AA4VG40HWD1/32R-NSC52F093DR902112580
Axial piston pump Bosch Rexroth series A4VG, type code AA4VG40HWD1/32R-NSC52F093D, material number R902112580. 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). Control device: proportional control hydraulic mechanical servo (HW). Pressure cut-off: pressure cut-off (D). DA control valve: without DA control valve (1). Direction of rotation: viewed on drive shaft clockwise (R). 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-hole (C). Working port (port plate): SAE working port A and B, top and bottom suction port S bottom (52). Boost pump: integrated boost pump with and without through drive (F). High-pressure relief valve Setting range ∆pHD: high-pressure relief valve 3600 to 6100 psi without bypass direct operated, fixed setting (250 to 420 bar) (3). Filtration boost circuit/external boost pressure supply: filtration in the boost pump pressure line Ports for external boost circuit filtration (Fe and Fa) (D).
