BOSCH Rexroth A2FO Fixed Displacement Pump

Features for A2FO10 pumpFixed displacement pump A2FO of axial piston, bent axis design suitable for hydrostatic drives in open circuits.Suitable for use in mobile or industrial applications.Output flow is proportional to drive speed and displacement.The drive shaft bearings design to give the service life expected in these areas of operation.Careful selection of the displacements offer, permit sizes to match to practically every application.Favourable power / weight ratioCompact and economical designOptimum efficiencyOne piece pistons with piston rings Sizes 22 and 28Nominal pressure 400 barMaximum pressure 450 barSizes 71 to 500Nominal pressure 350 barMaximum pressure 400 bar Hydraulic fluidsThe A4FO fixed pump is designed for operation with HLPmineral oil according to DIN 51524.Application instructions and requirements for hydraulicfluids should take from the following data sheetsbefore the start of project planning:90220: Hydraulic fluids based on mineral oils and relatedhydrocarbons90221: Environmentally acceptable hydraulic fluids90222: Fire-resistant, water-free hydraulic fluids(HFDR/HFDU)90223: Fire-resistant, water-containing hydraulic fluids(HFC, HFB, HFAE, HFAS)Sizes 22 and 28 are not suitable for operation with HFA,HFB and HFC. Details regarding the choice of hydraulic fluidThe hydraulic fluid should be selected such that the operating viscosity in the operating temperature range is withinthe optimum range (νopt, see selection diagram). NoteAt no point of the component may the temperature be higherthan 115 degree (sizes 22 and 28) and 90 degree (sizes 71 to 500).The temperature difference specified in the table is to be takeninto account when determining the viscosity in the bearing.If the above conditions cannot be maintained due toextreme operating parameters, please contact the responsible member of staff at Bosch Rexroth.Sizes 5…1000Series 6Nominal pressure up to 400 barPeak pressure up to 450 bar
