Currently, manufacturers produce only two main types of pumps: vibratory and centrifugal. Models of the second group do not pump liquids so smoothly, but they usually have higher performance and lower cost. The domestic market today offers a huge number of brands of such equipment.

Types of centrifugal pumps

Equipment of this type is most often one of the elements of water and sewer systems. According to the installation method, domestic centrifugal pumps are classified into:

1. Surface. This is the cheapest and at the same time easy to install and maintain type. The only disadvantage of such models is that they can only be used to pump water from wells or very shallow wells (8-10 m).
2. Semi-submersible. Pumps of this type have a specially shaped casing. They are most often used for installation in wells, very wide wells or dugouts (directly on the water). The engine of such models is located on the surface, while the suction system is located underwater.

3. Submersible. Since water is obtained from narrow deep wells in most areas today, such centrifugal domestic water pumps are the most popular among consumers. The body of models of this type is a narrow cylinder. They (together with the electrical cable) are immersed into the well on a nylon or metal cable.

Fecal and drainage centrifugal pumps can be both surface and submersible. They differ from water ones only in the presence of special additions: filters, particulate grinders, etc.

Most Popular Brands

Most of the models available on the market today are of fairly good quality. However, most often, owners of suburban areas buy a centrifugal electric household brand pump:

• Grundfos.
• Water cannon.
• Pedrollo.
• NGXM.
• Gardener.

Grundfos models

Household centrifugal pumps of this brand are produced by the Danish company of the same name, founded in 1945. The range of models produced by this company is unusually wide. There are both Grundfos industrial equipment on the market and those designed for installation in domestic systems. Borehole pumps of this brand are represented by two lines: SP and SQ. The second variety is designed for use in mines with very clean water. Four-inch SP models, as can be understood from the reviews, are capable of pumping water contaminated with sand or other impurities. In the manufacture of both options, the manufacturer uses stainless steel parts.

This company also produces fecal pumps of the SEG and APG series, as well as UPS models designed for heating systems.

Water Cannon Pumps

This brand is popular among domestic consumers not only for its excellent quality, but also for its low cost. The Russian company Dzhileks produces pumps "Vodomet". If desired, you can choose a model of this brand for both a well and a well with a diameter of 10 cm or more. The advantage of the Vodomet pumps is that they can be used to pump water heavily polluted with sand. Household centrifugal submersible water pumps of this brand, according to reviews, have one small drawback - they are not equipped with a check valve.

Pedrollo Models

Pumps of this brand have recently been gaining more and more popularity among domestic summer residents. They are produced by the Italian company of the same name. Their advantages include, first of all, a long service life and high efficiency. Also, their advantages are considered to be minimal hydraulic losses during pumping, quiet operation and ease of use.

Exist as industrialmodels of this brand, and designed for domestic needs. With their help, as evidenced by the reviews, it is possible to pump not only water, but also chemically aggressive environments. Very often, Pedrollo models are used for use in difficult operating conditions. Popular with consumers are not only centrifugal household water pumps from this manufacturer, but also fecal pumps.

Caliber pumps

These models are made in China and have very good performance. All household centrifugal pumps "Caliber" have been certified in the domestic ROSTEST center. Judging by consumer reviews, despite the fact that they are going to China, the quality is very good.

Caliber pumps are distinguished by high performance and long service life. Downhole centrifugal models of this brand are represented on the market by the NPCS line. For installation in wells, a household centrifugal pump NBC "Caliber" is usually used. Also, if you wish, you can buy fecal models of this brand or drainage.

NGXM

NGXM - monoblock centrifugal pumps equipped with a special built-in injector. Cases of models of this brand are made of stainless steel, and impellers are made of brass. NGXM surface pumps are designed for installation in wells and small wells, as they are able to lift water from a depth of no more than 9.5 meters.

Gardener models

Small well pumps are the most popularthis brand. They cost literally a penny, but you can use them for a very long time. Since the size of the household centrifugal submersible pump "Gardener" is small, it is often used to pump new wells before installing a permanent model that is sensitive to pollution. According to reviews, these babies are also suitable as equipment for cleaning hydraulic tanks from stagnant water. Sometimes Sadovod pumps are also installed in very shallow wells.

How to choose a centrifugal pump

When buying equipment of this type, in addition to the brand, you should, of course, pay attention to its other important characteristics. These include:

1. Performance. This is the volume of water pumped by the pump per unit of time. This parameter is calculated according to certain formulas. For a small house with 4-5 people, a 30-50 l/min model is usually sufficient. If there is a need for watering the garden or any animals are bred on the site, it is worth buying a pump with a higher capacity.
2. Head. From this indicator depends on what height the pump can raise water. The pressure is calculated quite simply. The height of the house itself is added to the depth of the mine, plus the coefficient of possible losses (10%).

Thus, modern household centrifugal pumps are productive, high-quality and reliable equipment. FROMusing them, you can easily provide water supply to a country house, water the garden, pump out the contents of cesspools. The equipment considered in the article is currently considered the best in Russia. However, of course, there are other brands of good centrifugal pumps on the market. When choosing this equipment, in addition to its parameters, one should pay attention to the reputation of the manufacturer. And then the purchased pump will serve faithfully for many years, doing its job perfectly.
