LPA 90B
API 682 4th Edition Compliant Pusher Type Dual Back-to-Back Mechanical Seal
LPA 90B
LPA 90B is a pusher-type mechanical seal engineered to meet API 682 4th Edition standards. Designed for high-pressure applications, this seal features a Back-to-Back dual-seal configuration, ensuring higher pressure containment and enhanced leakage control. The Back-to-Back arrangement provides a pressurized barrier fluid system, making it ideal for handling hazardous, toxic, and volatile fluids while maintaining low emissions below 150 ppm. Built for an extended service life exceeding 25,000 hours, LPA 90B enhances equipment reliability, operational efficiency, and environmental safety. Its reverse pressure capability makes it a preferred choice for refineries, petrochemical plants, and oil & gas applications where stringent leakage control is required.
