Product Overview
The Danfoss 83022179 axial piston pump, designated within the JR R S51B LS 26 20 NN N 3 S1BF A2N FFF JJJ NNN series, is a high-performance variable displacement pump engineered for demanding industrial hydraulic systems. Utilizing a robust swashplate design with axial pistons, this pump delivers precise displacement control and consistent pressure output across a wide operating range. The LS (Load Sensing) control variant enables the pump to adjust flow output based on real-time system demand, significantly reducing energy consumption and heat generation in continuous-duty applications. With a nominal displacement of 26 cm³/rev and a pressure rating suitable for high-pressure industrial circuits, this model is a direct-fit replacement for OEM installations requiring reliable, efficient hydraulic power.
