Centrifugal pumps which have the ability to pump mixtures of water and air as well as to vent the suction line of air, are deemed to be self-priming pumps. With the addition of a check valve in the suction pipework, standard centrifugal pumps can be self-priming if the casing is filled with water upon startup. Thus, the suction pipework cannot drain water.

Centrifugal jet self priming pumps are used in applications such as shallow well, small farms, domestic, pressure boosting, gardens, fertigation and drinking water supply.
