Applications

Self-priming pump is a special type of centrifugal pump that has the ability to self-prime and operate normally without the need for liquid filling. Self-priming pumps are widely used in industrial drainage, water supply to high-rise buildings, garden irrigation, boosting fire protection systems, and circulating HVAC refrigeration.

Tips: How does a self-priming pump work?

A self-priming pump is a type of pump that is capable of drawing and moving fluid without the need for external priming. It is designed to eliminate the need for manual priming or the use of additional equipment to remove air or gases from the pumping system.

The functioning of a self-priming pump relies on a combination of centrifugal force and the presence of an air-water mixture within the pump casing. When the pump is initially started, it creates a spinning motion within the casing, generating centrifugal force. This force helps to separate the air and water within the pump.

As the impeller rotates, the centrifugal force pushes the water outward, while the air, being lighter, moves towards the center of the impeller. This separation of air and water creates a partial vacuum within the pump casing. The vacuum causes atmospheric pressure to force water into the suction pipe and ultimately into the pump.

Once the air is expelled and the pump is filled with water, the self-priming pump can operate like a standard centrifugal pump, continuously drawing water from the source and moving it through the system.
