Topic tags/keywords: electrical motor water pump noob howmuchwoodcouldawoodchuckchuckifawoodchuckcouldchuckwood sell money

Hey guys, I recently picked up a 230 volt 3hp single phase water pump off the side of the road(a neighbor was throwing it away).
So I did what any reasonbale man would do and took it home and looked it up and i was surprised, the original system that it was a part of is over $500!
This leads me to believe it may be a useful item, or at least sell-able
So what do you guys think i should do with it?(p.s- it has no plug but is already wired, looks like the neighbor might have chopped it off?)
(p.p.s- if you look online,the water “turbo system” or whatever, the big silver thing on front, got taken off, i have no idea how!unfortunately i still have the stupid cast piece that is stuck on the shaft protruding form the motor, i want to take it off with out removing too much material)
Thank you ahead of time!

Why did they trash it to the side of the road? Have you tested it to see if it runs?

Cheers,
Brad

I unfortunately have no multi meter or anything of the sorts, i assumed they just threw away because it was old maybe?
I am going to order a plug for it, just need to find a cheap one.
But i opened er up, and she seemed good on the inside, no burning, no smells
thanks for replying so fast!

I have to believe the only reason a pump motor would be replaced is because it went blooey and possibly it’s just the start capacitor sitting on top. Did you hook a plug up to it? I don’t know what kind of duty cycle a pump motor has, but it’s 3450 rpm and 15 amps so it should have some oomph if it works and you want to repurpose it.

Typical point of failure on those are the bearings… particularly on a China made motor like that one. Most people don’t just trash a motor because it’s “old” :) My FIL has a pool service company, and they will swap the motors out rather than try to repair them – and then they just sell the old ones as scrap metal. Probably a good 90% of them only need new bearings or a capacitor.

Not sure if you could get much for it though if you tried to sell it… certainly isn’t an ideal motor for any type of woodworking machinery. It is a continuous duty motor (those things will run for 6-8 hours a day typically), but is non-reversible, has an odd ball sized frame/shaft, and it has an automatically resetting thermal overload, which presents a safety hazard.

Cheers,
Brad

I am about to go to work but as soon as I get a chance, I have an old extension cord that I might be able take the plug off of ( is standard 3 pronged enough? It medium to heavy duty)
But no I haven’t plugged it in or actually ran it
(Off the top of my head)-From just turning the shaft though, the bearings seem alright, not scratchy or rough but not like glass or anything
I’m excited bc I feel like this has some real potential!

It should be hot, neutral and ground. It IS 15 amps and may briefly draw a bit more on startup so you have to plug it into a 20 amp circuit. You need to remove or secure the impeller housing before you do all that.

Do you guys by chance have a suggestion of plug for this type of motor?
Ps. I have a garage shop with washer and dryer outlets, and my breaker panel says 100 amps max
By housing impeller do you mean that cast metal gray thing on front?

I’d get one that fits your 240v outlet – wouldn’t be very useful otherwise :)

Oh duh, I can’t believe I didn’t even think of that
Thank you for all the support guys, it’s really helpful for a beginner like myself

I missed that – thought it was 115. If you have an ELECTRIC dryer get the same plug type as that. But now you’re getting into money to find out it’s DOA without extra expense anyway.

Just looks like the pump shaft broke off. Probably sold as an assembly.

Yeah I have an electric dryer, I have to check the socket type
If it doesn’t start up will it be worth it? I don’t really have money to blow(college freshmen)

The NEMA frame, 56J, references the motor being for a jet pump and would likely require machining the shaft to be able to install a pulley with a cylindrical bore. It’s not enclosed so any application where dust intrusion would be likely could clog it up quickly depending on the volume and size of dust it was subject to. That it’s single phase could make it good for something, but not even knowing whether or not it works is a pretty big what if. Have you contacted your neighbor who threw it out to see what was wrong with it? That would be much faster and cheaper than sourcing a plug to find out if it works.

Thanks for the info!
I could contact him, but that might be really weird
Hmmm

If the motor does work well, I would most likely sell it or keep around a while until I need a motor for a stationary machine
Now that I think about it, I do have one of those outlet testers for construction, just lights up 140 or 240. Ya think that’ll be useful for testing continuity or something?
