Variable Displacement Pumps for Closed-Circuit Operation

All control systems used in the 02 series are based on a load-independent mechanism. Regardless of the selected control option, identical commands always result in the same machine response. Sensitive and precise machine control simplifies operation and enhances productivity. Various system options are available for mechanical, hydraulic, and electric solutions. Additional special regulatory functions, such as torque control and pressure cut-off, are also available. Reliable pump control can be easily integrated with any vehicle management system.
