    Default Mechanical seal or packing gland

    I have done a search but haven't happened upon a discussion of old school vs modern technology. Which is better? I already have a brand new shaft and suction housing is on the workbench (freezer) awaiting warm weather for Installation.

    I use multiple seals but would not recommend it for a lake use boat kinda a race only thing and I replace the seals every season not worth the pain in the ass for a very small gain

    The various mechanical seal offerings work well with pump shafts in good condition with good finish in the packing seal area , bear in mind however that if replacement of the seals or seal pack becomes necessary the jet must come at least partially apart to repair/replace versus simple packing replacement , additionally the suction housing packing bore needs to be in good condition (not corroded or pitted )

    That is what I needed to know. If it was the next big thing I would have to have it. I think I'll stick with the packing. Thanks for edumacating me.
