Bosch Rexroth A10VO Series 31 axial piston variable pump. All-purpose medium-pressure pump. Size 18 … 100; nominal 280 bar, maximum 350 bar; open circuit.
The A10VO Series 31 is the industrial-duty member of the A10VO family: a swashplate-design variable pump for open-circuit systems in presses, machine tools, plastics machinery, marine auxiliaries and power units. Compared with the mobile-oriented Series 5x it offers larger displacements (28 to 140 cm³) and a wider choice of pressure and flow controls, including DR pressure control, DFR and DFR1 pressure/flow control, DFLR pressure/flow/power control, DRG remote pressure control and ED/DFE electrohydraulic variants. Through-drive options allow tandem or auxiliary pumps to be mounted directly.
Typical replacement situations we see in Malaysia: a worn pump that has lost flow under load, a controller that no longer holds standby pressure, or an OEM machine whose original pump is obsolete and needs a cross-reference to the current Series 31 or 32 equivalent. We can help with all three.
What we need to quote: displacement (e.g. A10VO71), control type (DR, DFR, DFLR…), direction of rotation, shaft type (splined or keyed), mounting flange and port type, and any through-drive requirement. Send the full type code from the nameplate if you have it — that avoids guesswork and gets you a firm price and lead time faster.
