10 HP Closed-Loop Hydraulic Power Unit — Up to 58 LPM

The HydoPax CP40 is a compact and robust closed-loop hydraulic power unit designed to deliver up to 58 LPM of bidirectional hydraulic flow with electronically controlled variable displacement.

Powered by a 10 HP / 7.5 kW three-phase electric motor and a Bosch Rexroth A4VG40 variable-displacement axial piston pump, the CP40 provides precise and efficient hydraulic power for applications requiring bidirectional flow, variable speed, and electronic control.

The A4VG40 features a 40 cc/rev maximum displacement and proportional electric control, allowing the pump displacement and flow direction to be continuously adjusted according to the control signal.

At a maximum motor speed of 1,450 RPM, the pump provides a theoretical maximum displacement flow of approximately 58 LPM. Actual delivered flow depends on pump efficiency, operating pressure, temperature, and system configuration.

The CP40 is designed for hydraulic drive, testing, simulation, mobile equipment, and custom industrial applications where precise bidirectional hydraulic control is required.
