Product Overview
The Danfoss JR R S75C LS 21 20 NN N 3 C3NE A8N NNN JJJ NNN (Part No. 83026581) is a high-performance axial piston pump engineered for demanding industrial hydraulic systems. Featuring a swashplate design with a bent-axis rotary group, this pump delivers exceptional volumetric efficiency and high-pressure capability in a compact, robust package. The model designation “LS” indicates load-sensing control, enabling precise flow-on-demand operation that reduces energy consumption and system heat generation. With a nominal displacement of 75 cm³/rev, this pump is well-suited for continuous-duty applications requiring reliable pressure and flow control. The “C3NE” control variant provides advanced pressure and flow compensation, making it an ideal choice for complex hydraulic circuits in mobile and industrial machinery.
