Series B71U & B76U are single helical coil spring seals developed for dirty media and clogging type applications. Torque transmission from retainer shell to seal ring is done through drive lugs. All components are held together by a snap ring which helps in easier installation and removal. As all parts are interchangeable, one can convert series B71U & B76U by changing only the seal ring and the secondary seal. This concept is ideal for stock rationalization.

Series BSP 150 & BSP 155 are single helical coil spring, bi-directional seals developed for dirty media and clogging type applications. Torque transmission from drive collar to spring holder and seal rings is done through sturdy drive lugs. The PTFE double V-packing are spring energized to give perfect dynamic sealing. As all parts are interchangeable, one can convert series BSP 155 to BSP 150 by changing only secondary seal. This concept is ideal for stock rationalization.

Series B81U & B86U are multiple spring units developed for universal application. Their compact design permits their use in all types of centrifugal pumps. Torque transmission from retainer shell to seal ring is done through drive lugs. All components are held together by a snap ring which helps in easier installation and removal. As all parts are interchangeable, one can convert series B81U & B86U by changing only the seal ring and the secondary seal. This concept is ideal for stock rationalization.

Series B110V & B115V are single wave spring seals suitable for most general application. Major advantage of these seals is due to use of single wave spring. It is of compact design with reduced axial length. These seals can also be used in dirty application as spring clogging does not occur. Torque transmission from retainer shell to seal ring is through drive pin.

Series B72 & B72L are single coil springs with electrometric bellows for water, Oil and light duties. This seal has self aligning feature which compensate abnormal shaft end play and run out, which leads to improved service life. Electrometric bellow protects shaft and sleeve from fretting. Drive to the seal faces is given through notches – provided on retainer. Seal can be repaired in field with minimum spares minimizing the down time cost.

Series BSR 100 is single coil spring rubber bellow seal used for water and oil containing soft slurries. This seal is mainly used in waste water treatment plant i.e. for sewage application. Seal 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 coil spring and spring holders. Due to single coil spring, seal will not get clogged in effluent containing particles.

Series BSR 200 & BSR 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. Seal has self aligning feature which compensates abnormal shaft end play & run-out, which leads to improved service life. Elastomeric bellow protects 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.

Series BN72 is single coil spring with elastomeric bellow, designed for water, oil and light duties. This seal has self aligning feature which compensate abnormal shaft end play and run out, which leads to improved service life. Elastomeric bellows protect shaft and sleeve from fretting. Drive to the seal faces is given through notches – provided on retainer. Seal can be repaired in field with minimum spares minimizing the down time cost.

Series BLSP 160 & BLSP 165 is single helical coil spring, bi-directional seals developed for dirty media and clogging type applications. Torque transmission from drive collar to spring holder and seal rings is done through sturdy drive lugs. The PTFE double V-packing is spring energized to give perfect dynamic sealing. As all parts are interchangeable, one can convert series BLSP 155 toBLSP 150 by changing only secondary seal. This concept is ideal for stock rationalization.

Series B3U is a single conical helical spring, unbalanced seal with '0' ring as secondary sealing member. Various seal face materials and elastomers can be offered for wide service application. As the torque transmission is done by conical helical spring these seals are dependent of the direction of rotation. Direction of rotation is seen from the drive end of the shaft. Clockwise rotating shaft requires right handed spring and anticlockwise rotating shaft requires left-handed spring. For easier fitting, the conical helical spring should be pushed on the shaft with a twisting motion in the sense of the spring unwinding. This movement enlarges the diameter of the spring, enabling easy fitment.
