Pumps and specific gravity
Eric
Member Posts: 95
If you dead head a pump(close discharge valve) Is the pressure reading on the pump discharge affected by specific gravity of fluid.
I know pumps will pump the same height independent of SG and it that case the column height of fluid will affect pressure gauge reading. BUT if you dead head wiht a closed valve? All pump book examples show the column height and not a closed discharge valve.
My answer is NO. Only viscosity will affect dead head pressure since this is all pump sees of fluid with no flow. Any other answers?
