Cheap Pump Wiring Question

[movet22]

So I have on order two of these style pumps:

I also have a sweet control panel from ebrewsupply that has 2 120v locking pump outlets, which I can only imaging are designed for use with march/chugger pumps. I am going to be using these for the foreseeable future in light of the bigger pumps and my question is: is there any way that I can wire these up to be able to be used with my panel's locking pump outlets?

I have seen this: http://www.amazon.com/dp/B006NTNGN0/?tag=skimlinks_replacement-20 which seems to handle the dc-to-ac conversion for a reasonable price, but I am pretty well lost from there

Thanks for all of your help, as I continue to show how poor my knowledge of this stuff actually is

I actually use a similar pump and power supply that you have listed. I just use a regular outlet on my panel.

I tried finding the locking outlets on ebrew supply but couldn't find them, can you post a picture?

I'm assuming you would have to somehow create an adapter that would allow the standard two prong AC/DC converter to connect to the locking plug.

I'm might be confused, but if I understand this correctly...

You have two 12v DC pumps with bare wire leads on them.

You have two receptacles on your control panel than you want to use for the pumps.

The receptacles are locking style. I am going to assume NEMA L5-15, like this:

120VAC, rated for 15A.

You need an DC power supply for the pumps. Actually one for each if you are going to do all of this externally. You posted a link to an adapter that you could use, and it has a weird little thing on the end that you could use to connect your pump leads to.

Which then leaves you with standard straight blade DC power supplies that need to plug into locking receptacles.

So, you need to find (or create) an adapter, like tyfernandez mentioned.

You'll can get a couple of these:

You can probably find those for cheaper than $20. I didn't search very hard.

Or build your own by getting a couple of these:

And a couple of these:

Those are probably also available for less than what I linked to, but bottom like is that locking plugs and receptacles tend to be a hell of a lot more expensive than straight blade items.

Your $20 pumps turn into $30 pumps with power supplies and then they turn into $50 pumps once you add adapters to make them compatible with your control panel.

Honestly, it will be WAY cheaper to take the locking receptacles out of your box and put in a standard receptacle instead, which will cost you like $3 total.

Just curious........Do you know what the threads are on that??? It does not say on the website. If its NPT, I would say you scored

Even if it's not 1/2", I'm sure a solution can be cobbled together to make it work.

It does look like a good deal. I would personally be more curious about whether "Food-grade: Yes" means the same thing in China as it does in the US.

I might pick one up, just to mess with it.

@Walker: I have locking plugs, they came with the panel that I bought from ebrewsupply. (I should have mentioned that I already have the expensive part.) My main question is if/how can I wire that dc pump into a 120v 15a locking plug. Sorry for the confusion.

@johns: the threads are 1/2'' bsp, but there is quite a bit of documented evidence that folks are making it work without any sort of issue in a 1/2'' NPT thread, provided enough teflon tape is used. My personal plan is to teflon tape the **** out of these threads and use SS quick disconnects to I am not screwing and unscrewing a bunch.

Here is the thread that I was referencing: https://www.homebrewtalk.com/f11/cheap-compact-wort-pump-375904/

Gotcha....

SO, you have locking plugs. That's good.

You just need some short lengths of extension cord with "normal" (straight blade) female ends on them then. Basically making your own versions of something like this:

Sorry for butting in, but you will need to wire that locking plug to your DC power supply, not the pump directly...

Right. That's what I said.

How did this work out for you?
