Small DC-motor

I'm looking for a small compact DC motor to run a blower for a fuel cell application
I need it to be very well sealed (Submersible) and highly dependable, anyone out there in the field with an idea of which company I should contact for this?

I'm talking dimensions of :
Diameter 1.5 inches
Length 2.0 inches

pressfitted inside a small heat sink.
thanks

Suggestion: Visit

http://www.thomasregister.com

and type dc motor under Product/Service
This returns some dc motor types, e.g. Motors: Brushless DC offered by 181 Companies with their contact info and product offer (Emerson, Kollmorgen,.........). Usually, secretaries take it from there.

Such motors are available. The Thomas Register or W.W. Grainger are both good sources. However, my first thought is whether this application will require a UL listing and possibly an explosion proof motor. I am not well versed in fuel cell applications so if this is an erroneous answer, I apologize in advance.
