Pump for transporting low-temperature media in low-temperature environments
Thread Content
The ambient temperature ranges from -30 to 40 degrees Celsius. The medium is ethylene glycol, with a temperature range of also -30 to 40 degrees Celsius; its concentration is around 60%. We use pumps made from stainless steel for transportation. I wonder whether it’s necessary to use low-temperature grease for the bearings. A moisture-proof heating strip is installed on the motor. Experienced colleagues, what effects might pumps made from 304 or 316 steel plates experience in low-temperature environments? Could they become brittle? What issues should be taken into consideration when working in low-temperature conditions and transporting low-temperature media? :)
This is room temperature; it’s not some low temperature at all
