Re: Leimbach pump tip
I believe they use standard o rings as shaft seals. They are not particularly good and I have the same problem on my diy pumps. I changed to proper shaft seals and have not had a problem since. They will wear of course but are better designed for the job. I think the Leimbach has a small shaft 3mm? so finding seals for this size might be difficult. Lots of people also crank up the pressure and this is the result as well.
