Stock Rexroth High Efficiency A10VO71 DFLR Series Variable Hydraulic Piston Pump 280 Bar Engineering Equipment A10VO180 A10VO140
The Rexroth 32 series A10VO140 is a variable displacement axial piston pump designed for open circuit applications. This swashplate design pump features a through drive capability, allowing multiple pump arrangements. Key specifications include a nominal displacement of 140 cm³/rev and a maximum operating pressure of 350 bar, with a peak of 400 bar. The A10VO140 is engineered for mobile and industrial hydraulics, offering high power density and efficiency. Its variable displacement is controlled via a pressure compensator (LR), a load-sensing controller (LRDS), or a constant power regulator (LROB), enabling precise flow adjustment to match system demand, reducing energy consumption and heat generation. The pump is known for its robust construction, reliable performance, and long service life, making it suitable for demanding applications in construction machinery, material handling, and industrial presses.

FAQ
Q:What control options are available?
A:Common controls: DR (constant pressure), DFR/DFR1 (load‑sensing), DRS (load‑sensing + power limitation), ER
(electro‑proportional), DRG (remote pressure control).
Q:Can the control method be customized?
A:Yes, we can customize controls (DR/DFR/DFR1/ER, etc.) per model. Please provide full model code (e.g., A10VSO18DFR1/31R).
Q:Which devices is it compatible with?
A:Excavators, loaders, cranes, injection molding machines, machine tools, presses, sanitation trucks, agricultural machinery, etc.,for open‑circuit systems.
Q:Can it be used as a replacement for pumps from other brands?
A:Can replace Rexroth same series, some Parker/PV, Hawe, etc. Need to verify displacement, pressure, control, and mounting dimensions.
Q:How is after-sales service handled?
A:Technical support provided; free replacement/repair for non‑human defects within warranty; spare parts and repair service available.
