Product Overview
The Danfoss 83025913 axial piston pump, designated JR R S65C LS 25 20 NN N3C2N9 A8N NNN JJJ NNN, is a high-performance variable displacement pump engineered for demanding industrial hydraulic systems. Built on Danfoss’s proven swashplate axial piston platform, this unit delivers precise displacement control and consistent volumetric efficiency across a wide pressure range. The “LS” designation indicates load-sensing control, enabling the pump to match flow output to system demand, reducing heat generation and improving overall energy efficiency. With a nominal displacement of 65 cm³/rev, this pump is well suited for medium-to-high power circuits requiring responsive, pressure-compensated performance in continuous-duty applications.
