NOV's Mission Magnum has been the most popular centrifugal pump in the drilling industry since the 1970’s because of its proven reliability, durability, and economical structure. 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
