    Default Cleaning Diaphragm Pumps

    Curious as to what those of you using them, do to clean and maintain your diaphragm pumps. Run hot water through after each filtering, take apart ea year?
    I have a Wilden P1 that came with the Leader Clear Press. Aluminum body on the wet contact end. Any one using Stainless bodied?
    Thanks - John

    If I will be using it the next day or two, no cleaning, if longer, I run hot water (permeate) thru it, then run it dry a minutes or 2, then just shut down.
    Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
    Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
    Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
    After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.

    Thanks Dave. I’ve been doing that, but apparently not long, or often enough. Broke it down today and found it loaded with clumps of white crystal-like “stuff”. Going to boil all the aluminum fittings out and see if that cleans it out. It has no sugar taste to it, and is waxy.
    Not sure if it’s filter aide or what, but it it’s bugging me.

    I pumped hot steam hood condensate through mine after every use. I never took the pump apart to see what it looked like inside but never had a diaphragm or check ball failure after many years of use. I'm going to treat the pump on my new press, Wes Fab 7" full bank with Wilden AOD pump, the same way.

    I never looked at mine either except today,after splitting wood, I was looking for something to do. I was kind of surprised to see the build-up in there. Maybe it’s not an issue but it’s weird looking stuff and don’t think I want it on my pancakes.

    That weird looking stuff is before the filter so it would get filtered out. As hot as the syrup needs to be any bacteria or mold will get killed and filtered out if there's any in there.
