PARKER MOTORS

Gear Motors, fixed displacement, cast iron body

The Parker Hannifin PGM 30/31, 50/51 and 75/76 hydraulic motors are manufactured with hi-tensile grey iron. Parker motors offer a wide variety of drive shafts that are designed for high-torque applications and unique pressure balanced thrust plates contribute to optimized performance.

They can be assembled as single or multiple motors with flow divider, piggyback and winch configurations.

Being an authorised Parker Hannifin distributor, as well as all the motors listed below, P & R hydraulics can obtain other units, spare parts and accessories for all Parker hydraulic motors. Additionally, we can inspect, repair and test Parker units; modify existing units and custom build units according to your specification and the application to which it is being turned.

Parker Axial Piston Motors – fixed displacement, bent axis

The F1 is a fixed displacement bent axis, truck hydraulic motor that can tolerate low temperature and high temperature shocks, and high acceleration.

F11/12 is the high performance bent axis, fixed displacement heavy-duty motor series. These Parker motors can be used in numerous applications in both open and closed loop circuits. The 40° angle between shaft and cylinder barrel allows for a very compact, lightweight motor. The simple straightforward design with very few moving parts, make them very reliable motors.
