  • Rig Floor Equipment: Quintuplex mud pump enables efficient transfer to hydraulic horsepower

    The Ellis Williams Engineering Company (EWECO) is on the verge of showcasing its next generation of pumps in the 2008 OTC show. Their expanded offering is for a “Quintuplex” (five cylinder) high-horsepower (1,700, 2,200 and 3,000) continuous-duty mud pump with their patent-pending design of a crankshaft driven by internal herringbone gears. As is the norm with all of the company’s designs, roller bearings are in every position with a true eccentric-type, fully balanced, crankshaft. The crankshaft will have a piston firing order of 1-3-5-2-4 with four main bearings, which isolates all crankshaft loads, unlike a typical triplex, where two eccentrics are always fully loaded between two mains at any given time. The pinion shaft will be driven from both sides by electric motors much like a conventional triplex pump, which allows for true interchangeability on every drilling rig.
