Brian -- My gut is that it's reasonable to expect a UL/CSA marking on a 3-phase 460 VAC motor, but that listings for pumps are quite a bit rarer.
Are there unique hazards associated with the pump should it fail? If not, I'd concentrate on the motor marking. Contact me off this list-serve if you'd like to discuss more.
