Mechanical Seals
Multi Spring Balanced Seal
LP20 & LP21
The Multi Spring Balanced Seal is engineered for reliable sealing in pumps operating under high pressure and demanding process conditions. Its multi-spring arrangement provides uniform face loading, while the balanced seal design reduces hydraulic forces on the seal faces, ensuring stable performance, lower wear, and longer service life. Established in 2002, Lineproof Engineering in Mumbai designs and supplies precision mechanical shaft seals and engineered sealing systems developed to enhance pump efficiency, operational stability, and process reliability across various industrial sectors.
