About this item

  • High Pressure Hydraulic Pump or Motor, Bi-directional rotation. Universal SAE A mounting flange and shaft sizes fit readily available pump/motor bell housing adapters and couplings. Many motors of this type are in appllications that this could be used to replace.
  • IMPORTANT: THE LOW PRESSURE SIDE OF THE MOTOR MUST NOT EXCEED 100 PSI OR THE SHAFT SEAL WILL LEAK. IF THE OUTLET PRESSURE EXCEEDS 100 PSI CONNECT THE EXTERNAL DRAIN PORT LOCATED ON THE REAR COVER TO YOUR TANK. MAKE SURE THERE ARE MINIMAL RESTRICTICTIONS TO THE TANK.


Operational as a fixed displacement gear pump or motor. The shaft can also be rotated clockwise or counterclockwise. Proven high quality robust design successfully designed into many high volume applications. 72.5 psi maximum low-pressure side (outlet). Exceeding this could create excessive pressure in the housing and leakage from the shaft seal. Make sure there are minimal restrictions when connecting to the reservoir. This motor comes with a built-in shuttle check valve that automatically sends leakage oil to low pressure side. No need for a separate drain line. Cost effect method as a pump or motor for high power rotational motion to drive fans, conveyors, power equipment in construction, agricultural, industrial, and commercial applications. Use with speed reducing gear boxes for winches, wheel drives or any other slower rotational motion needed.
