Hydraulic Motor must have an SAE Standard (SAE J744C) mounting flange and
shaft size B , with 30 degree involute spline, 13T, 16/32 pitch.
Hydraulic Motor must produce the Torque required to drive the centrifugal pump
at the desired operating speed. For centrifugal pump GPM and TDH, read the
required RPM and BHP from pump performance curve, and calculate required torque
in Lbs-Ft, as follows:
Torque =
Hydraulic Motor selected must match with the flow and pressure capability of the hydraulic
power source system. The operating speed of the centrifugal pump will be controlled by the
valves in the hydraulic power source system.
