Rexroth A10VO85DRS/53R-VSC12N00

Description:

Rexroth A10VO85DRS/53R-VSC12N00 Hydraulic Piston Pump

Variable pump with axial piston rotary group in swashplate design for hydrostatic drives in open circuit.

The flow can be infinitely varied by adjusting the swashplate angle.

Stable bearing for long service life

High permissible drive speed

Favorable power-to-weight ratio – compact dimensions

Low noise

Excellent suction characteristics

Electro-hydraulic pressure control

Power control

Electro-proportional swivel angle control

Short response times
