Knowledge

Understand how overheating, dry running, thermal shock and poor lubrication damage mechanical seal faces, elastomers and surrounding components.

Compare carbon, ceramic, silicon carbide and tungsten carbide mechanical seal faces and understand where each material is most suitable.

Follow practical mechanical seal installation, startup and maintenance principles to reduce face damage, incorrect setting, dry running and premature leakage.

A Flygt 3153.181 mechanical seal replacement should begin with the exact pump configuration, not only the number “3153.181.” Pumps can

Understand how mechanical seal faces, secondary seals, springs and the fluid film work together to control leakage around a rotating shaft.

Learn how to select a mechanical seal by checking pump information, fluid, pressure, temperature, speed, seal design, face materials and elastomers.

Understand mechanical seal support systems, including flushing, cooling, buffer and barrier arrangements, and when each function may be required.

Identify common mechanical seal failure causes, symptoms and troubleshooting clues involving dry running, vibration, contamination, heat, installation and operating conditions.
