Rexroth A4VSO40DR A4VSO71DR A4VSO125DR A4VSO180DR A4VSO180DR/3OR-PPB13N00 A4VSO series hydraulic pump.

For the description and operation of the various controls, see relevant RA-sheets (see page 2) – Swashplate design – Infinitely variable displacement – Good self priming suction characteristics – Continuous operating pressure of 5100 psi (350 bar) – Low noise level – Excellent service life – Drive shaft able to accept axial and radial loading – Low power to weight ratio – Compact modular design – Short control times – Over-center design (swallow circuits) – Through drive and pump combinations possible – Swivel angle indicator standard – Installation positional optional – Operation on HF fluids permitted at derated parameters Axial piston variable displacement pump A4VSO is of swashplate design and is designed for open circuit operation. Flow is proportional to input speed and displacement, and is infinitely variable by adjustment of the swashplate angle
