A15VSO

New benchmark for ultra-low noise emissions: The A15VSO operates up to three dB(A) quieter than previously available high-pressure axial-piston pumps

Rexroth combines significantly lower noise emissions with further improved efficiency in the new A15VSO axial-piston unit for stationary applications in open circuit operation. It can meet pressure requirements to 420 bar and recovers potential energy during pump/motor operation almost completely. This enables innovative recuperation concepts that can improve the efficiency of machines and systems. Equipped with a universal through drive, the A15VSO seamlessly integrates into the Rexroth line of products and simplifies the process of combining different pumps.

Rexroth developers used state-of-the-art simulation tools in all design stages. The housing structure, optimized for minimum sound emissions, reduces noise considerably. Subsequently, the air borne noise level has been reduced in average by up to 2 dB(A) at full flow operation and up to 3 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 by the human ear.

Further design improvements increase the overall efficiency of the axial-piston pump to 93 percent. The swivel range, for example, has been increased to +/- 100 percent to enable complete over center operation and an extremely fast decrease of pressure. In the pump/motor operating mode an almost complete recuperation of potential energy is possible for instance during lowering of a load or braking of a moving mass. This opens up new opportunities for maximizing the energy efficiency of machines and systems, whereby the robust and stable swivel action ensures highly dynamic performance with reduced response times. The first pump size of the A15VSO has a displacement of 280 cubic centimeter at a nominal pressure of 350 bar and a maximum pressure of 420 bar.

The new compact housing, which features an optimized layout of flow channels and better use of installation space, simplifies the process of fitting the pump even in very tight spaces. The universal through drive increases flexibility for customized drive solutions and can easily be used to connect axial-piston, gear, and other hydraulic pumps out of the comprehensive line of Rexroth pumps. Numerous hydraulic and electric controllers (also for remote control operation) enable efficient, highly precise control of power, pressure and flow as well as load-sensing functions.
