Product Description
A11VLO 260 Axial Piston Variable Pump (DR / DRS Control)
Product Overview: The A11VLO 260 series is a premium swashplate axial piston variable pump engineered for open-circuit hydraulic systems in heavy-duty mobile machinery and industrial plants. With a substantial 260cc displacement and a nominal pressure rating of 350 bar, it serves as a robust power source for excavators, mining rigs, and large presses. Featuring advanced DR (Pressure Control) and DRS (Load Sensing) architectures, this series ensures exceptional dynamic response and maximum energy efficiency.
Key Technical Advantages:
Sophisticated Control Logic: The DR configuration automatically modulates displacement to maintain a preset system pressure. The DRS version provides Load Sensing capability, adjusting flow and pressure based on actuator demand to drastically minimize energy dissipation and heat generation.
Heavy-Duty Durability: Designed for continuous high-pressure operation (350 bar nominal / 400 bar peak), utilizing reinforced swashplates and precision-hardened pistons to ensure a long 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.
Through-Drive Capability: Features a rugged through-drive shaft, allowing for the tandem mounting of additional pumps to power auxiliary hydraulic circuits seamlessly.
Specific Models and Technical Parameters: This product range includes specialized configurations such as the A11VLO260DR/11R-NZD12K02 and A11VLO260DRS/11R-NZD12N00. Key specifications include a 260 cm³/rev displacement, SAE standard mounting patterns, specialized NZD12K02 and NZD12N00 seal arrangements, and a stable working pressure range of 31.5 MPa to 35 MPa.
