AA4VG125NVDM1/32W-NSF52N001E-SR902023839

Axial piston pump Bosch Rexroth series A4VG, type code AA4VG125NVDM1/32W-NSF52N001E-S, material number R902023839. 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). Pressure cut-off: pressure cut-off (D). Mechanical stroke limiter: mechanical stroke limiter, externally adjustable (M). DA control valve: without DA control valve (1). 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, top and bottom suction port S bottom (52). Boost pump: without integrated boost pump without through drive (N). Through drive: without through drive, only for version N and F (00). 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: external boost pressure supply (version without integrated boost pump – N00, K...) (E). Standard/special version: special version (-S).
