Product Description

Danfoss KRR Series Axial Piston Variable Displacement Pumps

Product Overview: The Danfoss KRR Series (formerly Sauer-Danfoss K Frame) is a high-performance variable displacement piston pump engineered specifically for open-circuit hydraulic systems. As a compact and robust axial piston unit, the KRR series provides precise flow regulation by adjusting the swashplate angle. This page features precision-configured long-code models: KRR038CLS2020NNN3C2AGA6NPLBNNN and KRR045DLS2122NNN3C2NKA6NKNBNNNNNN. Renowned for its reliability and versatile control options, this series is the ideal power core for road cold millers, pavers, combine harvesters, concrete pumps, and auxiliary hydraulic systems in construction machinery.

Key Technical Advantages:

  • Elite Power Density: The K Frame design maximizes output pressure and displacement ratios within a restricted installation envelope, significantly reducing total vehicle weight.

  • Advanced Load Sensing (LS): The LS configuration in the model code denotes high-sensitivity load-sensing control, automatically adjusting flow to match load demands, which minimizes heat generation and energy loss.

  • Heavy-Duty Pressure Rating: Rated for a nominal pressure of 260 Bar with peak capabilities reaching 350 Bar, ensuring extended service life under frequent high-load cycles.

  • Low-Noise Operation: Optimized valve plate designs and a high-rigidity housing structure effectively reduce fluid pulsation and mechanical noise during high-pressure operation.

  • Rapid Response Dynamics: The variable displacement mechanism reacts instantaneously to operator commands, enhancing the fluid continuity and overall responsiveness of the machine.

  • Target Applications: Agricultural harvesting systems, construction auxiliary functions, forestry equipment, and industrial power units.
