Product Description
Rexroth A20VLO 190 Series Hydraulic Pump for Coal Mine Dump Trucks
Product Overview: The Rexroth A20VLO 190 series is a high-pressure, large-displacement axial piston pump specifically engineered for Coal Mine Dump Trucks, mega-mining haulers, and heavy-duty mobile equipment. As the powerhouse of mining hydraulic systems, its 190cc displacement and superior shock resistance make it the standard for hoisting and steering systems in off-highway wide-body trucks. Whether utilizing the DRS controlled A20VLO190DRS or the power-regulated A20VLO190LG1S, this series ensures robust performance in the harshest mining environments.
Key Technical Advantages:
Heavy-Duty Mining Control Logic: The model A20VLO190DRS/10R-NZD24N00 features DRS control (Pressure control with load sensing) for precise flow under varying loads. The A20VLO190LG1S/10R-NZD24K02-S variant offers LG1S power control, preventing engine stalls during peak hydraulic loads and optimizing vehicle fuel efficiency.
Tandem Design Capability: Utilizing a specialized swashplate architecture for dual-circuit systems, the A20VLO can simultaneously power both the tipping/hoisting mechanism and the steering system, offering high power density in a compact footprint.
Durability for Extreme Conditions: Built for high-dust and heavy-load coal mine conditions. Featuring reinforced swashplate bearings and high-performance seals, it supports rated pressures up to 350 Bar, effectively handling instantaneous pressure spikes during dumping operations.
Specialized Configuration (NZD24): Complies with NZD24 standard mounting flanges and K02/N00 shaft specifications, ensuring high-strength integration with mining machinery gearboxes.
Specific Models & Technical Parameters: This range includes core configurations: A20VLO190DRS/10R-NZD24N00, A20VLO190LG1S/10R-NZD24K02-S, and the full A20VLO190 series. Key specifications: 190 cm³/rev displacement; rated operating pressure of 35 MPa (350 Bar); peak pressure of 40 MPa (400 Bar); Clockwise (R) rotation; and standard Series 10 industrial/mobile grade architecture.
