Which Wort Pump to chose?

[DerekDH]

Hey all, I'm working on building my counterflow chiller and was just wondering if you have suggestions on which pump I should get. It needs to be strong enough to pump from my kettle (I have about 4' hose) to and through my chiller (2' hose followed by 20' of 1/2" copper pipe and a bit more hose at the output). So far I'm thinking one of these two:

but if you have suggestions that are better (bear in mind I'm trying to stay around 50-100$) I'm welcome to those. Thanks!

note: don't worry, I won't be using that drill pump, that was most definitely a mistake, I mean learning experience - now I have to clean oily lube out of my chiller - experience is the best teacher.

Well chugged or March are the main ones people are using. There is also a thread on here "cheap compact wort pump" which seem to work well also despite their size. There is a guy selling them bulk in eBay. I just searched brushless 24v pump and it was the first listing to show. If your trying to keep it cheap I think he was selling for 6$ a unit buy will negotiate as others in the "cheap compact wort pump" have gotten different deals when discussing options with the seller. Either way you wind up going would be better than the drill driven pump.

thoughts on this? http://www.ebay.com/itm/12V-Solar-H...463497?hash=item58b5b1ffc9:g:vnAAAOSwq7JUIoLW I don't really wanna wait 2 weeks for shipping from China though... but if time wasn't a concern, probably a good secondary to have.

A lot of these pumps are DC, so is there an easy way to convert them to wall plug ins? Do I need to build/buy a rectifier or a rechargeable battery? Just not sure how to go about doing that, electronics and circuitry was my least favorite part of physics.

That pump look pretty similar to mine. Aside mine has barbs not threads. As for powering I'm looking for a multi-volt adapter to use with mine. Also thought of using the DC transformer from a model train set which would allow variable speed on the pump. Most cell phone chargers and such also output DC current although most are usually only 5-6volts which would only operate your 12v pump at half speed at best.

Think something like this would work if I stripped and hard wired it to the pump? the pump I linked is rated for .7 Amps and a lot of the other AC/DC converters are above that, but this one is 500mA or .5 Amp - so thats within the rating, and it has variable outputs 1-12V.

Yeah I think that would work fine.

That adapter will not work for that pump. You need an adapter/power supply that can put out more power than the pump needs, that one puts out less. That pump requires .7a so I would look for a power source that puts out 1 full amp so that you aren't pushing it.

Whichever power supply you get and I want to back up EW Jim's suggestion on ensuring it is more than less amps required by your pump. Instead or stripping the wires I suggest getting an appropriate female connector for the pump. That way you can use the power transformer for other things like fans or anything else that might need variable voltage.

 

[DerekDH]

so hard wiring one of these two?

Found a Philips ac/dc converter at the thrift shop for 99cents, it's 15V output @ 800mA, do you think the ectopic 3V and .1Amp would stress and burn out the motor or do you think it's fine?
