• Our History

    We began serving the oil and gas industry in 1916, creating a rich history that would one day be a legacy of National Oilwell Varco (NOV).

    Wheatley Pump and Valve opened for business on March 1, 1916, in Kansas City, Missouri, and Gaso Pumps was also incorporated in Tulsa, Oklahoma that same year. Then, in 1989, the two companies merged together as Wheatley/Gaso and later joined Mission products in 2000 within the NOV family. These products are the standards by which our competitors measure their products

    As the industry-leading manufacturer of reciprocating pumps, we offer a large array of field-proven, reliable piston and plunger pumps backed by a global technical support team. Our product line includes intermittent duty pumps available in single-acting and double-acting models. With simplex, duplex, triplex and quintuplex designs with input horsepower ranges from 2 to 2,600, we have an option that can meet your needs in nearly every application.

    We are the industry leader in the design, manufacturing and distribution of fluid-end expendables, as well as the industry innovator of premium pump expendables including carbide plungers, spherical valve assemblies and premium plunger packaging.

    Our reciprocating pump brands include National, Oilwell, Wheatley, Gaso, Bear and MSW. Our Mono and Moyno progressing cavity pumps also have an 85+ year history that further broadens the range of conditions we serve for our customers.

    Today our pumping product line is global, with plunger pumps operating on every continent including Antarctica. We also have the world’s largest pump distribution network, and we carry the industry’s largest array of single-acting quintuplex pump models available.

    Our pumping products have been a promise to our customers for 100 years and will continue to bring value to the industry for many years to come.
