The motor nameplate rated voltage is intended for use with the
following nominal system voltages (modern practice):

nameplate   system
  115 VAC   120 VAC
  200 VAC   208 VAC
  230 VAC   240 VAC

The motor labeled for 110V is intended to run in the 120 VAC system.
I would suggest starting one motor at a time.  Many jurisdictions
will not allow a pressure switch to start a power source.  Time delay
would be better course.

Good luck,
