Hi Everyone.  I need to pump -30C axle oil at 2 gpm with a 120 Vac
circuit available for use.  Pump will be close to oil reservoir in the
-30C ambient.  Eventually, this oil will warm up to 120C in the -30
ambient.  I have never had success pumping this cold, except by using
air pressure to push it through the circuit.  This isn't an option at
this time.  Any suggestions?

Thanks for any input...

I would be looking for a progressing (progressive) cavity

have no valves or other restrictions in their entries.
