    Anyone see a problem in using same pump in brewhouse and keg washing?

    It is open impeller mobile pump with VFD (1.5 kW, 5 m3/h, 24m) that is used for mashing in, sparging and transfer BK-HX-FV.
    I'd like to take advantage of mobility and give it another purpose with saving some funds, but I'm not sure if that could be problem due to hard chemical treatment in keg washing or something else... on the other hand we use same chemicals at MLT or BK CIP so I feel lost at the moment.. or I am over-complicating it?

    I'm no expert but I believe as long as the seals are rated for the chemicals, you should be ok. Ask the manufacturer if they're still around, but makes sense to me that it would work.

    If your speaking of the one in the pictures of this thread, I am hoping to use mine for whirlpool and CIP/kegwashing.

    I found that I needed to upgrade the inlet hose to 1.5" ID brewery grade hose otherwise I got cavitation pretty bad with the 1" ID continental hose.
    I tore mine down to the basic components and made sure I could get replacements parts for everything which I found cheap on ebay (A UL listed frame motor would cost me a couple hundred bucks if I ever had to replace it and thats by far the most costly component)
    everything in the pump housing is stainless or EDPM rubber except the ceramic or carbon pump seal (either are available for like $4)

    I was looking at the Velocio for a keg washer but i dont have the time to sit down and program it myself. Would you be willing to sell a copy of your script with a bit of documentation on your cabinet, PLC and the HMI?

    Any feed back on these pumps?

    No from me. Mine is still in the box. Maybe augiedoggy can give some feedback.

    Thought I'd post an update. The Keg washer works great but I wanted to share a 3D model of the cart I plan to weld for it.
