Product Overview
The Danfoss JR R S65C LS 25 20 NN N 3C2N9 A8N NNN JJJ NNN (Material Number: 83025913) is a high-performance axial piston pump engineered for demanding industrial hydraulic systems. Featuring a robust swashplate design, this pump delivers precise variable displacement control with exceptional volumetric and mechanical efficiency. The “LS” designation indicates a Load Sensing control, enabling the pump to adjust flow output based on real-time system demand, significantly reducing energy consumption and heat generation. With a nominal displacement of 65 cm³/rev and a maximum continuous pressure rating of up to 250 bar, this pump is ideal for high-pressure, high-flow applications requiring precise actuator control and reliable continuous duty operation.
