The Mission MAGNUM I has been engineered for the toughest jobs in drilling, production, well-servicing, and industrial applications. The revolutionary design of the MAGNUM I provides supreme-duty performance in all types of fluid pumping operations. Although it offers greater capacity and higher heads, the MAGNUM I remains the competitive pump of choice for aggressive applications. The MAGNUM I is more powerful, more durable, and easier to maintain than any conventional pump in use today. The Magnum has an open impeller design that contains wide-tipped vanes and a more tangential circumference of the suction allowing the pump to create a smoother flow pattern when handling abrasive fluids. The Magnum is available in Magnachrome, hard iron, stainless steel, and aluminum bronze fluid ends. The pumps can be unitized with electric motors, diesel engines, and hydraulic motors (horizontal, vertical, or close-coupled configuration). Also available, Horizontal and Vertical Close Coupled Magnum.
