Gorman-Rupp Roto-Prime Self Priming Centrifugal Pump with Air Release

For applications pumping over 23' vertically.

These units include an air release valve that evacuates air in the suction line to ensure positive self-priming when pumping against moderate to high static heads.

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.  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.
