My PAS pump leaked a few drops each day. It was coming from the seal. I removed the pump (non-trivial and very messy) and replaced the seal with the two-lip part that is now being supplied. After buttoning everything up, it still leaks, about the same amount and from the same place. Pulled it again. The shaft is very clean, has a kind of matte finish in the area of the seal. There is a single shiny ring from the old seal and two much fainter rings from the new seal. None of the rings seem to indicate wear, they are just polished areas. Bearings are tight. No evidence of leaks from the couplings or the pump body. There was a lot of fluid around the ball bearing.
Other suggestions? Is a drop or three a day something that you just have to live with?
