The company began rebuilding plastic and rubber molding machines before shifting into the oil and gas industry in 2010, and now combines custom machining with self-developed fluid-end reconditioning processes. Its FlowMaster fluid ends are a signature product, while repaired fluid ends are reported to average more than 1,000 hours after service.
