THOMAS Coupling

We provide also a stock list for Thomas Coupling which is info fo using with some info as follow:

"For heavy-duty applications with higher peak load requirements, Tenneco tested Thomas Series 71 disc couplings on eight motor/pump units operating above 3600 RPM. Despite two coupling failures caused by pump and alignment problems, the pumps with Thomas couplings showed average vibration levels 58% lower than the same units with gear couplings after six months of operation. Repairs were down 58% as well, according to Polk, resulting in a total annual savings of more than $80,000 for the test units. Maintenance costs are lower as well, since the Thomas couplings need no lubrication and can be inspected while operating by using a strobe light.

Most of the couplings were left in place following the test period. During the second year, the applications with Rexnord Omega couplings showed a 73% reduction in coupling-related pump repairs. Over the same period, the Thomas coupling applications exhibited a 53% reduction in coupling-related repairs. Polk concludes that these findings establish the ability of the couplings to perform over lengthy periods.

As a result of the tests, the Tenneco Maintenance Department recommended a change to the Rexnord Omega urethane elastomer couplings on all motor-driven pump applications up to 400 HP and 3600 RPM and installation of Thomas disc-type couplings on applications greater than 400 HP or at speeds above 3600 RPM."
