I sent you a message a few weeks back with a couple of photos of a fragrance machine that I've had sitting around for awhile and would be willing to sell. I never received a response, so just checking to make sure you received the message. No big deal if you are not interested.
These pulsatron pumps you have are originated from the Belanger (with wire connector)? Do you have 2 different model? I have the a big one for the presoak and smaller one for triple foam. How old are they?
Oh btw, do you have any injection check valve laying around that I can have?
Side question, any chance you have the proximity (sensor at treadle)?
