- Economical to assemble as the complete dismantling of the equipment is not necessary to install the seal
- Reduces down time due to ease in installation
- Rugged seal construction
- Distortion of the seat is avoided by mechanical decoupling of the clamping ring
- Ease in installation due and no modifications are required because the seal is located outside of the stuffing box
- Due to the stationary design and the elastic seat mounting a high tolerance of shaft deflections can be accommodated
- Low leakage is achieved by the elimination of secondary seals which eliminates leakage paths between split components
- Shaft is protected by uniform torque transmission through the clamping ring which prevents damage caused by set screws.
- Springs are product protected to avoid contamination and clogging
