AA4VG125EP7X1/32R-NTFXXK691EP-SR902154631
Axial piston pump Bosch Rexroth series A4VG, type code AA4VG125EP7X1/32R-NTFXXK691EP-S, material number R902154631. Nominal size: NG 125. Axial piston unit: swashplate design, variable, nominal pressure 5800 psi (400 bar), maximum pressure 6500 psi (A4V). Operating mode: pump, closed circuit (G). 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+4-hole (F). Boost pump: without integrated boost pump with through drive (K). Through drive: flange SAE J744 Hub for splined shaft, 152-2/4 (D) 1 3/4 in 13T 8/16DP (69). High-pressure relief valve Setting range ∆pHD: high-pressure relief valve, pilot operated 1450 to 6100 psi with bypass (100 to 420 bar) (1). Filtration boost circuit/external boost pressure supply: external boost pressure supply (version without integrated boost pump – N00, K...) (E). Connector for solenoids: DEUTSCH connector without suppressor diode molded, 2-pin (P). Standard/special version: special version (-S).
