"Self-priming pumps are a specific type of liquid pump designed to have the required liquid inside the cavity or pump body necessary to start the pumping process. This offers the potential for increased operating efficiencies in process plants where pumps are used for a variety of repeated yet intermittent operations.

A "self-priming" centrifugal pump overcomes the problem of air binding by mixing air with water to create a fluid with pumping properties much like those of regular water. The pump then gets rid of the air and moves water only, just like a standard centrifugal pump.

It is important to understand that self-priming pumps cannot operate without water in the casing. Here's how it works: During the priming cycle, air enters the pump and mixes with water at the impeller.

o accomplish this, a charge of liquid sufficient to prime the pump must be retained in the casing or in an accessory priming chamber." For more queries, checkout Tftpumps.com.
