Mechanical Seals
Multi Spring Dual Seal
LP90D
The Multi Spring Dual Seal is designed for reliable sealing in pumps handling hazardous, high-pressure, and corrosive fluids. Its multi-spring design provides uniform face loading and improved heat dissipation, while the dual seal arrangement offers enhanced leakage protection and operational safety in demanding process environments. Since 2002, Lineproof Engineering, based in Mumbai, has been manufacturing precision mechanical shaft seals and advanced dual sealing solutions that enhance equipment reliability and process safety across diverse industrial applications.
