Hello Trouble Free Pools,
I have a burned out Pentair Pinnacle 3/4 HP 1.27 SF pump with the following numbers on it:
The motor burned out in the last few weeks. It was making a lot of bearing noise last year and it finally gave up the ghost in the last week. So, instead of replacing the whole pump, I was just going to replace the motor. This is for a 12,000 gallon pool. Before I do, I have a few questions.
#1 - Is there a 2-speed motor that I can drop onto this pump for more efficiency? I'd really like a 1/2HP continuous with a 1.5HP or 2HP option for running the cleaner with some sort of switch to decide between them.
#2 - If there's no 2-speed motor option, what's the most efficient 1 speed motor I can drop into this pump without changing out the impeller? Would a 1/2 HP motor be sufficient? or would I need another 3/4 HP motor?
#3 - When replacing the motor, is there anything else I need besides the motor itself? Looks like it's just four bolts. I imagine I would undo the 4 bolts and pull the motor straight back from the pump. Do I need to replace anything else before dropping the new motor in?
I want to get this remedied today, if possible. Thanks for all the help!
