TL;DR
Pump turnover is the time a pool's circulation system needs to move a volume of water equal to the entire pool through the filter, the standard yardstick for sizing pumps and setting run schedules. Residential practice targets one turnover every 8 to 12 hours, so a 20,000-gallon pool needs roughly 28 to 42 gallons per minute of actual flow.
What it means
Pump turnover is the time a pool's circulation system needs to move a volume of water equal to the entire pool through the filter, the standard yardstick for sizing pumps and setting run schedules. Residential practice targets one turnover every 8 to 12 hours, so a 20,000-gallon pool needs roughly 28 to 42 gallons per minute of actual flow. Variable-speed pumps achieve it cheaply by running longer at low speed, where power draw falls dramatically.
