Hayward Max-flow vs pump replacement and upgrade

Hello,

I have a hayward max-flow vs pump that needs a motor.  Can I replace it with ECM27SQU?  If so, would i need to upgrade the impeller/diffuser to get the extra flow?

Thank you,

Albert

Hi Albert - it might work, but there were a few versions of that pump manufactured so we would want to be certain before recommending a replacement.  What horsepower is the motor that is currently on your MaxFlo VS?  Upload pictures of the motor label and the pump label (or the pump itself) if you are unsure.
