The Oilwell 8-P-HD is a heavy-duty mud pump with factory-listed ratings of 800 HP rated input power, an 8-1/2 in stroke length, a rated speed of 160 SPM and a max working pressure of 160 PSI, across a range of liner bores. Its power end is an all-in-one welded steel frame with heavy-duty reinforcement, giving the rigidity needed to keep drivetrain components precisely aligned under extreme loads. A herringbone gear set provides smooth, quiet power transmission and naturally offsets axial thrust, which reduces bearing wear. The crankshaft, the core of the power end, is forged from quality alloy steel and put through a strict heat treatment process for strength, toughness and fatigue resistance. We support the 8-P-HD with replacement fluid-end wear parts for operators in Canada, the United States and international oil and gas markets.
