Danfoss JRR Series Pump | JRRS45, 83026828, 83026829 | 45cc Closed Circuit Piston Pump

Danfoss JRR Series (JRRS45) Closed Circuit Variable Piston Pump

Product Overview: The Danfoss JRR series is an advanced variable displacement pump range engineered for medium-power Closed Circuit hydrostatic systems. This showcase highlights the JRRS45 model (Part Numbers: 83026828 / 83026829), featuring a 45cc displacement with an integrated charge pump and multi-functional valve group. As a key member of the J-Frame family, this pump is renowned for its compact installation footprint and superior power density, providing precise and smooth tractive effort for mobile machinery.

Key Technical Advantages:

• High-Performance Closed Circuit System: Specifically designed for medium-duty travel drive applications. Rated for a continuous operating pressure of 310 Bar (4500 PSI), offering exceptional resilience against transient pressure spikes.

• Intelligent Control Modulations (BLS): Featuring BLS load sensing or hydraulic servo logic, ensuring that pump torque and flow output are synchronized with machine load in real-time for optimized fuel efficiency.

• Highly Integrated & Compact Design: The pump housing integrates check valves, pressure limiters, and charge functions into a single unit, significantly reducing external plumbing, minimizing potential leak points, and streamlining installation space.

• Durability & Extended Service Life: Constructed with reinforced rotating groups and precision balancing mechanisms, ensuring peak volumetric efficiency even during frequent reversals and speed modulations.
