Agitator seals of series NRA are factory assembled & dynamically tested units on steel, glass lined and Stainless Steel mixers, agitators & vessels.
This is a multi-spring externally mounted balanced seal with “O” ring as secondary sealing member. This seal can be used for corrosive services as the metallic components, i.e., retainer, spring and thrust ring do not come in contact with liquid to be sealed.
Dry running seals do not require any external media for lubricating the faces. Thus, these seals are used in food and pharmaceutical industries where external liquids might contaminate the product and affect its quality.
