Danfoss JRL Series Open Circuit Axial Piston Variable Pumps

Product Overview: The Danfoss JRL series is a range of high-performance axial piston variable displacement pumps engineered for efficient open-circuit hydraulic systems. This series spans key displacements including JRL045 (45cc), JRL060 (60cc), and JRL075 (75cc). Featured models like the JRL060B LS 25 20 NN N 3 C3N2 A8N stand out due to their integrated LS (Load Sensing) control logic. The JRL series dynamically modulates flow and pressure based on real-time actuator demand, significantly reducing energy waste and system heat. It is the premier power choice for rotary drilling rig heads, concrete pump trucks, truck-mounted cranes, and industrial Hydraulic Power Units (HPU).

Key Technical Advantages:

• Precision Load Sensing (LS): Through the integrated LS compensator, the pump automatically senses load pressure to deliver exact flow requirements, greatly enhancing the operational smoothness of multi-valve systems.

• High Power Density & Compact Design: An optimized cylinder block allows the JRL series to maintain high power output within a smaller footprint, facilitating easy installation in cramped chassis spaces.

• Superior Suction Performance: Specifically optimized for open-circuit designs, featuring a high rated speed limit to effectively mitigate cavitation risks during high-flow conditions.

• Quiet Operational Profile: Utilizes noise-suppression valve plate technology, maintaining low decibel levels even under full load to meet modern acoustic environmental standards.

• Rugged Industrial Build: Equipped with heavy-duty bearings and wear-resistant piston groups to ensure an extended service life in harsh construction site environments.
