Cheap pump and FDA approved 12v 100c

[SpottedDogBrewing]

Got my pumps today. Here's a picture of both of them. I'll try to get them setup today and see if I can shoot a video of them doing their thing.

could you post a pic of your power supply or cord for the larger pump

 

[EllisTX]

Just ordered one. I plan to use it for recirc the mash and whirlpool.

 

[rmaloney86]

I'm confused as to where the video is, maybe I'm having browser issues?

 

[detlion1643]

I can't see the videos either, using chrome on win7 here...

It seems as if these pumps are doing well. Is there enough of a draw to run through a whole house filter or 2? I'm keeping an eye out for ways to filter the yeast and get a more clear end product.

 

[Ramitt]

Hmm, thanks for the info

 

[rmaloney86]

So whats the concensus? Could the 12v pump recirculate my mash?

I always get some grain particles that make it through my false bottom, go through my march pump, and get stuck in the sparge arm. I use this little 12V pump to recirc in my HERMS. The impeller and impeller housing is pretty small...definitely small enough to trap a particle. But....could be worth a try. It would really suck if it ate something though.

Don't have pictures, but an old computer's power supply will run a few of the 12V pumps without a problem.

I don't have a filter setup, so I can't comment on that.

I use a stainless braid and don't have a problem with particles going through, but I'd think that the occasional particle would not be a problem, but a few of them going through may be a different scenario.

Have you experience with this pump?

Yes, I use the 12v ones.

How are you using yours?

 

[mendesm]

Single tier setup with 10 gallon cooler and 2 of these SS pots.

My setup is not permanently mounted yet so I just secure the hoses connected to the output of the pumps up and over the sides of the pot/cooler's side. The pumps are placed horizontally, just under the pot/cooler, with their outputs facing up to let any air bubbles to freely float out of the pumps.

I don't recall how high the cooler is, but it's definitely way under 3 feet high, probably closer to 2. The ss pots are only 17" high.

For the pump between the cooler and the kettle, I just move the output hose to recirculate/transfer accordingly.

With either pump, just open the valve, let gravity prime the pump and turn it on.

EDIT: I do have 2 of the 6v pumps too. I'll end up using one of those just for recirculating when I get around to finding a final and permanent place for my setup. Eventually the whole thing will be a computer controlled electric setup.

EDIT 2: I did purchase a march pump before I bought the tiny ones but never got around to using it. As it is, I'm probably going to end up putting the march pump for sale.

 

[rmaloney86]

I bought one to try it out... I'm 90% through making a Direct fire temperature controled BIAB system (Just need to paint the stand) I just need it to recirculate the warmer water from the bottom.

These look awesome! You have links for the youtube videos you posted earlier in this thread? they dont seem to be showing up for me today

Interesting, I can't see the video links in my previous posts either. Here they are again:

 

[EllisTX]

For the electronically disabled, could someone throw out some good permanent options for powering the pumps?

 

[mendesm]

For the 12v ones, any 12v power supply that can put out 1A (ampere) will work. For the 6v pump, pretty much any cell phone charger should work.

Thanks. I've got a 12v that puts out 300mah. Will that harm the pump or just not let it work at it's full capacity?

300mA will not harm the pump, but it will not be enough to make it work. Likely scenario, your 300mA power supply will overheat, spew some smoke, maybe spark and crackle a bit, and go poof; worse case scenario you'll have a power supply on fire to put out.

This pump is rated at 12 watts. Since we know it operates at 12v, we can use POWER (in watts) = VOLTS * AMPS and work it around to POWER / VOLTS = AMPS and we have:

12w/12v = 1a

So your power supply must provide 12v (it's safe to say +/- 0.5 volts) and be able to handle 1.0 or more amperes.

Rules of thumb when working with electricity:
1) always match the voltage between source and load (leave the +/- X volts for the pros)
2) Power supply provides amperes >= load consumes amperes, which translates to:
2.1) Power supply rated at equal to, but preferably more, amps than load consumes
2.2) Load consumes equal to, but preferably less, amps than power supply provides

Awesome. Thanks for the help. I'll keep searching around the house and hit up eBay if I can't find one.

If you don't find one, any store like Radio Shack will have something suitable.

any clue how these things handle recirculation of cold liquids? I really wanna set up a glycol system for my fermenters. Trying to figure out a way to mount a coil into a keggle turned into a fermentation vessel because I want to step up to a 10 gallon batch but my freezer can only fit one sanke (I want to have the capability to have ales and lagers at the same time as well)

 

[detlion1643]

Have you used this from a racking cane/siphon before, or only from the spigots/outlets on your containers? Being non self primed, you can just let the liquid flow into the pump then turn it on correct? I'd be putting it inline from carboy -> pump -> filter -> bottling bucket.

I asked about the power to draw through filters earlier, but I might pick up 1 of the cheaper 12v ones and report back. Not like it will break the bank to test it... If I do, what connectors/adapters will I need and what tubing?

Cool liquids are fine, I've used it to recirculate near freezing water, but I can't speak for below freezing temperatures.

Yes, I've used it with a racking cane to transfer some beer from a carboy. You're correct that it won't self prime. I just used a carboy cap and blew into it to get the beer to go up the cane and into the pump before turning it on and it worked like a champ.

I really don't know about the filter. I don't have a filter system to do that test. The pump is rated for a 3 feet rise only, without any flow restrictions. I'm sure that if you put a filter on the line it'll restrict the flow and it will affect the pumps ability to push liquids up. You'll likely have to place the bottling bucket below the carboy/filter.

For the 12v pump I use 1/2" ID hose for the inlet and 5/16" ID for the outlet and a couple of ss hose clamps to secure the tubing to the pump.

 

[thelorax121]

Yea, don't see this working too well for a filter. Whenever I filter, I push with CO2 and the psi required to get the beer through all that tubing and the filter medium (especially as it gets clogged) is probably out of the range of this pump.

Also, diaphragm pumps like shurflo are a better bet for cold side transfers because they operate at 30-45 psi, and they don't aerate the beer nearly as much. Centrifugal pumps like this one operate via an impeller spinning at a constant rate (for a given voltage), and the flow is regulated by opening/closing the outlet. Therefore, if you are transferring green beer at a slow rate with one of these pumps, the beer inside the housing is being whipped pretty brutally while it waits to be pushed through the outlet. By comparison, diaphragm pumps use rollers which are much gentler, and they self prime.

 

[Thundercougarfalconbird]

Interesting. I've never seen a centrifugal pump like that. Is it possible to use with carboy fermenters or is the vacuum too strong? (About to use co2 to push beer from carboys I think)

I'm not sure I understand the question.

I have used it to transfer from bucket (primary) to carboys (secondary) and then from carboy to keg, if that's what you're asking.
