Product Overview
The Rexroth A10VSO 45 DFR1/31R-PPA12N00 axial piston variable displacement pump is a high-performance, swashplate-type hydraulic pump engineered by Bosch Rexroth for demanding industrial and mobile applications. Part of the renowned A10VSO series, this pump features a nominal displacement of 45 cm³/rev and is configured with the DFR1 control variant, which combines pressure and flow control (load sensing) for precise, energy-efficient operation. The pump operates on the axial piston principle with a bent-axis-free swashplate design, delivering high pressure capability, excellent suction performance, and long service life. With its through-drive capability and SAE mounting flange, the A10VSO 45 is a direct-fit replacement for OEM installations and is widely used in plastic injection molding machines, metallurgical equipment, and industrial hydraulic power units.
