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.


Quiet-Running Helical Gears:

  • Heat treated cast-iron pumping gears are accurately machined for quiet, efficient operation and long life.
  • The pumping gears are keyed to their shafts with a sliding fit and are easily replaced.
  • Accurate machining ensures proper meshing and reduces friction and vibration

Precision-Ground Shafts:

  • The steel shafts are induction hardened in the bearing and sealing areas and are precision ground to exacting standards for maximum life.
  • Hardened stainless steel shafts available.

Long-Lasting Bearing Surfaces:

  • Bearings are special wear-resistant, high-lead bronze. Iron and carbon bearings are available.
  • Four heavy duty sleeve bearings provide positive support to pumping gears and ensure long, efficient service.
  • Bearing grooves allow circulation of the liquid being pumped for lubrication & control of bearing temperature
  • Outboard drive shaft bearing supports external radial loads and absorbs axial thrust loads.

Rugged Housings:

  • Standard castings are cast iron.
  • Precise manufacturing tolerances provide minimum clearances for maximum pumping efficiency.
  • Large, hardened steel dowel pins ensure positive alignment between the faceplate, case, and backplate.
