Dual-speed pumps are in the same electrical category as single-speed pumps but the main difference is that they run at a “High Speed and a “Low Speed”. Dual-speed pumps also cost a bit more than single-speed pumps as far as upfront cost is concerned. WebA pool pump that uses 1119 Watts per hour at 3450 RPM (single speed pump RPM's) will use only 140 Watts at 1725 RPM. At 862.5 RPM's the motor is using only a scant 17.5 Watts. Most variable speed pool pumps go as low as 500 to 600 RPM's so you can really see how this can reduce on the electricity that you use.
