CLDP (Closed Loop Differential Pump) is a hydraulic linear axis suitable for all applications with high density and high dynamics. Consisting of a servo motor, internal gear pump and a directly linked hydraulic cylinder, CLDP is a compact and closed system.

The integrated servo pump is matched to the surface area ratio of the cylinder. Speed and direction of movement is controlled without any directional or proportional valves. Because of the closed loop system, CLDP does not need a tank or external power pack. The necessary volume compensator is integrated.

Position control and pressure/force control is possible. The pressure transducer is integrated into the system (option). An integrated position feedback sensor is avaialable. Key features of CLDP are very high energy efficiency and virtually wearless operation. Hydraulic’s intrinsically good overload protection is combined with long life time.
