A4VG56EZ1DM1/32L-NSC02N003E-SR902022105

Axial piston pump Bosch Rexroth series A4VG, type code A4VG56EZ1DM1/32L-NSC02N003E-S, material number R902022105. Nominal size: NG 56. Axial piston unit: swashplate design, variable, nominal pressure 400 bar, maximum pressure 450 bar (A4V). Operating mode: pump, closed circuit (G). Control device: two-point control, U = 12 V electric with switching solenoid (EZ1). Pressure cut-off: pressure cut-off (D). Mechanical stroke limiter: mechanical stroke limiter, externally adjustable (M). DA control valve: without DA control valve (1). 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-hole (C). Working port (port plate): SAE working port A and B, top and bottom suction port S bottom (02). 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 250 … 420 bar without bypass direct operated, fixed setting (3).
