgetting the correction factor, to derive the productivity unit - l / min or l / hour

Suppose a well has a flow rate of 200 liters and a decrease volume of 50 liters. If there is a succession of taking a bath (200 l each) by three family members, and we need water to flow freely to other points of tapping, the productivity should not be lower than 300 l / h.

Sometimes the calculation is made based on the amount of water consumption by all family members or by calculating the maximum water use - peak consumption.

It is assumed that at the same time all water points are involved, the average consumption of which is:

• washbasin faucet - 0.1 l / s;
• kitchen mixer - 0.15 m / s;
• drain tank - 0.1 m / s;
• shower - 0.25 l / s;
• washing machine - 0.3 l / s.

The maximum possible productivity is considered to be 800-1000 l / h (or more), but not every well has such a water supply and a high recovery rate.

Maximum water intake depth

To find out this parameter, you need to know exactly the size of the well (well) and measure the distance from the installation site of the accumulator to the source.

The main value is the height from the water surface to the axis of the pump installed near the well or well. If the station is located at any distance, for example, in the basement of a house, then the horizontal section must also be kept in mind.

When making calculations, one should rely on the value of not a static, but a dynamic level - the average indicator with regular liquid intake for 1-2 days

There is an error correction due to the resistance exerted by the pipes, non-return valve and filters. This means that it is necessary to add another 15% to the amount received.

By the way, the resistance of stainless steel pipes, which is used less and less, is much higher than that of plastic communications.

The vertical arrangement of pipes refers to the horizontal in a proportion of 1:10. For example, the distance to the installation site of the accumulator is 20 m, the depth of the well to the water mirror is 8 m, therefore, equipment with a minimum sampling depth of 8 m + 20 m is necessary: ​​10 = 10 m

Accumulator tank volume

When choosing a pumping station for a private house, do not forget to ask about the volume of the accumulator, since the full supply of water depends on the size of the tank. The larger the tank, the more space the equipment takes and the more expensive the entire installation is.

It is believed that large tanks have rarer on / off cycles, which is why their life is significantly increased.

Gileks Jumbo pumping station with built-in ejector and automatic control: power - 1100 W, accumulator capacity - 24 l. Suitable for use in wells and wells

For a single tenant or couple, a volume of 24-30 liters is enough. A small tank is appropriate when the need for water supply occurs periodically, for example, on weekends.

A volume of 50 liters is an average capacity suitable for serving a group or family of 3-5 people who are constantly living in a country house. For housing, uniting more than five people under its roof, equipment with a 100-liter tank should be purchased.

Tanks of less than 24 liters are irrational to buy, since they quickly wear out, respectively, have a short service life.

The water pressure in the system

The functioning of the system will be complete and comfortable only if at each point of water consumption there is a sufficient pressure of water. It means that network pressure provides uninterrupted, correct giving.

For example, for a kitchen faucet, a pressure of 1 / 1.5 atmospheres is enough, which equals 10/15 m water column. More serious equipment requires increased parameters.

Grundfos JPBasic2 PT pump station with a power of 600 W and a maximum pressure of 42 m. The purpose is to increase the pressure in domestic systems, watering summer cottages or gardens

The value of the water pressure can be found in the instructions. Units with a maximum pressure of 45-50 m can be equally well used both in country cottages and in small enterprises.

They have increased productivity (up to 4500 l / h) and are often equipped with an additional storage tank

Power and voltage

Installation power and supply voltage are necessary for proper connecting pumping station. The standard power supply voltage - 220 V - is typical for most household pumping stations, since single-phase AC networks are much more common.

A voltage of 380 V is necessary for the high-performance functioning of equipment on an industrial scale, and in the residential sector it can be found only in multi-storey buildings.

The Parma model SN-600P is equipped with a self-priming pump and is used to supply water to a house or to a personal plot from a tank, pool or well. AC voltage - 220 V, power - 600 W

The power of domestic installations with a hydraulic accumulator is from 600 to 2000 watts. It affects the choice of protective devices and power cable. If there is overheating, short circuit, dry run start, modern models are automatically turned off.

Unit Type and Functionality

Models of one manufacturer, and even more so of various brands, differ in appearance and potential capabilities.

Suppose pressure switch, which ensures timely shutdown of equipment, can be connected in two ways: using a flexible hose or directly to the body. This does not change the principle of operation, only the appearance is different.

More serious differences relate to the type of pump - the main working part. The most common self-priming devices that easily tolerate light water pollution and the presence of air in the pipes.

The main disadvantage of units of this type is the limited height of the liquid from the source (from 6 to 9 m). Another small drawback is the high noise level, but it is solved by installing the pump in a separate room.

Some models are equipped with an ejector, built-in or external. The built-in allows you to increase the depth of the water supply up to 15 m, while the external one is able to extract liquid from a depth of 45-50 m. The disadvantage is reduced efficiency and noise.

The ejector provides recirculated (looped) movement of water thanks to a special design - an additional sleeve immersed in water with a special nozzle

For wells and boreholes with a depth of up to 10 m, quieter multi-stage devices are used. They are more expensive and more complicated in construction, have a powerful head and a high degree of productivity. The main external difference of units of this type is the elongated shape of the working chamber, which holds several wheels instead of one.

For suburban areas with a small house and a shallow well (6-7 m), vortex pumping stations are suitable. They are distinguished by high pressure (which allows them to be used to increase pressure in the system), quiet operation, efficiency, but low productivity

Equipment Manufacturer Reputation

Choosing this or that model, you are sure to pay attention to the manufacturer and try to remember how reliable its products are. This is the right approach, because the lines of work of a pumping station are measured over the years, and there is no point in buying a poor-quality one.

Now almost all companies engaged in the production of pumping equipment are focused on consumer interest and have in their arsenal a whole set of models that differ in technical characteristics.

Famous domestic brands Gileks, Bison, Whirlwind compete with Italians Marina, Ergus, Pedrollo in the number of presented lines.

However, the palm belongs to the German brands Gardena, Metabo, Wilo SE, Kärcher, Grundfos, which have always been distinguished by excellent quality and maximum functionality.

All brands rooted in Russia have adapted their technology to local climatic conditions. Consider the rating of popular models, so that the idea of ​​pumping devices becomes more complete.

As you can see, in different models the difference in performance, lift height and power can be significant.
