Abstract
A progressing cavity pump system including a feeder assembly including a hopper for receiving material to be pumped therein. The feeder assembly includes an auger housing receiving an auger therein. The auger housing has an underlying portion positioned generally below the hopper and having a radial opening open to the hopper, and an extension portion which is generally radially closed. The extension portion and the underlying portion are of a one-piece, seamless construction. The pump system further includes a progressing cavity pump including a rotor, a stator, an inlet and an outlet. The rotor is rotationally disposed inside the stator such that rotation of the rotor causes material in the pump to be pumped from the inlet toward the outlet, and the inlet is fluidly coupled to the extension portion.
