Cartridge Unbalanced Double Mechanical Seals

LPS-185-U & LPS-188-U

LPS-185-U & LPS-188-U series are double acting cartridge design unbalanced Mechanical Seals suitable for Slurries, Sludge’s, Syrup, Water, Oil & Chemicals used in low & high pressure pumps. These seals are independent of direction of rotation, pre assembled cartridge unit easy to install with different PCD’s pumps due to slots provided on gland plate and these seals can be offered in balanced and unbalanced configuration. As all parts are Interchangeable, one can convert this series LPS-185-U to LPS-188-U by changing only the dynamic ring and the secondary seal, this principle is ideal for stock rationalization, this seals are comfortable to use in wide range of application.
