I suspect that you meant a variable speed pump will limit the amps at 115 volts vs. 230 volts, which is what happens with the Superflo vs.
From the manual, the maximum amps at 115 volts is 13.2. So, that limits the watts to 1,518.
The maximum amps at 230 volts are 11.5. So, that limits the watts to 2,645.
The pump must be reducing the rpm as needed to keep the amp draw below 13.2 when the voltage is 115.
Looking at the Superflo VS pump specs: 115-volt: WEF 7.3 THP 2.2 230-volt: WEF 6.6 THP 2.2 Does this mean it is more efficient at 120V than 240V? I know I'll get a higher flow rate at high speeds at 240V, so I may go that route anyways. Any reason to go for one voltage over the other...
