Does anyone have a supplier for back plates for some old school Thomsen pumps? I have two very abused pumps, I believe #4s, and the seat for one of the rear seals is worn clear through and the other is barely holding on. The pumps are 1.5 and .5 HP. Sorry I don't have the model numbers, I sandblasted the collars earlier and left them at my shop. They both start with 4 though.
Attached you can see the daylight through my backplate. BTW, I didn't do this, it came as part of a lot of equipment and this is what I found when I took it apart.
Any help is appreciated.
Did you try Thomsen directly? I've bought seal kits and backplates from them directly before.
That has to be the most worn out backplate I've ever seen!
If you need Thomsen pump parts I had great luck recently working with them direct. We ordered a new back plate and it shipped out the next day.
