Product Description
Rexroth A11VLO Series High-Pressure Axial Piston Variable Pumps
Product Overview: The Rexroth A11VLO series is the gold standard for heavy-duty axial piston variable displacement pumps designed for open-circuit mobile machinery. Known for its exceptional power density and extreme reliability, this series features prominent models such as A11VLO190LE2S/11L-NSD12K02P and A11VLO190LE2S/11L-NSD12K72P, offering a geometric displacement of 193 cm³/rev. Utilizing a proven swashplate architecture, these pumps deliver precise flow modulation at a rated pressure of 350 Bar. Their superior suction characteristics and through-drive capabilities make them the premier choice for concrete pump main pumps, rotary drilling rigs, and large crawler crane hydraulic systems.
Key Technical Advantages:
LE2S Precision Control: Integrates electronic proportional control with pressure cut-off, matching optimal power output to engine speed and system load for maximum fuel efficiency.
Extreme High-Pressure Durability: Rated for continuous operation at 350 Bar (5100 PSI) with peak capabilities up to 400 Bar. Engineered with reinforced rotating groups to withstand heavy-duty shock loads.
Superior Suction Performance: The streamlined flow path design allows for higher rated speeds, ensuring reliable volumetric efficiency even during cold starts or long-distance suction conditions.
Quiet Operation & Longevity: Features Rexroth-patented noise reduction and heavy-duty roller bearings, ensuring stable 24/7 performance in harsh environments and extending service intervals.
100% Through-Drive Capability: Supports full torque through-drive for tandem mounting of auxiliary or additional pumps, simplifying complex multi-circuit hydraulic layouts.
Detailed Models & Parameters:
Core Series: Rexroth A11VLO Series 11 (Mobile).
