A22VG
Xeriwell or Others
Rexroth A22VG is a variable double pump available with two axial piston rotary groups of swashplate design for hydrostatic drives in a closed circuit.
Features:
1) Variable double pump with two axial piston rotary groups of swashplate design for hydrostatic drives in a closed circuit.
2) The flow is proportional to the drive speed and displacement.
3) The flow can be infinitely varied by adjusting the swashplate angle.
4) Flow direction changes smoothly when the swashplate is moved through the neutral position.
5) Only one shared port for case drain fluid for both circuits.
6) Compact design for tight installation conditions.
