New Kop-Flex Service Program Recertifies Used, High-Performance Couplings to API 671 Standard

Emerson’s Power Transmission Solutions introduces a new program for restoring used high-performance couplings to like-new condition, certified to API 671, with a full original factory warranty. Ideal for high-speed (>1,800 rpm) couplings used on turbomachinery, compressors, pumps and marine drivetrains, the Kop-Flex recertification program is a low cost alternative to replacement of a coupling, for just 50 to 60 percent of the cost for a new unit. “It is also an excellent option for adding a low-cost spare to a plant’s stores,” said Dan Phillips, Kop-Flex Global Manager, Metals Industry Service. “This is not a repair program, but more like factory service for a high-mileage car, except you get a new-car warranty and performance at the end.” The recertification program applies to all Kop-Flex disc, diaphragm and gear couplings, and the company’s four global service centers provide processing of most couplings in four weeks or less.

The program includes comprehensive mechanical/metallurgical evaluation with MPI and dye-penetrant testing; updating to all current standards; glass bead blasting and hand polishing; replacement of wear parts such as disc packs, shims, and fasteners; precision dimensional and TIR measurement; rebalancing to original API 671 or 610 specs and return shipping in a custom crate. Glass bead blasting eliminates the need for machining/metal removal that might cause a need for shimming during reinstallation.

The recertification program requires return of the entire coupling structure. Couplings not originally produced by Kop-Flex are accepted on a case-by-case basis for limited services.
