SUBJECT: A quick reference to prevent potential seal and pump problems. 8-6

The biggest advantage of experience is you have hopefully learned what can get you into trouble. The following information has been explained in detail in previous technical papers, but I still see the same problems re-occurring on a daily basis.

Take a few minutes and look at the following. It might save you a seal or pump failure.

THE MECHANICAL SEAL

MATERIALS

APPLICATION

Remember that chemical attack can be accelerated by temperature, fluid concentration, and stress. Past plant experience is your best indicator of what seal and pump materials to use.

CONVERTING FROM PACKING TO SEALS

Horizontally split pumps:

Flyte sewage pumps can be converted to a single mechanical seal if a special adapter is made. It's worth the problem. You only have to seal the bearing cavity in this application

MISCELLANEOUS

CENTRIFUGAL PUMPS
