Abstract
A system includes a pump configured to transfer a granular material out of a hopper into a transfer pipe. The pump includes an upstream portion having an upstream helical flight and a downstream portion having a downstream helical flight. The downstream portion includes a tailpiece. An outer diameter of the downstream helical flight is less than an outer diameter of the upstream helical flight, a gap between the outer diameter of the downstream helical flight and an auger housing is greater than a gap between the outer diameter of the upstream helical flight and the auger housing, a thickness of the downstream helical flight is less than a thickness of the upstream helical flight, a surface of the downstream portion has a lesser coefficient of friction than a surface of the upstream portion, or a combination thereof.
