  • DIY VFD pump

    Has anyone made their own VFD pump using a pool pump variabe frequenct drive inverter?

    Many pool pumps are not 3 phase, which you need to have for a VFD drive. Secondly, and probably most importantly, do not use a pool pump for beer, it is not sanitary or food grade, and will likely cause you more problems and cost(bad beer) than just getting the right pump to start with.

      I think he's talking about the VFD, not the pump.

      If the VFD can handle your pump--most VFDs are rated by horsepower--then it's just another VFD. You'll likely need to put it in a wash-down rated housing, and be sure it has enough cooling.

      VFDs are getting cheaper every day, so re-cycling one vs buying new might not make sense.

        NEW VFDs on clearance sale.

        Great timing

        We got a pallet load of VFDs from a local motor shop that just went out of business. They are a couple of years old but all brand new and still in the original boxes.

        We are passing along the savings a clearing them out.

        Please note the following:  We only offer a 90 day warranty on clearance items. There are no mill certificates for clearance items

          Yes, I'll be using a food grade stainless pump.
          As for the VFD, it will most likely be new since the prices are reasonable.
