Danfoss K Series Open Circuit Variable Displacement Piston Pumps

Product Overview: The Danfoss K Series (K Frame) piston pump is a high-performance variable displacement unit engineered to meet the demanding requirements of modern mobile and industrial hydraulic systems. This series is renowned for its exceptional reliability, ultra-low noise levels, and superior power density. This selection features core high-specification models: K045DPC17NN… (45cc with Pressure Compensated Control) and KRR038CRP212… (38cc with precision remote control). The K Series pumps provide rapid response under fluctuating loads, making them the premier choice for excavators, material handling equipment, forestry machinery, and industrial power units.

Key Technical Advantages:

• Advanced Control Solutions:

  • DPC (Pressure Compensated Control): Automatically adjusts displacement based on load to maintain constant system pressure, minimizing energy loss.

  • CRP (Control with Remote Port): Supports remote pressure adjustment, enhancing system integration flexibility.

• Robust Engineering: Reinforced rotating groups and high-capacity bearings ensure long-term operation in harsh environments, significantly lowering the total cost of ownership.

• Low Noise Characteristics: Optimized valve plate designs and housing structures drastically reduce pulsations and operating noise, improving the operator environment.

• Compact Footprint: Small installation envelopes provide greater layout flexibility, making it easy to integrate into tight machine compartments.

• Target Applications: Heavy-duty forklifts, agricultural tractor hydraulics, mobile cranes, road maintenance equipment, and general industrial hydraulic stations.
