Product Description
Rexroth A4VSO Series Heavy-Duty Axial Piston Variable Pumps
Product Overview: The Rexroth A4VSO series is the premier power source for global industrial hydraulic systems, engineered for sustained heavy-duty operation in open-circuit applications. This series covers large displacement specifications, including the A4VSO355 and A4VSO250. Featured models like the A4VSO355LR2/30R-PPB13N00 and AHA4VSO250LR2S/30R-PPB13K24-S1167 are equipped with advanced LR2 (Constant Power Control) regulators. Renowned for its robust swashplate design and superior suction characteristics, the A4VSO is widely utilized in heavy forging presses, steel mill equipment, large injection molding machines, power plants, and marine deck machinery, ensuring stable performance under extreme conditions up to 400 Bar.
Key Technical Advantages:
Heavy-Duty Industrial Engineering: Features reinforced bearings and a large-volume cylinder block, supporting continuous operation at 350-400 Bar (5800 PSI), with overhaul intervals significantly exceeding industry standards.
Precision LR2 Power Control: Automatically modulates displacement to match the rated power of the motor or engine, preventing overloads and maintaining constant power output during load fluctuations for optimized efficiency.
Superior Silence & Suction Performance: Hydrodynamically optimized valve plates drastically reduce operational noise, while the high self-priming capability supports elevated drive speeds.
Extended Service Life: Built for the Series 30 industrial line, the rotating groups utilize highly wear-resistant materials, compatible with various mineral oils and fire-resistant hydraulic fluids.
100% Standardized Compatibility: Manufactured to strict Rexroth factory specifications, ensuring mounting flanges (P spec) and splined shafts (B/K spec) align perfectly for a seamless “drop-in” replacement.
