I’ve just had my Flotec pump model FPT20515 go out. I’m having a hard time figuring out what is a compatible replacement for it. Any advice?
Your best (and probably least expensive) option would be to replace the motor with this Century (A.O. Smith) 1.0 HP Full Rate Motor, Square Flange 48Y Frame, Dual Speed - Model SQS1102R motor (I believe your pump is two-speed; please let us know if that is incorrect). We recommend getting the Flo Tech, AquaTools, Dyna-Glas Pump Seal Kit - GOKIT44 so you can replace the seals and the motor shaft seal for a leak-free installation.
When you add in the service factor for that motor it will equal the 1.65 total horsepower that your current motor has.
