AA4VG56EP4D1/32R-NTCXXFXX3DP-SR902111798
Axial piston pump Bosch Rexroth series A4VG, type code AA4VG56EP4D1/32R-NTCXXFXX3DP-S, material number R902111798. 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). Control device: proportional control electric with inlet filtration in P U = 24 V (EP4). 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: 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). Connector for solenoids: DEUTSCH connector without suppressor diode molded, 2-pin (P). Standard/special version: special version (-S).
