Abstract: A gear pump having double-helical gears with bearing assembly seals and gear end seals which provided double seal interfaces between the pump cavity and bearing cups having disposed therein bearing assemblies for supporting pump shafts for rotation. The double seal interfaces preclude pumped fluid, particularly contaminated fluid including entrained abrasives from making contact with the bearing assemblies. An adjustable packing seal mechanism, a gear gap adjustment mechanism, a fluid pressure relief system, and pump heat exchanger features are also disclosed.

Abstract: A gear pump for pumping a fluid while adjustably controlling a gap between gears and end plates of the gear pump housing. The gear gap is controlled by a gear gap adjustment mechanism operably associated with a gear shaft to move the gear and shaft along a longitudinal axis of the shaft. The gear pump can also include a removable and replaceable friction shield to adjust the gap between the gear and the end plate. The gear pump can further include a dynamic shaft seal assembly for adjusting the sealing about the shaft.
