In normal conditions, common centrifugal pumps[1] are unable to evacuate the air from an inlet line leading to a fluid level whose geodetic altitude is below that of the pump. Self-priming pumps have to be capable of evacuating air (see Venting[2]) from the pump suction line without any external auxiliary devices.
Centrifugal pumps with an internal suction stage such as water jet pumps[3] or side channel pumps[4] are also classified as self-priming pumps.
Centrifugal pumps which are not designed with an internal or external self-priming stage can only start to pump the fluid after the pump has initially been primed with the fluid. In addition, a suction-side swing check valve or a vent valve must be fitted to prevent any siphon action and ensure that the fluid remains in the casing when the pump has been stopped. In self-priming centrifugal pumps with a separation c...
