A Series General Purpose Pumps
General Purpose Pumps for Pressure Lubrication, Hydraulic Service, Fuel Supply and General Transfer
Up to 59 GPM ● Up to 300 PSI
Roper A Series pumps are adaptable to a wide range of applications pumping clean fluids, such as pressure lubrication, hydraulic service, fuel supply or general liquid transfer.
These pumps are designed to operate at standard motor speeds, with provisions for flange or foot mounting. The internal bearings are lubricated by the fluid being pumped. With only two moving parts, the pumps run quietly.
They are manufactured and assembled with close tolerances, and regularly tested to insure dependable performance. Factory assembled for clockwise rotation (facing the pump drive shaft end), most may be reassembled for operation with equal effi ciency in a counter-clockwise rotation.
