Hydraulic power unit is a hydraulic power assembly that generally includes a motor, hydraulic pump, hydraulic control element, filter, fluid reservoir and other hydraulic components.

They are used to drive cylinders, motors, actuators and other actuating parts through external pipeline system, and subsequently create starting, stopping, rotary motion, or commutation. Finally, the power unit provides the power needed by the terminal mechanisms.

With more than 30 years of experience in the hydraulic field, GRH’s hydraulic power units are widely used in automobile elevators, scissor-type lifting tables, dock levelers, snow removal trucks and more. Custom hydraulic power units are also available. The modular design allows us to quickly propose solutions and meet your needs through a combination of standard modules according to customer requirements. Premium key part configuration ensures a higher performance level and longer service life, while precise parts processing ensures a higher efficiency and strict process control ensures reliable product quality.
