A question about the high viscosity oil

The only solution I can think of is HEAT. At 10 degrees any ISO 680 lubricant is going to flow like honey and is will be very difficult to pump. Your lubricant storage tanks should be located in a climate controlled area and kept at normal room temperature. I work on a climate where it gets 30 below in the winter. Our lubricant storage room is inside and if we receive a new drum that has been outside we will set it inside overnight before attempting to pump it into the storage tank. A barrel band heater might help with warming the drum but your piping is also going to be cold and may need a heat trace.

i'm interested in the band heater.Can U give me some manufactory and model?
what is the lowest temperatur did the pump can suction the oil from the barrel?
what kind of screw pump is fitted to do this works, Twin Screw Pump or Three screw pump?

You can get a barrel band heater from WW Grainger P/N 5W662 . I have used gear type portable pumps and pneumatic piston type pumps to transfer oils this heavy. The Grainger website address is below.
