A part of National Oilwell Varco, the Mission line of centrifugal pumps are equipped with innovative features to match the demanding nature of routine, corrosive and abrasive applications. Because of the need for a low pressure mud system, Mission 1780 Type W centrifugal pumps were introduced in 1950s to replace duplex pumps. The aim was to apply a high quality centrifugal pump with concentric systems that allowed for abrasive fluids to be mixed and transferred thereby lowering the initial and maintenance costs of drilling. As a result, centrifugal pumps with low pressure mud systems such as Mission 1780 Type W became the industry standard.

As well depths increased, so was the need for heavier mud weights and centrifugal pumps that could withstand greater horsepower load. This led to the launch of Mission Magnum- a centrifugal pump.

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).

I am 100% satisfied with my duplex. It is amazing how much it pumps. It does everything I need it to do and I will recommend Centerline mud pumps to anyone.

It looks like my Centerline monopump is going to fill my needs.  In our work it is desirable to have volume and pressure for fast Geothermal boreholes.

Our Centerline Triplex Pump has been in use for almost 2 years now with no maintenance of any kind. We are using the triplex setup to do large diameter irrigation wells along the Kansas and Missouri River. They get the job done without compromise in any way. When I go out to work I can count on the Centerline Triplex to be ready and dependable.
