A10VSO45 Rexroth A10VSO Series 31 Axial Piston Pump

A10VSO45 Rexroth A10VSO series 31 axial piston pump A10VSO45 Features Variable pump with axial piston rotary group in swashplate design for hydrostatic drives in open circuit. Flow is proportional to drive speed and displacement. The flow can be smoothly changed by adjustingthe swashplate. 2 drain ports Excellent suction characteristics Low noise level Long service life Good power to weight ratio Versatile controller range Short control time The through drive is suitable for adding gear pumps and axial piston pumps up to the same size, i.e., 100% through drive. For size 140 please refer to data sheet 92705 All-purpose medium pressure pump Size 18 (A10VSO) Sizes 28 to 100 (A10VO) Nominal pressure 280 bar (4100 psi) Maximum pressure 350 bar (5100 psi) Open circuit Hydraulic fluids The A10V(S)O variable pump is designed for operation with HLP mineral oil according to DIN 51524. See the following data sheets for application instructions and requirements for hydraulic fluids before the start of project planning: ▶ 90220: Hydr aulic fluids based on mineral oils and related hydrocarbons ▶ 90221: Env ironmentally acceptable hydraulic fluids ▶ 90222: HFD hydr aulic fluids (for permissible technical data, see data sheet 90225) Selection of hydraulic fluid Bosch Rexroth evaluates hydraulic fluids on the basis of the Fluid Rating according to the technical data sheet 90235. Hydraulic fluids with positive evaluation in the Fluid Rating are provided in the following technical data sheet: ▶ 90245: Bosch Rexroth Fluid Rating List for Rexroth hydraulic components (pumps and motors) Selection of hydraulic fluid shall make sure that the operating viscosity in the operating temperature range is within the optimum range (νopt; see selection diagram).
