Leimbach pump tip

[SmallHaul]

Great info Rob!

I am working on a Wedico loader now that has a leimbach pump and a fluid soaked motor. I flushed the motor out with non-flamable CRC cleaner and that worked great but, after running it for an hour I could tell that a small amount of oil got into the motor again.

So, I will flip the motor over so that the oil can drain without going into the motor but, can I change the seals so that won't leak any more or won't that help?

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.
