Ashish Seals is one the of the major Reverse Balanced Mechanical Seal manufacturers, suppliers and exporters in Mumbai India. We are ISO 9001-2015 certified reliable manufacturer of Reverse Balanced Mechanical Seals that is designed to handle abrasive or corrosive media. As the metal components of this kind of seal do not come in contact with the media to be sealed, it is widely in demand. The offered mechanical seal is compact in design; hence neither axial nor radial extra space is essential for its installation. Such seals are used to handle hydrocarbons, corrosive chemicals, general & light chemicals.

Working Principle

Reverse Balanced Mechanical Seal is externally mounted and are multi coil spring seals. Liquid pressure is used for closing the seal faces. Thus, it is very useful in vacuum and high pressure applications. As it eliminates the shaft step or sleeves for balancing, this makes it a unique seal. It can be exceptionally useful light corrosive and contaminated liquid. The metal does not come in contact with the media. Such seals eliminate the elastomer’s movement. Hence it reduces fretting effect on shaft efficiency.
