A11VG
Xeriwell or Others
The A11VG is a variable displacement pump in axial piston swashplate design for hydrostatic transmissions in a closed circuit.
Primarily designed for use in mobile industrial applications.
The flow rate is proportional to the drive speed and the delivery volume and is infinitely variable.
It increases from 0 to its maximum value with increasing deflection. If the swash plate is adjusted through the zero position, the flow rate changes its direction of flow without jerking.
An easily adaptable program of control and regulating devices is available for the various adjustment and regulating functions.
The pump is equipped with two pressure relief valves for the respective high-pressure side, to protect the pump.
The valves are also feed valves to protect the hydromatic transmission (pump and motor) from overload. An integrated auxiliary pump serves as a feed and control pump and the maximum feed pressure is protected by the built-in feed pressure relief valve.
Type: A11VG12, A11VG19, A11VG35, A11VG50
