A4VG28EP2D1/32R-NSC10F003SHR902056258

Axial piston pump Bosch Rexroth series A4VG, type code A4VG28EP2D1/32R-NSC10F003SH, material number R902056258. Nominal size: NG 28. Axial piston unit: swashplate design, variable, nominal pressure 400 bar, maximum pressure 450 bar (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 for single pump ANSI B92.1a (S). Mounting flange: SAE J744 2-hole (C). Working port (port plate): SAE working port A and B, same side right suction port S bottom (10). Boost pump: integrated boost pump with and without through drive (F). 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). Filtration boost circuit/external boost pressure supply: filtration in the boost pump suction line (S).
