Self Priming Centrifugal Engine Driven Pumps

Self Priming Centrifugal Engine Driven Pumps

Centrifugal self-priming pumps have an interesting working chamber structure – in the form of a snail. The impellers are fixed in the center of the housing. There can be one wheel, then the pump is called a single-stage, or there can be several – a multi-stage design.
