You could probably replace the transformer with a single phase one provided the overall rating is sensible. Or replace the whole PSU.

If it is a DC motor with the usual thyristor controller then that will probably run happily from single phase with some careful re-wiring. Actually checking the manual you referenced above it has a single phase mains connection anyway!

The coolant pump is more of a problem but its power is probably low and you can run 3 phase motors from single phase using some capacitor trickery - or use a cheap inverter - or replace the motor - or dispense with pumped coolant!
