Type VT- 9 / VT - 9W are multi spring, pusher type unbalanced seals used for universal 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, VT- 9 can be converted to VT - 9W by just changing the seal ring and the secondary member.
