AA4VG56ED8D1/32R-NTCXXKXX3EQ-SR902231036
Axial piston pump Bosch Rexroth series A4VG, type code AA4VG56ED8D1/32R-NTCXXKXX3EQ-S, material number R902231036. Nominal size: NG 56. 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). 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 ANSI B92.1a for combination pump – 1st pump (T). Mounting flange: SAE J744 2-hole (C). Boost pump: without integrated boost pump with through drive (K). 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: external boost pressure supply (version without integrated boost pump – N00, K...) (E). Connector for solenoids: DEUTSCH connector molded, 2-pin with suppressor diode (only for EZ and DA) (Q). Standard/special version: special version (-S).
