What is a Self Priming Pump?
Self priming pumps are centrifugal pumps with the ability to clear air from the suction line by mixing it with liquid in the pump body. It is important to understand that self priming pumps cannot operate without water in the casing!
Typically there are two types of self priming centrifugal pumps:
1) Open impeller self priming pumps e.g. A series from CALPEDA, which are used for pumping liquids with soft solids
2) Closed impeller self priming pumps e.g. NGX & MXA from CALPEDA , which are used to extract clean water from underground tanks and shallow wells.
