Series AMROU/AMRWU is multi spring, pusher type unbalanced seals used for universal application. The seals are compacts in design suiting all types of rotating equipments, pumps and mixers. Drive lugs in the retainer will provide torque transmission and reduce slippage on shaft and sleeve. A snap ring holds all components together, helping in easy installation. The parts are interchangeable, PTROU can be converted to PTRWU by just changing the seal ring and the secondary member.
