The current owners of the Phil Wood company sometimes do make misleading statements, like "We have often been credited with inventing the cartridge bearing bottom bracket" in an interview in the Reader No. 40. (Note how they don't claim that they invented it... Cartridge bearings in hubs and BBs have been around at least since the 1930s.) That one really bothered the historian in me!
I wouldn't be surprised if the submersible pumps used the same bearings, but I suspect that they have external seals that make sure the bearings don't get wet in the first place! The bearings on Phil hubs really need external bearings – they aren't designed to be exposed to the elements. Look around any industrial application (or even your car) – you won't find cartridge bearings exposed to the elements, unless the piece of machinery is only used indoors.
