AA4VG125HD3/32L-NSF63FXX1D-SR902125390
Axial piston pump Bosch Rexroth series A4VG, type code AA4VG125HD3/32L-NSF63FXX1D-S, material number R902125390. Nominal size: NG 125. Axial piston unit: swashplate design, variable, nominal pressure 5800 psi (400 bar), maximum pressure 6500 psi (A4V). Operating mode: pump, closed circuit (G). Control device: proportional control pilot-pressure related, with inlet filtration in P hydraulic (HD3). Direction of rotation: viewed on drive shaft counter-clockwise (L). Sealing material: NBR (nitrile rubber), shaft seal made of FKM (fluorocarbon rubber) (N). Drive shaft: splined shaft for single pump ANSI B92.1a (S). Mounting flange: SAE J744 2+4-hole (F). Working port (port plate): SAE working port A and B, same side right suction port S at top (63). Boost pump: integrated boost pump with and without through drive (F). High-pressure relief valve Setting range ∆pHD: high-pressure relief valve, pilot operated 1450 to 6100 psi with bypass (100 to 420 bar) (1). Filtration boost circuit/external boost pressure supply: filtration in the boost pump pressure line Ports for external boost circuit filtration (Fe and Fa) (D). Standard/special version: special version (-S).
