I have a pair of Topline C100 pumps that worked FLAWLESSLY for about 8 months or so.
Now, I can't get them to seal reliably. I seem to be pulling them apart and cleaning every other week. I've replaced the carbon seals on both pumps within a couple months of putting fresh seals into them.
Something must have changed in my process that makes me burn through seals so often.
I have noticed that the plate that the carbon seal presses against has become worn over time. There are circular grooves worn into the back plate where the carbon seal sits. I tried taking some fine-grit sandpaper to smooth it out a bit and it seemed to take care of the leak (after replacing the seals), but the problem keeps coming back.
Any ideas on how to get these pumps back up and running like new and not burn through seals every other month?
Could the springs be wearing out and putting less pressure on the carbon seal?
