Hydraulic Power Unit (HPU

Our hydraulic power unit (HPU) is the heart of hydraulic systems, integrating key components such as AC/DC motors, hydraulic pumps (gear pump, vane pump, piston pump), oil tanks, control valves, filters, coolers and electrical control systems. It provides pressurized hydraulic oil to drive hydraulic cylinders, motors, valves and other actuators, realizing linear or rotary motion control of mechanical equipment. With a modular design, we support full customization of parameters including flow rate, working pressure, motor power, oil tank capacity, operating voltage and control mode, to meet the unique power needs of different hydraulic systems and application scenarios. Whether for standard industrial equipment or special engineering machinery, our hydraulic power units deliver reliable, efficient and stable power output, and are widely recognized in construction machinery, lifting platforms, sanitation vehicles, automotive maintenance, industrial automation and other industries.
