Looks like you're making reasonable progress.

One thing I meant to mention in my last post, is are you sure the coolant pump will run on single phase? Just because it's marked to work on 240V, it will most likely be for 3 phase 240V.
AC induction motors that run from single phase require a start or run capacitor, whereas 3 phase don't, as well as having different internal coil wiring, so it's highly unlikely the same motor will run from both 3 phase and single phase.
