Parker Gerotor Motors High-Torque Hydraulic Motor Solutions for Heavy-Duty Industrial Applications

Heavy Duty | High Torque | Low Speed

Parker Gerotor Motors are engineered to meet the demanding requirements of industrial applications that require high torque, low-speed operation, and exceptional reliability. Built on Parker’s proven gerotor technology, these hydraulic motors deliver outstanding performance, superior efficiency, and extended service life—even in the most challenging operating environments.

What is a Gerotor Motors?

A Gerotor Motor is a hydraulic motor that uses a precision-engineered inner rotor and outer stator (Gerotor gear set) to convert hydraulic pressure into rotary motion. As hydraulic oil flows through the motor, pressure differences generated inside the Gerotor assembly create rotational movement, delivering high torque at relatively low speeds. Their compact design, high efficiency, and long service life make them ideal for industrial hydraulic systems.

How Does a Geromotor Motor Work?

Why Choose Parker Gerotor Motors?
