I wouldn’t use a
Flo-jet pump on Tire Cleaner, Engine Cleaner or Presoak. We use a Procon pump on all the caustic chemicals. I’ve got a couple of Procon pumps that have been in service over 15 years, never been touched. The only place we use a
Flo-jet is on the Foam brush system. We don’t have any driers or moisture separators on our air systems, never been an issue. It can’t get much more humid than here in Western Washington, it's wet here almost all the time.
