AA4VG40NVDM1/32W-NUC52N004E-SR902022387
Axial piston pump Bosch Rexroth series A4VG, type code AA4VG40NVDM1/32W-NUC52N004E-S, material number R902022387. Nominal size: NG 40. 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 ANSI B92.1a only for combination pump – 2nd pump (U). Mounting flange: SAE J744 2-hole (C). 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 direct operated, fixed setting 1450 to 3600 psi without bypass (100 to 250 bar) (4). 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).
