Product Description
Rexroth A20VO520 & A20VLO190 Series Double Variable Pumps
Product Overview: The Rexroth A20VO and A20VLO series represent the pinnacle of high-power-density double axial piston variable pumps for Open Circuit systems. By integrating two high-displacement units (up to 520cm³/rev for A20VO520), these pumps provide the essential power for ultra-large excavators and mining machinery. Featuring the optimized L-specification (Self-Priming) design, the A20VLO190 ensures superior suction performance at high rotational speeds. Integrated with advanced LR3GN power control, this series perfectly matches the engine’s power curve for optimized energy distribution.
Key Technical Advantages:
Massive Power Integration: Delivering a combined displacement of up to 520cc, the A20VO520 maximizes flow output within a compact double-pump installation footprint.
Superior Self-Priming (L Spec): In the A20VLO190 model, enhanced flow paths boost suction capability, allowing stable operation at higher speeds without a charge pump, simplifying system design.
Intelligent LR3GN/DRS Modulation: * LR3GN Models: Integrate constant power, pressure cut-off, and hydraulic adjustment to dynamically balance load and engine power, preventing stalls and reducing fuel consumption.
DRS Models: Provide precise Load Sensing (LS) modulation for on-demand oil delivery.
Heavy-Duty High-Pressure Durability: Rated at 350 Bar with peak cycles up to 400 Bar. Reinforced swashplate supports and specialized bearings ensure extended service life under extreme shock loads.
Robust Thru-Drive (K99): The K99 thru-drive capability allows for tandem mounting of auxiliary pumps, optimizing power distribution for multi-circuit hydraulic systems.
