Will this setup work with a 2 speed motor?

I'm trying to help out a family member that needs to replace their current pump motor. Their current setup looks to be using a 1 speed 2HP Pentair pump that filters a pool with about 25000 gallons capacity.

Can they simply buy a 2 speed 2HP motor and install it as a drop-in replacement? I don't know enough about pools to provide more info other than providing the below pics. I can get more info if required to answer your questions -- just let me know.

Have them consider a V-Green VS motor. Check with Inyopools for the correct motor for that pump.

Hi @ajw22 thanks for offering to help. Can you elaborate a little on your recommendation other than the obvious energy savings? Is the VS motor integrated into their current setup more simply than a 2 speed motor or do you recommend it for different reasons?

If you get a 2 speed motor you then need to add a timer or some control to select the speeds.

As of July 2021 federal regulations will prohibit the sale of SS or 2 speed pumps over 1 HP.

The VS gives a lot more flexibility to run at whatever speeds work for their pool setup.

Ok that makes sense. Will they need the rouond flange connector like in the link you provided? The reason I ask is because the motor>pump connector looks square-ish to me but that could just be my inexperience talking. Here's a better pic.

Square or round?

 

[ajw22]

Yup, that is why I said check with Inyopools on the correct model for the pump.

Thanks again for the help. This is the pump that they recommended:
