American Manufacturing Company

American Manufacturing Company (American Mfg Co) is a U.S.-based manufacturer of mud pumps and aftermarket replacement parts serving the Oil & Gas, Mineral Exploration, Geothermal, and Water Well drilling industries. Founded in 1990 and headquartered in St. Joseph, Minnesota, with a second facility in Houston, Texas, the company has produced high-quality Oil & Gas mud-pump spare parts for more than 25 years. American Mfg was the first non-OEM manufacturer in the USA to hold API 7-K, API Q-1, and ISO 9001:2015 certifications, and it guarantees that all of its parts are 100% identical, interchangeable, and at least equal in quality to the competing OEM brand they replace. Capabilities include fluid end rebuild kits, pistons, liners, valves, seats, springs, fluid end modules, gear end rebuild kits, and complete duplex and triplex mud pumps (including proprietary designs such as the American AXG, FF-AXFZ, AL0918BCD, AL1122D and AW1122BCD pumps). The company's engineering staff is able to legally reverse-engineer customer-supplied sample parts and place them into production within weeks using 30 CNC machining centers, 5 extruders/presses, 5 manual machines for small specialty items, state-of-the-art CMM quality control equipment, and in-house industrial heat-treating ovens and chillers. American Mfg Co supplies replacement parts for a wide variety of OEM mud pumps — including Gardner Denver, George E. Failing, and other legacy brands — and maintains over $1,000,000 of interchangeable pump parts in stock, enabling same-day shipment on most orders.
