Metal Bellows Mechanical Seal

LP100

The Metal Bellows Mechanical Seal is designed for reliable sealing in pumps handling high-temperature and high-pressure applications. Its welded metal bellows construction eliminates the need for dynamic O-rings, providing consistent face loading and resistance to thermal expansion, making it ideal for demanding process conditions. Since 2002, Lineproof Engineering, based in Mumbai, has been developing precision mechanical shaft seals and advanced bellows sealing solutions that deliver durability, efficiency, and dependable performance across process industries.
