Rexroth A7V Variable Displacement pump |
series 2.0, and 5.1, axial piston unit, bent axis design
size 20 to 500, high pressure range up to 40MPa (400 bar)
|
Variable displacement pump, axial piston bent axis design, for hydrostatic transmissions in open circuits.
The flow is proportional to the drive speed and the displacement and is steplessly variable at constant drive speed.
Comprehensive program of control devices for every control and regulating function.
Simplified high performance rotary group with enhanced technical data and well-proven spherical control area.
|
Robust roller bearings for high loads.
Hydrostatic unloading of bearings possible for continuous.
pressures up to 400 bar.
Operation on both mineral and fire-resistant fluids.
Improved port plate design and compact construction reduces noise level by 5 dBA
