Pump run with high Viscosity liquid
Pump run with high Viscosity liquid
(OP)
Dear all,
We have a pump for hot oil with Dynamic viscosity 0.55mPa.s in 220C, for cold test run, we will have cold oil with Dynamic viscosity 8.12mPa.s.
Vendor information shows that when Dynamic viscosity is less than 20mPa.s, it will be ok. I wonder where it comes the conclusion of 20mPa.s.
May I have the answer?
Thanks.

I suspect this is just something they have found with experience that their particular unit doesn't work well above that limit.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

I also think it is an experience value, coming maybe from experiment. how to prove it to client is a question.
