  • Single Phase / Pump Recommendations??

    Hi Everyone,

    We are putting together a 7 BBL brew system.

    However, We only have single phase electric, could anyone recommend a single phase sanitary pump ideal for transferring wort, cleaning, etc?

    Thanks much,

    If you get the right VFD to control the speed of the pump, you can use a single phase wall outlet with a 3-phase pump. At least that's what I can do in Europe with standard 230v single phase... in the US I'm not sure how that works with 115v. A vendor like CPE would be able to help you though.

    Edit: looking at the first couple data sheets here, it looks like at least some of these VFDs accept 115v as an input, with 3-phase output to control the pump. You might be limited on the power of the pump with single phase 115v though, but at least their 2HP VFD works with 115 which should be more than enough pump for 7 bbl. We have two 1.5HP Topline pumps with our 7bbl system.

    Our KBDA Digital Drive - NEMA 4X / IP 65 VFDs provide variable speed for 3ph AC Induction motors from 1/8 through 5 horsepower.

      I second the recommendation of getting a 3 phase pump with VFD. You can get 208v single phase, run it through the VFD and instead of having to throtle your pump with a valve, you just dial in the frequency. Plus, as you grow, everything will become 3 phase, and you wont have to worry about buying a new pump then. 2 hp pump is 7.4A for a 3 phase 208v, thats 2.66 KVA, on your single phase line that would be about 13 amps, so you could run it on a 20A circuit. The guys at CPE probably could give you some recommendations on pump HP and sizing for your brewhouse.

        C-114

        We use Waukesha C-114 for CIP duty and they can be patched in in a pinch just about any location on the 15 BBL system.
        Its typically a 1 HP, 115V motor setup. There are some other exerts on the forum that may be able to advise you on how much pump you need for your design.

          The C-114 pumps are one of my favorites--mostly because I'm the one fixing them. It's about 5 minutes to change out a shaft and casing seal on one, compared to up to an hour on our other pumps.

          But I would also strongly advise getting it with the 3-phase 208/230V motor and a single-phase-to-three phase VFD. Being able to simply dial in the speed is a great advantage, especially when vorlauffing or transferring to the kettle.

            Thanks much for the great input. I was worried we had to install 3 phase before we could open. So for a 7bbl system it sounds like I should be able to get enough power to drive the pump with a 20amp circuit. That would be good. I'll start looking for a vendor today. Cheers

              Your other option might be a rotory 3 phase converter. I had good luck with on e of them in my last brewery.

                I would think about getting 3 phase service if you don't already have it, as things get bigger on single phase, the amps go up pretty quickly. 12 ga wire is much cheaper than 10, or even 8 ga wire. Plus everything is more efficient at 3 phase. The big headaches will be your chiller and cold rooms, you can only get up to certain sizes single phase, then you need 3 phase.
