Retrofit to Variable Speed

So I have a ~12k gallon inground pool and have been contemplating switching over to a variable speed pump for the energy savings. I currently have two Hayward SP2805X7 pumps (one for the non-heated spa and one for the main filtration pump). I already replaced one motor (filter motor died, put the spa pump motor on my filter pump while I waited for my new motor to come in) so the new motor is on my spa and rarely gets turned on. Is there a variable speed motor that is compatible with that pump I can order and if so what are my options? I’m assuming I can use any motor with a 56J flange from Hayward but don’t want to assume and be on the hook for the price of the motor.

We’d recommend model ECM16CU. The ECM16CU is a 56J frame variable speed motor. It will mount up to your existing Hayward Max-Flo pump.

We’d also recommend replacing the seals when you replace the motor. The seal kit is part number GOKIT1. Use GOKIT1SALT if you have salt water.
