ITT Goulds” Taper Bore Plus seal chamber is designed to allow the mechanical seal to run cooler and with better face lubrication. It”s also configured to keep solids, air, and vapors away from the seal faces to extend seal life. The Taper Bore Plus is an enlarged seal chamber, which allows increased radial clearance between the mechanical seal and the chamber, providing better liquid circulation thereby improving heat removal. The Taper Bore Plus also has a Vane Particle Ejector, which directs solids away from the seal faces. The design also supports the efficient removal of air and vapors.
