How does a water pump operate?

There are many different types of water pumps, including submersible pumps, irrigation pumps and circulation pumps. Although all pumps operate differently, generally speaking, pumps can be divided into three main categories. There are the self-priming pumps, centrifugal pumps and underwater pumps.

Self-priming pumps are placed outside of the water. The pump’s engine operates the pump housing. The pump housing of a self-priming pump is equipped with a suction and delivery diameter. Using the suction diameter, the pump is able to suck water by means of a suction hose. The end of the suction hose can be positioned in the source (under water). The pump’s housing includes one or multiple impellers. Impellers resemble closed rotor blades that exert a certain suction and compressive force by spinning around. Rotation of the impellers releases these forces and allows the pump to suck up water at a maximum depth of 8 meters. The pressure force in these types of pumps is always much greater and is expressed in head rate, or maximum pressure. As a rule of thumb: the more impellers, the greater the pressure the pump can exert. Other pumps that fall into this category include irrigation pumps, booster pumps and rainwater harvesting pumps.

Centrifugal pumps are largely the same as self-priming pumps, although they either have very light self-priming features or none at all. Given that centrifugal pumps have less suction power, they must always be manually started. Therefore, these pumps are often used for smaller suction heights, or systems where the water is already fed to the pump or closed systems (circulation pumps).
