TOP 10 best centrifugal pumps: how to choose, reviews



[ad_1]

A centrifugal pump is a device that, by means of centrifugal force, forces a liquid to move in a specified direction. The device is used both in domestic conditions and in the extraction of useful resources, such as oil. It is used in houses, cottages, in industries located far from water supply systems. We figure out how to choose a centrifugal pump to provide automatic water supply in a house or in the country. The article presents a brief overview, prices, features, advantages and disadvantages of various models, as well as a rating of the best centrifugal pumps according to customer reviews.

How to choose a centrifugal pump?

The centrifugal pump for water is produced in several types:

  • A submersible well pump resembles an elongated cylinder and works when completely immersed in water. Thanks to the design features, the specialists managed to create a powerful device that cannot be compared with its predecessors.
  • For installation above the liquid level or surface — the most popular of the presented models. It is placed on the surface and pumps liquid with a hose. Such a device is easy to install, and if necessary, it can be transported to other facilities.
  • Semi-submersible — partially located in the aquatic environment. The motor is held on top by a float. In terms of power, they are lower than surface ones, so they are used extremely rarely.

The choice of pump is influenced by 2 criteria: pressure and water supply. Before buying a device, experts recommend:

  • pay attention to the noise level;
  • find out the ratio of the depth of the well and the depth at which the device can operate;
  • calculate the pressure and flow of water;
  • take into account the percentage of impurities and sand in the liquid.

When buying a unit, you need to pay attention to 3 price parameters: the price of the pump itself, the cost of operation and installation. Different segments have a distinctive service life, so if a consumer decides to buy a high-quality and durable device, it is worth considering products from the premium segment.
