Gorman-Rupp Roto-Prime Self Priming Centrifugal Pumps

Description

Roto-Prime® self-priming centrifugal pumps are specifically designed for pumping petroleum products, petrochemicals and solvents. They are available as straight centrifugals or with the exclusive Roto-Prime® design. The Roto-Prime® design incorporates a variable capacity vane pump which quickly and automatically evacuates air and vapor, making them ideal for off-loading transports and stripping hoses. Optional air release evacuates air in the suction line to ensure positive self-priming even when pumping against moderate to high static heads.  Roto-Prime® pumps are actually two pumps in one: a variable capacity vane pump used during the priming cycle, and a standard centrifugal pump to move the liquid. If you are ordering a replacement pump, please provide the serial number off of your old pump so that the replacement pump is configured to the specifications of the old pump. If you are ordering a unit for the first time, please complete the Petroleum Pump Calculation Sheet to ensure the new pump is engineered to your specifications.
