I need to rebuild or replace this motor, which sounds to me as though its bearings are shot. It's 3-4 years old and I'd like to replace it with a more efficient unit. I've read a bunch of the threads here about efficient pumps and 2-spd vs. variable speed motors and was leaning towards the B2981 b/c I'm wired for 115V.
I'm surprised that the B2981 specs 12.4A at high speed while my single speed pump "only" pulls 9.8A. I assume I'll need the high speed to run the navigator and to at least prime the 1-story rooftop solar heater. The pool is free-range (no screen cage) and I do get a lot of leaves/oak squigglies so I'll likely need the navigator running at least a couple hours a day.
Is the B2981 a good choice for this setup? Is the low speed sufficient for the solar array (once primed on high speed)? Am I going to realize any overall savings with the increase in power consumption at high speed? Or should I just replace the bearings in the pump I currently have?
