Spring Seals

Series ASS O & ASS U 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 ASS O & ASS U by changing only secondary seal. This concept is ideal for stock rationalization.

This is a single conical helical spring, unbalanced seal with 'O' 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.

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 covert Series AIB 70 to AIB 75 by changing only the seal ring and the secondary seal. This concept is ideal for stock rationalization.

Single wave spring seals suitable for most general Major advantage of these seals is due to use of single wave spring it is of compact reduced axial length. These seals can also be used in dirty application as spring clogging occur. Torque transmission from retainer shell to seal ring is through drive pin.

This is designed to supply clear flushing fluid for lubrication to mechanical seal in seal chamber. This is fitted in between pump discharge and seal flush port line, to remove abrasive particles which can cause damage to mechanical seal and reduce its recommended operational life. Due to centrifuging action of the fluid, cyclone is generated in the cyclone separator and 80% of abrasive particles are separated and sent back to pump section.
