Variable displacement pump HPV-02

Variable displacement pump HPV-02

Variable displacement pumps for closed circuit operation

All the controls used in the Series 02 are based on a load-independent control mechanism. No matter which control is used: identical commands always result in the same response in the machine. The sensitive and precise machine control makes work easier and increases productivity. Various customer system options for mechanical, hydraulic and electric input solutions are available. Further special regulating features like torque control and pressure cut-off are also available. The reliable control of the pump can easily be integrated into any kind of vehicle management control system.
