Gear motors are used to convert the fluid pressure into mechanical energy. The PM23 engines are designed for advanced hydraulic systems with low throughput (up to about 8 kW) with high operational reliability and long service life. A wide variety of designs with different drives, connecting flanges, inlet and outlet fluid openings make it possible to produce motors that will be used both in stationary hydraulic systems and in mobile machines and equipment. The types of joints and flanges, as well as other connecting dimensions, correspond to all world standards.

The engines are made of high quality aluminum alloys with steel gears and they are equipped with a hydraulic compensation of a new generation of axial play providing stable performance and torque within the entire range of speeds and temperatures. As for their dimensions, PM23 motors are fully interchangeable with PM and PM2 motors.
