Abstract: A dual cylinder positive displacement pump is used to move drill cuttings. The pump may include one or more of a self-sealing wear ring member/wear plate member interface, stainless steel pumping cylinders, and a hopper with an inclined surface.

Abstract: A method of assembling a dual cylinder positive displacement drill cuttings pump is provided. The method includes providing a hopper including a front end, a generally open rear end with a generally barrel-shaped sidewall extending therebetween to provide a generally barrel-shaped hopper volume, and an inlet port extending through the barrel-shaped sidewall for delivering material into the generally barrel-shaped hopper volume. A rear hopper wall is provided that includes first and second pumping cylinder openings that are spaced apart from each other and at a common elevation from a bottom of the rear hopper wall. An installation configuration for the drill cuttings pump is identified, including a hopper infeed angle. Based upon the identified hopper infeed angle, the hopper is located relative to the rear hopper wall such that an axis of the inlet port of the hopper is positioned substantially at the hopper infeed angle. Then, the hopper is connected to the rear hopper wall.
