Can a self-priming pump be used for high-temperature oil (around 300°C)?
Thread Content
As the title suggests: A manufacturer is transporting high-temperature oil (around 300 degrees) and wants to use a self-priming pump. Personally, I think such high temperatures mean there is a mixture of oil and gas – can a self-priming pump draw it up? Could an experienced expert give some guidance? Thank you.
This depends on the saturated vapor pressure of the medium; it can only be determined through calculation to see if it is feasible
Vapor pressure is 0.121 MPa at 200 degrees
To achieve self-priming, the tank must be pressurized; in other words, the pressure above the liquid surface is not one atmosphere, but higher than that value
Yeah, but with pressure applied to the liquid surface, self-priming isn’t needed at all.:)
Hehe, that’s how it is – it vaporizes without pressure, and no self-priming is needed even when pressure is applied
Okay, understood! I have no choice but to communicate properly with the user{:1_90:}
