Description

The Bosch Rexroth A A10VSO 71 DR /31R-VPA42N00 is an A10VSO series 31 variable-displacement axial piston pump in swashplate design for open hydraulic circuits. Factory article R902482660 has 71 cm³/rev maximum displacement and a pressure controller.

This execution uses clockwise rotation viewed from the shaft end, an ISO keyed shaft, a two-hole metric ISO 3019-2 flange and FKM seals, without a through drive. The factory card records 106.5 l/min maximum flow at its catalogued 1500.0 rpm operating point. This point does not represent the maximum permissible speed across all inlet-pressure and displacement conditions. Pressure definitions, fluid requirements and installation limits apply as specified for the standard series 31 unit.
