A2V
Xeriwell or Others
Rexroth A2V series pump is an axial piston unit of bent axis design with variable displacement, for hydrostatic drives in closed and semiclosed, and open circuits.
Maximum flow is proportional to the drive speed an displacement and is infinitely variable at constant drive speed.
Comprehensive control programme for every controland regulating function.
Features:
1) New, simplified high performance rotary group with enhanced technical data and well-proven spherical control area.
2) Heavy duty rolling bearings for intermittent high pressure operation.
3) For continuous duty at high pressures, hydrostatic bearings are available.
4) Operation on fire-resistant fluids is possible.
5) Improved port plate design and compact design reduces noise level by 5 dBA.
6) Complete primary units with all auxiliary devices for closed circuits.
Type: A2V250, A2V355, A2V500, A2V1000

| 1)The values shown are valid for an absolute pressure of 1 bar at the suction inlet S1and for mineral oils. When idling,excess speed of 50 rpm is permissible at n0max2or nhmax2. By increasing the inlet pressure (pabs>1 bar),speeds may be increased up to "max. permissible speed (speed limit)" (see diagram). 2)Calculated with a volumetric efficiency of 97 %. | ||||||||
