Rexroth A10VO, parameters and features of the Rexroth piston pump A10VO

Thread Content

Description of Rexroth A10VO series piston pumps: Specifications range from 10 to 140; axial piston design with swashplate mechanism, open circuit. Series 31 (specifications 18 to 140) and Series 52 (specification 10). A wide range of controllers and actuators available (as listed below). Pumps with the same specifications and a common shaft design can be combined to form multi-pump systems (except for specification 10). Rexroth A10VSO variable piston pump. Series 31R, open circuit, RC 92 711/09.00; specifications from 28...140. Rated pressure for Series 31R: 280 bar; peak pressure: 350 bar. Features of Rexroth A10VSO models in Series 31 and 52: – Axial piston variable pumps with swashplate mechanism for hydraulic open circuits – Flow rate is proportional to drive speed and displacement; stepless variation can be achieved by adjusting the swashplate angle – ISO-standard mounting flanges – Flange connections comply with SAE metric standards – Two housing oil drain holes – Excellent suction performance – Allows continuous operation at pressures up to 280 bar – Low noise – Long service life – Drive shaft can withstand axial and radial loads – High power-to-weight ratio – A wide range of control options – Fast control response time – Common shaft design enables use in multi-circuit systems. Detailed guide to selecting Rexroth A10VSO models in Series 31 and 52 in Germany: Example models: A10VSO18DFR1/31R-PPA12N00. A10VS – Swashplate-type variable pump; used for industrial applications, with a nominal pressure of 28 MPa and a maximum pressure of 35 MPa； O → Operation mode; this series is used for open-loop systems ； 18 → Displacement specification: This model has a displacement of 18 m3 (other common displacement specifications include 10, 28, 45, 71, 100, 140, etc.). DFR1 → Control mechanism; (DG denotes two-digit control with direct drive) ； DR(G) Table ； Indicating pressure control remote control ； DFR (1) Pressure/Flow Control ； No small hole in the X oil circuit with 1 finger present ； DFLR pressure/flow/power control ； FHD flow control, related to pilot pressure with pressure control ； FE1** Flow rate electronic control ； DFE1** Pressure/flow electronic control ； ED electro-hydraulic pressure control) ； 31 → Product series R → Rotation direction (R for clockwise, L for counterclockwise) P → Sealing (P refers to NBR (nitrile rubber, in compliance with DIN ISO 1629) with FKM shaft seals; V refers to FKM (fluorocarbon rubber, in compliance with DIN ISO 1629)) P → Shaft end (P refers to straight shaft with keys per DIN 6885; S refers to splined shaft per SAE; R refers to splined shaft per SAE (for higher driving torque)) ； A → Mounting flange hole (A refers to ISO 2 hole, B refers to ISO 4 hole) ； 12 → Connection for working oil port; {Pressure oil port B and suction port S} are in opposite directions; SAE oil port with metric set screws ； N00 → Spindle drive; (N00 has no spindle drive) ； There are shaft-driven types with axial pumps, gear pumps, as well as radial piston pumps such as KB2, K51, KB3, K01, and so on
