Self Priming Pumps

Self Priming Pumps

Self-priming pumps are centrifugal pumps designed to re-establish their own prime, making them ideal for applications where the suction line may contain air or the pump must lift liquid from a lower level. By mixing a small amount of air with liquid already in the pump casing, the impeller creates suction that draws in more fluid, allowing continuous operation without manual priming.

 

These pumps are versatile and widely used across industries. Common applications include transferring clean, dirty, or muddy water, chemical handling (with compatible materials), irrigation, drainage, and boosting water pressure. They are also suitable for loading and unloading liquids in agricultural or industrial settings.

 

It’s important to note that self-priming pumps require some fluid in the casing to function correctly. Running dry can damage seals or impellers, so always ensure the pump is properly primed before use.
