i'm thinking of getting 2 x new pumps to replace the one i have can i get some links and recommendations to what pumps work well for brewing on the dark-side
you need a Power controller . . . Not on my PC at the moment, but have a link to one . . . The pumps get a bit unstable below 50% Speed though as I have two RG550's like yours, controlled with a couple of Phase Angle Controllers Warning Again Not Cheap. Unfortunately UA have stopped doing the 6A one I use for mine.
Another way to control the RG550s without using motor control is to put a bypass loop between the in and out ports with a valve on it. This one is mine
You can run the RG55 at full pelt and with the bypass valve open very little gets sent out of the 'out' port
FWIW, the March 809 for the price is impossible to beat as it will happily pump boiling liquids all day. Also, they've just 'uprated' (I use the term loosley) it for Morebeer in the states, see here so maybe worth asking about the new pumps.
If you're only likely to be pumping liquids to 80 deg c ish then the Totton GPO 20/12 is another stalwart of a hb pump. Norm of corny fame can supply these, here for around £60. The only 'downside' is that they don't like restricting too much :thumb:
Also worth a good look on E-bay for the March 809's from the US, still cheaper than the U.K ie, here
thankyou very much, I have started playing around with what i have already. and I am about to go inside a restaurant dish washer to have a look at the pump inside. basically im trying not to part with cash.
