esshup,
I looked up a few 2HP pumps and they are all about the same as far as amps go.
Average for a 230Volt motor is: FLA = 9.9, Service factor amps = 12.2 and start up amps = 49.4.
You could expect to operate at 2.28 KW. That is if you were drawing FLA all the time.
Estimate about 6 bucks per day at 0.11/kwh to be close.
