Bosch Rexroth Variable Pumps

Bosch Rexroth Variable Pumps are world recognised for their energy saving and compact sizes. Rexroth Axial Piston Variable Pumps move with the trend toward into more compact machine tools, which are easily adapted and integrated into any automation architecture supporting multiple configurations and arrangements. Bosch Rexroth Axial Piston Pumps are extremely tough and highly reliable with a long service life lowering the maintenance costs for the user.

VARIABLE PUMPS

In axial piston variable pumps, the flow is proportional to the drive speed and the displacement. The flow can be steplessly changed by adjusting the swivel angle. Axial piston variable pumps are available for hydrostatic drives in open and closed circuits.
