The Lewco W-250-C is a triplex mud pump rated at 250 HP input power, with a 5 in stroke and a rated speed of 400 SPM. Factory data lists a maximum working pressure of 5000 PSI and a maximum flow of 327 GPM; listed combinations include 5 in liners at 327 GPM and up to 1540 PSI, 4-1/2 in liners at 265 GPM and up to 3030 PSI, and 4 in liners at 209 GPM and up to 5000 PSI. The frame is a precision-manufactured double-wall welded steel structure with internal stiffeners and gusset plates, stress relieved after welding, and the pump is supplied on a heavy-duty oilfield skid mount. The crankshaft is a one-piece forging machined from high-nickel, high-chromium modified 4340 alloy steel, giving it a superior grain structure and fatigue strength.
