80 HP tractor external gear pump  

Introduction of 3.5EPF**  3.5EPF** series external gear pumps have a floating busing with automatic axial clearance compensation. Gear pumps are positive displacement pumps, meaning they use expanding and contracting chambers to move fluids at a fixed rate. Specifically, they are rotary positive displacement pumps, which utilize a rotating mechanism or assembly to cause this contraction and expansion. To learn more about selecting different types of positive displacement pumps, visit the Positive Displacement Pumps Selection Guide page on GlobalSpec. Spur gear pumps have the advantage of being well balanced and can run at high speeds often making them a better choice for thin fluids. Specifications Dimensions
