Gorman Rupp Self-Priming Pumps

Gorman-Rupp self-priming pumps are the world’s leading choice for waste-handling applications in numerous industries. These centrifugal pumps are easy to install and easy to service.

They can be mounted high and dry at floor level with only the suction line in the liquid, thus eliminating the need for service personnel to enter the sump. The pumps can be serviced easily with common hand tools, thus reducing maintenance costs and time.

PRINCIPLE OF OPERATION

Self-Priming Centrifugal

Gorman-Rupp self-priming centrifugal pumps have two phases of operation: the priming and the pumping mode. In the priming stage, the pump acts like a liquid ring pump where a rotating impeller generates a vacuum at the impeller’s eye, which draws air into the pump from the suction line. At the same time, it creates a cylindrical ring of liquid inside the pump casing. This forms a gas-tight seal. Air bubbles are then trapped in the liquid within the impeller’s vanes and transported to the discharge port. There, the air is expelled and the liquid returns under gravity to the reservoir of the pump casing.

Liquid rises up gradually to the suction line as it is evacuated. This process continues until liquid replaces air in the suction piping and the pump. Here, the normal centrifugal pump operation starts.
