Installation, Operation, & Maintenance Guide

Style 78HT

Use thread sealant instead of thread tape. Thread tape has been known to break apart and
enter the buffer/barrier fluid stream, resulting in damage to and premature failure of the
mechanical seal.

Ensure that all tubing/piping is free of pipe strain, which can adversely affect the seal.

2

. Flood the seal support system with the recommended buffer/barrier fluid and ensure all air is properly

vented from the seal.

3

. Check for seal leakage.
