BOSCH Rexroth A10VNO Axial Variable Piston Pump
Features – Axial piston variable pump in swashplate design for hydrostatic drives in open circuits – Flow is proportional to drive speed and displacement. It can be infinitely varied by adjustment of the swashplate. – High power to weight ratio-small dimensions – Low noise level – Permissible continuous pressure 210 bar – Axial and radial loading of drive shaft possible – Pressure and flow control – Short response times – Well proven A10-technology – Extreme small mounting dimensions – Cost effective alternative to fixed displacement pumps – Costs -optimized design Series 52/53 Size A10VNO28 A10VNO45 A10VNO63 A10VNO85 Nominal pressure 210 bar Peak pressure 250 bar
