Description

The KEDA K7VO axial piston variable pump features optimized rotary groups, which can improve the overall efficiency by 3 to 5 percent. The total efficiency of mobile working machines is increased, thus reducing the operator's fuel consumption and operating costs. Performing pressure determines its hydraulic efficiency. The higher the pressure, the lower the flow needed to transmit the same power, reducing the flow losses in the system. KEDA axial piston variable pump K7VO offers a pressure of 350 / 400 bar, a force much higher than comparable products typically used in concrete mixers and compact excavators.
