Help. How do I remove this well pump from impeller.

Brother in law bought a house and this pump is dead. I'm going to get it repaired- but I can't seem to pull it off. 
tips? 
 

I wonder if there's a set screw holding the impeller to the pump shaft, which would unfortunately mean pulling a pipe off to see.

Obviously, cut the pipes.   Then replumb when pump is repaired.  For a few bucks more previous plumber could have installed unions to make job simple...

And correct that misstep by adding the unions during your re install

Yeah. That's the right way to do this. He's not super handy so I'll do it right for him.

Probably too late. 

I think you have to just "break" the seal on that thin round adaptor from the pump itself. Its keeping the impeller trapped. 

Get a flat head screwdriver and pry slightly to see if it comes off. 

The setscrew holding the impeller is usually on the end of the shaft. 

I am talking about splitting #3 from #9 here:
 

Ahhh- I was trying to remove 1 from 3. They're up on Port St. Lucie- might have to try I and get up there this week and do that. 
Today i taught him/helped him lay wood plank flooring. Tons of fun. Haha 

They are really cheap to buy new. 

If there's a Tractor Supply near you, these things should be around $300

You're probably better off to just replace the whole pump.

Looks like you remove capscrews #13 to separate the halves. Might be able to remove #11 and insert something to bang on the shaft to knock it loose.  Then apply power to the motor and see if it spins. Maybe it's just seized and you can unseize it.  If the motor works and sounds OK, inspect, clean, lube, and slam 'er back together.

I'd spend no more than an hour on this before following ShawnG's advice.

Also, I've never seen an above ground well pump.  How do you prime it? How much suction (in feet) does it have to pull? Is the pump rated for that (not being overworked)?

That's a shallow well pump, works to about 30' down.

Replace it, then tinker with the old one and see if you can get it working. If you can, stuff it in the shed as a backup for when that one fails.

I'm jealous, my pump is a few hundred feet down on the end of a pipe.

No idea on your final questions- but this is south Florida and it's just for irrigation and not consumption.
