Series AMROB/AMRWB mechanical seals are multi spring, pusher type balanced seals suiting high pressure applications. 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; PTROB can be converted to PTRWB by just changing the seal ring and the Secondary member.
