Product Description
Rexroth A11VLO190 & A11VLO280 Series Heavy-Duty Variable Pumps
Product Overview: The Rexroth A11VLO series features swashplate axial piston variable pumps specifically engineered for Open Circuit high-pressure systems. This series includes both the established 190cc models and the high-performance 280cc (Series 41) units. Featuring the optimized L-specification (Self-Priming) suction design, the A11VLO maintains superior suction performance even at high rotational speeds. Integrated with LG1S power control or DRS Load Sensing, these pumps provide precise power distribution and exceptional energy efficiency for heavy machinery.
Key Technical Advantages:
Superior Self-Priming (L Spec): The enhanced suction flow path allows the pump to operate stably at higher speeds without a charge pump, effectively mitigating cavitation risks during high-flow delivery.
Advanced Control Modulation (LG1S/DRS):
LG1S Models: Feature constant power regulation with integrated pressure compensation, automatically modulating displacement to prevent engine overloads.
DRS Models: Integrate Load Sensing (LS) and pressure compensation, modulating flow based on real-time demand to drastically reduce energy waste and heat generation.
Cross-Series Heavy-Duty Performance:
A11VLO190: Proven Series 11 design supporting rated 350 Bar pressure, widely used in construction machinery.
A11VLO280 (Series 41): Utilizing Rexroth’s latest Series 41 design, providing higher power density and an optimized rotating group structure.
Robust Thru-Drive Capability (K02): Equipped with thru-drive functionality, supporting tandem mounting of secondary pumps to optimize multi-circuit hydraulic layouts.
Detailed Models & Technical Parameters:
Core Models: A11VLO190 (Series 11), A11VLO280 (Series 41).
Detailed Config Codes: A11VLO190LG1S/11R-NZD12K02-S, A11VLO280DRS0A00/41MRVE4T3E4T30-0.
