Side channel pump

The side channel pump is a special design of a centrifugal pump, which is often regarded as a mixture of centrifugal and positive displacement pump.

They transport the fluid through a star-shaped wheel into a channel next to the impeller. The delivery heads achieved are 5 to 15 times higher than those of radial impellers.

The pumps are self-priming. They are used in particular for the conveyance of liquid-gas mixtures (partial gas conveyance) and for special suction requirements.

The efficiency is comparatively low. Therefore, the power range is only up to about 4 kW.

Due to the narrow gaps, they are generally not suitable for conveying fluids with abrasive components.
