Intelligent Electro-Proportional Control (EO2): The integrated electro-proportional valve enables precise and rapid remote control of the pump's swashplate angle via an electrical signal. This allows for seamless integration into modern machine control systems for optimal, energy-saving performance.
Extremely High Flow Output: With a large displacement of 500 cm³/rev, this pump is capable of generating very high flow rates to meet the substantial hydraulic power demands of large-scale equipment.
High Efficiency & Energy Savings: The variable displacement design ensures the pump delivers only the flow required by the system, minimizing energy waste, reducing fuel consumption, and lowering heat generation.
Robust Construction for Severe Duty: Built with heavy-duty components to withstand continuous operation at high pressures and under the most challenging conditions in mining, construction, and heavy industry.
Compact Design with High Power Density: Offers a favorable power-to-size ratio for its output class, facilitating integration into space-constrained engine compartments of large machinery.
This high-flow pump is ideally suited as the main hydraulic power source for:
Large Mining & Construction Machinery: Hydraulic systems for large excavators, mining shovels, heavy-duty wheel loaders, and drilling rigs.
Industrial Presses & Heavy Machinery: Main drive pump for large hydraulic presses, forging machines, rolling mills, and test rigs.
Marine & Offshore Equipment: Power source for deck cranes, winches, and other heavy shipboard machinery.
Specialized Heavy Transports: Hydraulic systems for large multi-axle transport vehicles (SPMTs).
