SELF-PRIMING REGENERATIVE PUMPS

A self-priming pump is a specialized liquid pump designed to initiate the pumping process by ensuring that the necessary liquid is present in the pump body or cavity. This feature is particularly advantageous for pumps used intermittently, offering potential improvements in operational efficiency. Self-priming centrifugal pumps are capable of handling liquids with entrained gas and can expel air from the suction line.

The operational principle involves fluid recirculation within the pump head, creating a vacuum that enables self-priming. These pumps excel at drawing water without requiring an external water source to start. They find applications in various settings, including pumping water from wells, addressing flooded basements, filling pools, and serving industrial needs for pumping water, chemicals, or sewage.
