Taking cognisance of the increasing emphasis and legislation on environmental noise reduction, Rexroth has designed the A10VSO axial piston pump with the reduction of noise formation in mind.
Rexroth’s A10VSO, Series 32 axial piston pump is quieter, more efficient and flexible than previous models
Hytec operations manager, Freddie Kuhn, explains that the causes of noise include structure-borne sound and air-borne sound. "By considering both causes, Rexroth has reduced airborne noise level in this pump series by 3 dB(A) and also realised a considerable reduction in structure-borne sound."
In many applications it may be necessary to install more than one pump depending on the system functions. If this is the case, it is easy to mount the additional pumps onto the through drive of the first pump without the need of an extra prime mover.
"The universal through drive enables cost savings with respect to storing several different versions of the primary pump and also offers a high level of flexibility when needing to adapt to changing requirements," Kuhn adds.
A pre-compression volume (PVC) can be integrated as an option to reduce pulsation by up to 50%. This reduces the fluid-borne noise level considerably, in particular where the power unit is installed some distance away from the machine.
