I have used only two different type of low pressures pumps for the past 25 years. Flojets and Goulds shallow well pumps. Currently the Goulds pumps are for foam brush only, and the flojets pre soak tire cleaner tri foam. I would like to start using the procon pumps for tire cleaner and pre soak as the flojets don't seem to hold up very well to the chemicals. Currently using Viton in the flojets. The old Gould pumps are fine for the foam brush as no harsh chemicals, but I would like all the pumps to be the same. How do setup a procon pump system? Do I need a bladder holding tank as with the Gould pump? Is the procon driven by air or electric? If I did switch to procon, would I get more than 6 10 months before a rebuild as I do now with the flojets? Mike
