I've attached a 220v pump to a halogeen spot trimmer, making it go from 160 to 230v.
It only started to run at 190, same noise level (even higher) , less head and my trimmer got damm hot!

To spped it up or slow it down you need to change the freqency, and those things are quite expensive. Only changing the voltage will give it less power, making it stop spinning sooner.

If you want variable, why not go for 12v pumps?
