Description::
The Sepco® OSS is an external mounted, single spring component seal designed primarily for installation on positive displacement pumps. Ease of installation and maintenance makes the seal excellent for sealing products that polymerize. The OSS can be designed to handle up to 1/4” shaft deflection and 1/8” end-play making it also ideal for installation on augers, mixers, agitators and reactors.
Aplications:
Hydraulically Balanced
The OSS is reverse-balanced to prevent catastrophic leakage from face separation caused by stuffing box pressure surges. Hydraulic load is reduced at elevated pressures resulting in cooler operation and long-term reliability
