Cooper unit exchange (UX) parts save operating expenditures, minimize equipment downtime, increase reliability, and reduce material waste to limit environmental impacts. Through our service shop network, we take in and evaluate used cores and remanufacture them to our exacting standards. We also use the service shops to warehouse completed cores and stage them close to customers’ needs. Brands that we maintain UX parts for include: Cooper-Bessemer, Superior, Clark, Ingersoll Rand, and Worthington. Parts include power cylinders and liners, power cylinder heads, master rods and articulated rods, crossheads and guides, and water and oil pumps. Additionally, Cooper has complete Superior and Waukesha UX engines.

proven results

COOPER CASE STUDY: Our St. Rose service center completed a successful overhaul of a Cooper-Bessemer GMVR-12 engine-compressor for a customer in Florida. The overhaul included the rebuilding of power heads, pumps, art rods, piston pins, pin carriers, and compressor cylinders. Our Cooper service team was diligent in inspecting, re-qualifying, and rebuilding the unit to our O.E.M. standards. Southeast Regional Director, Greg Penzato, stated: “Our St. Rose shop has a lot of experience rebuilding the large-bore Cooper and non-Cooper integrals. It’s a pleasure working on these great engines and satisfying the customer in the process.”
