Self priming pumps

The self-priming pumps include, among others, the water suction pumps, the side-channel pumps and the centrifugal pumps with an internal suction stage as well. The self-priming pumps, in contrast to normal centrifugal pumps, must be able to vent the suction pipe of the pump without any other external auxiliary devices.
