Multi Spring Seal – P-93/P-94

P-93/P-94 mechanical seals are multi spring, pusher type balanced seals suiting high pressure applications. The seals are compact 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, P-93 can be converted to P-94 by just changing the seal ring and the secondary member.
