Factory assembled and dynamically tested seal for steel, glass lined and SS mixers, agitator and vessels. This is a multiple spring externally mounted, reverse balanced seal with O-ring as secondary sealing member. Various elastomers can be offered for wide service application. These seals are basically used on top entry agitators as dry running seals. When food products or pharmaceutical products are agitated in agitator, mixing of any other liquid will contaminate the product and affect its quality, hence these dry running seals are used. These seals don't require any external media for lubricating the faces, that is why they are known as dry running seals.
