Danfoss JRRS75 Variable Oil Pump
Danfoss JRRS75 is a high-performance axial piston pump, belonging to the product line of Danfoss Power Solutions, designed specifically for high-pressure hydraulic systems. This pump adopts a slanted disc structure, which has the characteristics of high efficiency, long service life, and low noise. It is widely used in industrial machinery, construction equipment, agricultural machinery, and ships.
Main features
1. High voltage and high efficiency
-The working pressure can reach 350 bar (peak pressure is higher), with high volumetric efficiency, suitable for high power density applications.
2. Modular design
-Flexible configuration of multiple control methods (such as pressure compensation, load sensitivity, electric proportional control, etc.) to adapt to different system requirements.
3. Low noise and low vibration
-Optimized fluid dynamics design reduces pulsation and noise, enhancing operational comfort.
4. Long lifespan and reliability
-High quality materials and precision manufacturing processes ensure durability under harsh working conditions.
5. Wide compatibility
-Seamless integration with Danfoss series valves, motors, and other components simplifies system design.
