How to choose between them
Federal efficiency rules made variable speed the norm for standard-size in-ground filter pumps from 2021. Running slower for longer uses far less energy for the same turnover, and the pump speeds up for cleaning, heating or water features.
A pump's maximum flow is measured with almost no resistance; at your pool's real pipe and filter resistance it moves less. The pump size calculator works out the flow your pool needs.
