Abstract
One or more techniques and/or systems are disclosed for a positive displacement pump. The pump includes a pump housing having an inlet and an outlet. An internal gear assembly is arranged along a fluid pathway between the inlet and outlet and includes a shaft, a rotor gear, and an idler gear. The rotor gear is operably coupled to a first end of the shaft. A first bearing is arranged around the shaft. The seal holder plate is arranged between the first bearing and the first end of the shaft. A first sealing element is concentrically arranged between the shaft and the seal holder plate to seal and isolate the first bearing from fluid traveling between the inlet and the outlet. The first bearing, the seal holder plate, and the first sealing element are arranged in a packing box portion of the pump housing that is isolated from the fluid.
