Cheap compact wort pump

[wbarber69]

I also just bought 4 of these for $30 shipped. Shipping is really fast, paid this morning and they will be here in two days.

Have they shown up yet, and do they have threaded inputs and outputs?

 

[Sourz4life]

Been reading through this thread and great stuff. Now I have never messed with electrical before, although though this seems much more simple. First off, what is the best PWM to use on this, affordable wise. Is http://www.ebay.com/itm/13114715278...&ssPageName=STRK:MEBIDX:IT&afsrc=1&rmvSB=true a good solution for that. Also does anyone have a link to either ebay or amazon with the correct power supply I should use. I've never done any wiring but I'm assuming this is more plug and play where I just twist the wires up and put one of those rubber coatings over the spot where I do so. Sorry may be a newb question but I've never done anything electrical.

The most recently posted eBay link shows photos that beg to differ. which is why I made my comment in the first place

The most recent link was from someone who found the pumps with barbed input/output selling for much cheaper than the threaded versions - so the 1/2 bsp is close enough to 1/2 npt comment makes perfect sense

These have nipple fittings on the motor. But this is not the same motor as the original forum post though.

Did you get 12v or 24v motors?

My 2 cents: I bought the original ops pump and for the most part it works great. However, on high gravity batches, the thickness of the sugars seem to gum up the mag drive about 45 minutes into the mash, causing it to stop working, often times requiring dis-assembly to get cleaned and started again. Otherwise, it works great. FYI, I only use it for 70-155 degree re-circulation before and during the mash, and nothing else.

Aren't they? My FPT quick disconnects screwed right on:

By the way, you inspired me to build my own box around this pump, it's been awesome for 3 batches so far!

Have you had issues with getting it primed? I had a heck of a time yesterday to get it primed.

Cool!

It looks good and I like those disconnects!

The way mine is set up priming is never an issue. Once I open the valve it's already primed even before I plug it in.

I don't think I ever got an answer here but what is the best suggested power supply for the http://www.ebay.com/itm/231681884498...:MEBIDX:IT pump. Have little knowledge of these types of electronics although I'm sure its basic.

 

[ajw85]

For my 2 24V pumps, I'm using an 18V 4A laptop power supply.

I then have one of these on my pump box:

and then wires running to my PWM controllers



This would suffice. And get a power jack and then do some soldering.

Does it run well with the laptop suply? I supose the flow it's a little slower?

 

[scaesare]

I found a 24V 2.3A power supply (similar to a laptop supply) in a junk cabinet at work. I also used a barrel connector in the pump enclosure.

 

[ajw85]

Does it run well with the laptop suply? I supose the flow it's a little slower?

Yeah they flow great. @ 18V. Even with the PWM controllers, flow is faster than I'd really like it to be for vorlaufing. Another annoyance is that I have to turn the PWM controllers up to 50% to get the pumps moving but then after that, I can dial them down to the speed I.

Sending it through the wort chiller is awesome though.
I just bought a bunch of camlocks and my 'dream' is zero drops spilled and a completely clean floor from mash in to the fermenter.

 

[rack04]

Will this power supply work for the 24v DC version of the pump?

I purchased one for a similar pump, have not tried it yet though, should.

https://www.amazon.com/gp/product/B00J8CG86G/?tag=skimlinks_replacement-20

Probably. The pump I have is rated to pull ~800mA @ 24VDC, so that 1A should be sufficient... although it never hurts to have a bit more headroom on the supply side... especially with the cheaper supplies that may be rated "optimistically".

 

[augiedoggy]

They do work better with a 2amp supply vs 1 amp I have done a decent amount of experimenting with different power sources and went from a bigger one to a 1 amp temporarily.. I noticed it took a higher setting on the pwm to get it going and they were more likely to stall if anything got in the flow path.. less Amps just means less torque in this case I guess.
I have both the 12v and 24 and this is the case for both.. I now power 3 24v pumps off of one main supply in my control panel which I believe is 6 Amps from memory.

24v pump supply yay/nay?:

@augiedoggy, you've mentioned a 6amp supply a few times, how much did that cost you?

That's a fine power supply but for the same price or a few dollars more you can step up to a 10 amp. You might as well. The only down side is a larger footprint in your pump box or power distribution box.

Nice find, thank you. I guess I wasn't searching the right keywords.

I assume this is switching and adjustable?

 

[KurfBrew]

Would this be an acceptable pump?

5M/16.4FT Head 24V 100°C Hot Water Solar Circulation Pump Food Grade Silent


Earlier in the thread I saw some concern over whether or not the black ones had sealed magnets or not and that potentially being unsanitary. What spec am I looking for to tell if a pump is fully sealed or not?

 

[augiedoggy]

The tan ones are food grade ppsplastic with sealed encapsulated magnets The black ones that I've seen are not. Someone would need to buy this and pull it apart to varify but it likely isn't truly food grade or designed for it but rather water recirculation for solar water heating. Chances are it's also made of and plastic which might or might not be stable at boiling temps.. most abs is no longer food grade beyond 170 degrees... will you notice off flavors or feel sick ? Not likely and this seems to equate to good enough for many folks here so..

 

[jwm1485]

Anyone know a good place to buy one of these pumps now?

 

[thekraken]

I bought a couple of these, got them in the mail last week and haven't been able to test them yet. *cough* Don't forget your power supply.

I have 2 more of these on the way as spare/back-up pumps. The 2 have been using have been trouble free so far though.

What are you guys using for a power source?
