Flowserve Corp
A global manufacturer of pumps, valves, mechanical seals, and automation gear, Flowserve supplies the heavy machinery that moves fluids through oil refineries, chemical plants, power stations, and water systems — and keeps that installed equipment running with aftermarket parts and service centers around the world. The company itself was formed in 1997 when pump maker BW/IP and valve maker Durco merged, taking a name that blends "flow" with "serve" to signal a focus on both products and service. Though the brand is young, its roots stretch back to Byron Jackson, a California inventor who founded his pump company in 1872, making Flowserve a home for some of the industry's oldest pump names.
