Pool pump replacement

I have an American Products / Pentair Ultra Flow with a 1.5 HP single speed motor. The Volute cracked and I think it’s time to just go ahead and replace the entire pump and motor with the pump being almost 25 years old now. I would like a single speed motor which matches what I have now and would of course like to do as little replumbing as possible.

Which pumps can you reccommend?

We’d be glad to assist you. What is the service factor (SF) of the motor label? Do you have 1.5" or 2" plumbing?
