Bosch Rexroth A10VSO Series 31 axial piston variable pump. All-purpose medium-pressure pump. Size 18 … 100; nominal 280 bar, maximum 350 bar; open circuit. Supplied by Twin Hydraulics Engineering across Malaysia.
A10VSO Series 31 is the industrial version of the A10VO: the same swashplate variable-displacement design, but tuned for stationary applications with low noise, high efficiency and long service life. Displacements are 18 to 140 cm³, nominal pressure 280 bar and maximum 350 bar. It is the pump most often found in Malaysian presses, rubber and plastics machinery, machine tools, steel-mill auxiliaries and hydraulic power packs, and variants are available for HFC water-glycol and other fire-resistant fluids.
Control options cover DR pressure control, DRG remote pressure control, DFR/DFR1 pressure-flow control, DFLR pressure-flow-power control, FE and FHD stroke/displacement controls, and ED/DFE1 electrohydraulic proportional control for closed-loop systems. Through-drives for tandem pumps and a wide choice of ISO and SAE flanges are standard.
What we need to quote: displacement (A10VSO18…140), control type, rotation, shaft, flange, port type and fluid type (mineral oil or HFC). 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.
