Mechanical Seal Knowledge Center

Learning how to measure a mechanical seal accurately means recording more than one diameter. A

A mechanical seal leaking after installation usually indicates an installation error, damaged sealing surface, incorrect

Choose mechanical seal face, elastomer and metal materials according to the actual fluid, temperature, pressure, solids and pump operating conditions.

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

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.
