Features and detailed specifications of Rexroth piston pump A10VO

Thread Content

Description of Rexroth A10VO series piston pumps:
Specifications range from 10 to 140. Axial piston with swashplate design; open circuit. Series 31 (specifications from 18 to 140), Series 52 (specification 10). A wide range of controllers and actuators available (as listed below). Parallel shaft design for the same specifications, allowing the creation of combined pumps (excluding specification 10). Rexroth A10VSO variable piston pump, Series 31R: open circuit, RC 92 711/09.00. Specifications range from 28 to 140. Series 31R: rated pressure of 280 bar, peak pressure of 350 bar. Features of Rexroth A10VSO models in Series 31 and 52: – Variable axial piston pump with swashplate design for hydraulic open circuits; flow rate is proportional to drive speed and displacement, with stepless variation possible by adjusting the swashplate angle. – ISO-standard mounting flanges; flange connections comply with SAE metric standards. – Two housing oil drainage ports. – Excellent suction performance. – Capable of continuous operation at a pressure of up to 280 bar. – Low noise level. – Long service life. – Drive shaft can withstand axial and radial loads. – High power-to-weight ratio. – Wide range of control options. – Short control response time. – Parallel shaft design allows use in multi-circuit systems. Detailed guide to selecting Rexroth A10VSO models in Series 31 and 52: Example model: A10VSO18DFR1/31R-PPA12N00. A10VS – Swashplate-type variable pump, designed for industrial use; nominal pressure of 28 MPa, 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: clockwise, L: counterclockwise) P → Sealing (P: NBR with FKM shaft seal (nitrile rubber, in compliance with DIN ISO 1629); V: FKM (vulcanized rubber, in compliance with DIN ISO 1629)) P → Shaft end (P: solid shaft with key per DIN 6885; S: splined shaft per SAE; R: splined shaft per SAE (for higher drive torque)) ； 　　A → Mounting flange hole (A refers to ISO 2 hole, B refers to ISO 4 hole) ； 　　12 → Working oil port connection; {Pressure oil port B and suction port S} are in opposite directions; SAE oil port with metric set screw ； 　　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
