      I need a new impeller for my ES 2500 Evolution pump

      Does anyone know where I can gt one? We ordered one from Waterway (the mfg) but they sent the wrong one. If I could get a part number it would be helpful but we couldn't find one on the old impeller and Advantage has never gotten back to me on it. My son is resuilding the pump for me. We have everything we need except for the impeller.
      Thanks!!

      The manufacturers' part number for the impeller is 310-4000 . The shaft seal kit is PS-1000 .

      The link for the ES series parts diagram is https://www.advantageman.com/product...dpumpparts.htm .

      I've had success picking up parts on Amazon.

      Thanks! We thought it was 310-4210. Much appreciated! I talked to Advantage and they don't have the parts and couldn't tell me where to get them. We have the seal kit but not the impeller. I looked on amazon but I had ordered the correct one - they sent me the wrong one although the one pictured in the listing was like what I'm replacing. So annoying.

      Talked to a person I have dealt with before at Advantage and he sent me what I needed. My son rebuilt it all for me and now it's running beautifully!

      I have heard that story so many times.

      Employees promoted way way beyond their capabilities.

      So frustrating,if only.

      Started up my ES4500 a couple days ago and the seal was leaking. Ordered a replacement thanks to this thread, but I cannot get the impeller off to replace it. I just can't get any kind of grip on the impeller wheel because the housing comes up around it. I removed the whole rotating assembly so I can grip the other end fine.

      Curious to where you found this part number? The manufacture part list linked doesn't have this part number or a ES2500 pump impeller listed.

      Remove the fan cover, fan blade and unscrew the 4 long bolts which bolt the stator or

      electrical winding assembly to the front pump body off,carefully slide the windings off the

      rotor.

      The rotor can be held in a vice firmly, to allow your next step which is to loosen and

      remove the impeller and allow you to gain access to the leaking water seal.

      Check and replace the ball race motor bearings as a precaution before reassembling the

      pump.

      Fit only the very best bearings available.

      I have it in a vise but still can't get the impeller to budge. Just can't get a grip on it. Tried a couple different size strap wrenches and an oil filter wrench. I think I'm going to sacrifice the impeller wheel and drill a couple screws into it to hold a breaker bar. This pump is going on ten years old and the whole shaft is very rusty. I figure the $30 impeller is worth trying before I give up and drop $500+ on a whole new pump.

      Could it be a left hand thread?

      Is it possible to get penetrating fluid on the shaft to run into the threads.

      Shaft now vertical,impeller catching down, catching the penetrating fluid.

      Alternatively withe the rotor firmly held in the vice,could you try locking the back of the

      impeller on the the pump housing and turning the housing left or right on the back of the

      impeller?

      Could the impeller take a direct flame on the center where the shaft thread is, to heat it

      up?

      The impeller threads would then expand on the shaft threads?

      Mine isn't quite this bad, but this video shows a crusty old motor rebuild. https://youtu.be/tT5aQzCE5GM?t=756
      Video is of a Waterway Spa pump, which from what I can tell the Evolution ES4500 shares parts with and looks almost identical. The electronics are different.

      He does mention in the video having to potentially destroy the impeller to expose the nut holding it on. I'm not to that point yet but we'll see where today takes me. :D

      No patience can cost a lot of money.

      Immerse in a paraffin or turps mix with some oil to try and break the bond.

      Is it a metal or plastic impeller?

      When in doubt use a hammer,the bigger the doubt the bigger the hammer!

      Lol coolwon, you go from saying be careful to get a bigger hammer in the same post.
      I ended up going surgical amputation on it. Turns out the neck that extends out the back of the impeller through the seal was completely disintegrated. I had to cut the plastic impeller out from around the brass nut then use a ~2ft breaker bar to free it. It had been soaked with WD-40 for 2 days.
      If $40 in parts gets me one more season out of this pump, I'll be happy with that.

      I didn't mean to hijack this thread, but who knows, maybe it will help someone else fix their pump instead of replacing.

      You got your colors for persevering,more important giving feedback,

      Ask for assistance,feedback helps everybody.

      Will they learn!

      Stay away from water pumps with steel shafts!

      Stain steel used to be expensive.

      Now its an everyday occurrence.

      WD40 and others good for rusted nuts and bolts. For calcium and rust use a product that removes mineral build up and rust. Give it time to dissolve and work on the buildup and rust and then rinse and use a penetrating lubricant.

      CLR calcium, lime and rust remover spray.

      WD 40.

      They have a habit of short changing with the drive propellant.

      Just one more squirt!

      Shake the can,what do you hear?

      WD40 liquid.

      I have can of emptiness above the portion of liquid WD4O, swishing around in the bottom.

      More than once,and I find 3 x the price this side of the equator.
