Mechanical Seal Series

Model Number: AI 109 , AI 109L, AI 109/C, AI109L/C

Series AI 200 & AI 205 is single coil spring rubber bellow seal used for petrochemicals, Food processing, Pulp & Paper and other demanding applications. This seal is mainly used in compressors. Sea has self aligning feature which compensates abnormal shaft end play & run-out, which leads to improved service life. Elastomeric bellow protect shaft / sleeve from fretting. Drive to the seal faces is given through notches provided on retainer. Due to single coil spring, seal will not get clogged in effluent containing particles. Seal can be used for higher speed as well as for higher pressure. Seal can be repaired in field with minimum spares minimizing the downtime cost.
