What criteria should be followed when choosing a surface pump

A powerful surface pump is often used for an autonomous water supply device at a summer cottage. Self-priming unit raises water from a depth of up to 8 meters and has good performance. The name “surface” came from the location of the pump relative to the source. This equipment is installed on the ground, unlike submersible models.

Basic criteria for the selection of surface pumps

Surface pumps must be chosen carefully. First of all, the units are evaluated according to the principle of operation:

• Whirlwind. Designed for lifting water from a depth of 3 meters. They have not very high performance, therefore they are often used as an additional component for pumping liquid in the system.
• Centrifugal. More powerful pumps that can raise water from a depth of 8-10 meters and at the same time create a good pressure in the system.

In conjunction with a hydraulic accumulator and a pressure switch, a good centrifugal unit forms a pumping station for a family of 4 or more people.

Otherwise, choosing a surface pump for a suburban area, you need to pay attention to its parameters such as:

• Performance. As a rule, the nominal values ​​for the pump are indicated in its technical passport. The homeowner must calculate the required amount of water for the family or watering per hour. To do this, you need to use approximate norms (for watering - 1m3 / hour; for water supply at home - 0.58 m3 / hour x number of people in the family).
• Pump suction depth. For surface pumps, this indicator varies in the range of 7-10 meters. If the water mirror in the well is below this mark, you will have to take the submersible unit.
• The pressure. Consider depending on the distance between the installed pump and the source.
• Components for equipment. It is desirable that the device already has a check valve, fittings, hoses and a filter. This will seriously reduce the cost of running the pump further.
• Mains voltage on the site. If it is weak, it is better to choose a more powerful unit, or put a stabilizer under it.
• The material from which the equipment is made. For a good assembly, steel, brass and aluminum are used. Reliable vanes and bearings significantly extend the life of the pump.

It will be useful to pay attention to the noise of the pump in working condition, the presence of additional protection systems (from overheating), the ability to contact a service center in the region. If this does not happen in the area, certain difficulties may arise in servicing the unit.

Rating and review of the best models

According to the rating of the best surface pumps, the following models are popular:

• Pedrollo CKm 50. The pump is capable of pumping water from a 9-meter depth with a nominal head of 35 meters. In general, Italian Pedrollo pumps can work with both clean water and contaminated liquids (particles of sand, clay). The CKm 50 has moderate operating noise. The body of the pump is cast iron, the engine is aluminum, the rotor blades are brass.
• Belamos XA 13. An excellent model for supplying water from a depth of 8 meters. The unit capacity is 65 l / min. The mass of the pump is 11 kg. Power - 1200 W, head - 50 meters. The Belamos pump can safely work in an insulated caisson at -45 degrees outside. A cast iron housing and overheat protection ensure a long life of the equipment.
• Marina RSM 5-GA. The productivity of such a pump is 6m3 / h at a pressure of 60 meters. The permissible depth of water rise is 7-7.5 m. The unit power is 1.4 kW, but it fully justifies the performance of the pump. It works almost silently, all internal and external parts are coated with an anti-corrosion compound.
• Jumbo 70 / 50H.This pump is famous for the fact that it is able to increase starting speed not instantly, but gradually. As a result, a smooth start-up of the unit contributes to its longer operation. The pump pumps 4.2 m3 of water per hour from a maximum depth of 9 meters. Jumbo 70 / 50CH is especially popular among Russian summer residents due to its price and performance. The pump casing is made of cast iron with a special anti-corrosion top coating. The only minus of the Jumbo equipment is the noise in the work. But for using the unit in a garden plot, this is not a hindrance.
• Caliber NBC-900P. One of the most inexpensive pumps on the market. Its price on average is 4,000 rubles. The pump pumps about 3.3 m3 / hour. Furthermore, the permissible immersion depth of the intake pipe is 8 meters. Summer residents especially love this unit for a special stand frame on their legs - no need to worry about installing the equipment correctly. This is just a portable pump.
• Bison Master NS-M1-650-H. Swirl unit designed for clean water. Productivity is 40 l / min at a pressure of 45 meters. Low power device (650 W). Product weight - only 5 kg. With its dimensions and capabilities, it is ideal for watering a small garden.

Regardless of the popularity of the models, it is better to be guided by the specific parameters of the well / well and buy a pump according to your budget. A too expensive production model will not be entirely appropriate, for example, for watering a small area in the summer, just as a weak unit will not live up to expectations in providing the house with water all year round.

Reviews of the quietest surface pumps

Andrey, 36 years old: For a country house I set myself a VMtec VMEH 5/5-M pump. I shake water from a well. The lifting depth is 7.5 meters. The device is compact, does not take up much space, it stands in a caisson. It is quiet. Provides water to the cottage and sauna. In the summer for watering. For three years of operation did not fail, not clogged with garbage. Satisfied with the purchase.

Maxim, 39 years old: I bought myself an inexpensive VORTEX PN-1100N a year ago. Put in the country for a small house for 2 people and summer watering. Additionally installed a pressure switch to it and is now generally calm. The pump housing is durable made of stainless steel. The unit pumps water properly. During this period, the whole, did not rust. True, in the winter, I preserve the station somewhere from November to the end of March. Of the relative disadvantages - the lack of protection against idling. But I regularly monitor the mirror of water in the well. Everything seems to be in order. For its price, the pump is good.

Yuri, 43 years old: Jilex Jumbo 50/28 H-24. The pump was placed on a well with a lifting depth of 8 meters. It works properly and quietly. Stably maintains a pressure of 2.5 atm. True, when the voltage drops to 180, it shakes intermittently. I was saved by the stabilizer. Now the order. Jumbo serves a house for 4 people and a garden of 3 acres. For the money, the pump is quite decent.

Nikolay, 33 years old: Installed in the country Kraton PWP-01. I use to supply water from the well. Simple and low-powered brother. It pulls only 370 watts. But at the same time it is capable of pumping 200 liters of water in about 10 minutes. The case is made of cast iron, which makes us happy. It works quietly with a slight buzz. This is important because we have a small sleeping in a cradle in the summer. Of the minuses - the need to put a sand filter and buy an extension cord. Its not enough. Overall a good pump for seasonal use. I clean it for the winter, since I canned the summer cottage.
