My 11 year old 2 HP Whisperflo (WF-28C) motor is shot. I took it to a motor shop and they said there was only 2 things that could be done for it. Replace the bearings, and replace the capacitor start. Other than that, they said there was nothing else they could do. I think, more accurately, they meant those were the only 2 things it makes sense to do. I told them it was throwing sparks and tripping the breaker. Based on this they are basically telling me the windings are shot and it is not worth rebuilding? I think that is right. There was a leak starting at the shaft seal, and I had to tear it all apart to get just the motor to them in the first place. So... I'm thinking by the time I buy a new motor and a seal kit and impeller (old impeller is looking eroded at the leading edges), I would be best served by buying a whole new pump.
1. Does this thinking sound right?
2. WF-28C: What does the C mean? I'm not finding that designation on any of the new pumps available.
3. I'm leaning towards a new single speed as close to the old one as possible. Is that a WF-28?
4. Would I be better served by something else? One of the pumps with an EE (Energy Efficient) rating, one with a better Service Factor?
I'd like to save money on electricity, but by the time you get into the 2 speeds or VF's or VS's, then I have to add additional cost controls not to mention the more expensive pumps.
I'm not into any additional complexity. I like cheap & simple. I love my Intermatic mechanical timers. Easy to set and as bullet proof as it gets. I've heard, or read, of others who have gone the high dollar controller/pump route and been shelling out dollars ever since for replacement boards and new motors.
