You would need the motor blocks and propeller. Where do you live, the Hz is the main issue, not the volts. if your power is 115V 50Hz it is best to use the 220V 50Hz with a transformer and vice versa, on 220V 60Hz, the 115V 60Hz version with transformer is the way to go. Tunze now offers some pumps in 220V 60Hz and 115V 50Hz.
