Flowserve is one of the world's largest makers of the pumps, mechanical seals and valves that move and control fluids inside refineries, chemical plants and power stations. Roughly half its ~$4.6B revenue is high-margin aftermarket parts and repair on a vast installed base — serviced through a global network of Quick Response Centers.

The chain, in simple terms

Metal castings, motors and seal components come in; Flowserve machines them into engineered pumps, mechanical seals and valves; and those move fluids inside refineries, chemical plants, power stations and water utilities. The real prize is the decades of parts and repair afterward, delivered through its global Quick Response Centers.
