Product Description
A11VLO 260 Axial Piston Variable Pump (LRDH1 / LRDU2 Control)
Product Overview: The A11VLO 260 series is a heavyweight benchmark in hydraulic power systems, engineered specifically for high-pressure open-circuit applications. Delivering a massive 260cc displacement and a nominal pressure rating of 350 bar, it serves as the primary driver for excavators, mining rigs, and massive industrial presses. Equipped with advanced LRDH1 (Hydraulic Stroke Control) and LRDU2 (Power Control with Unloading) architectures, this series ensures peak energy efficiency and robust performance by optimizing power distribution according to real-time load requirements.
Key Technical Advantages:
Sophisticated Power Management: The LRDH1 configuration provides exceptional hydraulic stroke limitation to prevent mechanical overload. The LRDU2 version includes an integrated unloading function, drastically reducing power loss and heat generation during system idle cycles.
Heavy-Duty Durability: Built for continuous high-pressure operation (350 bar nominal / 400 bar peak), utilizing reinforced swashplates and precision-hardened pistons to ensure an extended service life in extreme environments.
Superior Suction Performance: The fluid-dynamically optimized internal paths maintain high volumetric efficiency and significantly reduce cavitation risk, even at high rotational speeds, making it ideal for high-cycle industrial duties.
Through-Drive Capability: Features a rugged through-drive shaft, allowing for the tandem mounting of additional pumps to power auxiliary hydraulic circuits efficiently while maintaining a compact footprint.
Specific Models and Technical Parameters: This product range includes specialized configurations such as the A11VLO260LRDH1/11R-NSD12N00-S and A11VLO260LRDU2/11R-NZD12D02P-S. Key specifications include a 260 cm³/rev displacement, SAE standard mounting patterns, high-performance NSD12N00 and NZD12D02P sealing arrangements, and a stable working pressure range of 31.5 MPa to 35 MPa.
