Gorman-Rupp, Self Priming Centrifugal Pump, 4″ x 4″ NPT, 111 PSI-84B31-B

Heavy-Duty Self-Priming Centrifugal Pumps

Gorman-Rupp 80 Series® medium head, mild solids-handling, self-priming centrifugal pumps are designed for non-stop work loads.

The straight-in-suction design of these high efficiency pumps guarantees quick positive priming and allows them to operate at higher suction levels than most other self-priming centrifugal pumps.

The liquid being pumped enters directly into the eye of the impeller, and a suction check valve prevents in-line return flow when the pump is shut off. And, because they have few moving parts, 80 Series pumps are easy to maintain and service, saving money in the long run.

80 Series self-priming centrifugal pumps are available in a variety of configurations for all of your industrial, construction, mining, agricultural, municipal and petroleum fluid handling needs.
