SINGLE-SPEED, TWO-SPEED, AND VARIABLE-SPEED PUMPS.
The three types of pool pumps available can be distinguished based on their energy efficiency. A traditional pool pump uses a basic single-speed motor; while less expensive initially, they’re loud and cause high energy bills.
Variable-speed pumps are the newest technology that offers the best in energy efficiency and programmable controls. Thanks to a highly-efficient motor, VSPs typically pay for themselves in energy savings and provide more effective filtration.
