Type LMS-80 are multi spring, pusher type unbalanced seals used for universal applications. These seals are compact in design suiting all types of rotating equipment, pumps and mixers. Drive lungs in the retainer will provide torque transmission and reduce slippage on shaft and sleeve. A snap ring holds all components together, helping easy installation. The parts are interchangeable. LMS-80 can be converted to LMS-83 by just changing the seal ring and the secondary member.
