Water pumps. Short explained.

This is how water pumps work

KSB offers you different water pumps with different functions. Generally speaking, they are divided into three types: Self-priming pumps, centrifugal pumps and submersible borehole pumps.

Self-priming pumps
A self-priming water pump has got a pump casing designed with a suction nozzle and a discharge nozzle. The suction pipe at the suction nozzle serves to prime the pump with water. Impellers in the pump casing contribute to the suction and discharge forces and enable water to be drawn into the pump from a depth as low as eight metres. Among the pumps that are generally considered as self-priming are garden pumps, domestic water supply systems and rainwater pumps.

Centrifugal pumps
The priming effect of a centrifugal pump is less pronounced than that of a self-priming pump. This is why it always has to be supported during start-up. Centrifugal pumps are therefore suitable for applications with a low suction lift. The pump is primed with water prior to being started up.

Submersible borehole pumps
A submersible borehole pump is completely submerged in water. Like other submersible pumps, centrifugal pumps also have a vertically arranged shaft. The water can be transported via a connected discharge pipe. They are very frequently used in buried rainwater storage tanks. Grey water pumps are also part of the submersible borehole pump category and work to the same principle.
