Standard Dual Cartridge Seal
LP350
The Standard Dual Cartridge Seal is designed for secure sealing in pumps handling hazardous, volatile, or high-temperature fluids. Its dual cartridge arrangement provides an additional sealing barrier and supports effective barrier or buffer fluid circulation, improving leakage control and operational safety in demanding process environments. Since 2002, Lineproof Engineering, based in Mumbai, has been developing precision mechanical shaft seals and advanced cartridge sealing solutions engineered to meet the reliability and performance requirements of modern process industries.
