Courtesy: Bosch RexrothRexroth's A15VSO hydraulic axial-piston pump is designed for stationary applications in open circuit operation and meets pressure requirements to 420 bars and recovers potential energy during pump/motor operation almost completely. Equipped with a universal through drive, the A15VSO is designed to simplify the process of combining different pumps.

The housing structure, optimized for minimum sound emissions, reduces noise and the airborne noise level has been reduced in average by up to two dB(A) at full flow operation and up to three dB(A) during pressure holding periods (high-pressure stand by). In addition, the development engineers shifted the operating noise to a frequency range that is perceived as sonorous and more agreeable to the human ear.

Further design improvements bring the overall efficiency of the axial-piston pump up to 93%. The swivel range, for example, has been expanded to +/- 100% to enable complete over center operation for extremely fast and efficient decompression.

The A15VSO is available in sizes 110, 145, 175, 210 and 280 cc at a nominal pressure of 350 bar and a maximum pressure of 420 bar. The standard 280cc pump can run at 1,800 rpm with flooded suction.

The housing, which features an optimized layout of flow channels, simplifies the process of fitting the pump even in very tight spaces. A boosted version with impeller (A15VLO) is also available for up to 20% higher operating speeds.
