Impact of medium change on centrifugal pumps

2019-08-15View Original

Thread Content

There is a centrifugal pump that is to be reused; the original density of the fluid was 1, and it has now increased to 1.3. The flow rate and head remain unchanged – so how does the power change? How should the load be calculated and evaluated?
Reply #22019-08-15
Shaft power = flow rate x head x specific gravity / 367 / efficiency
Reply #32019-08-15
If the viscosity changes little, simply multiply the power by 1.3
Reply #42019-08-15
What is the effect of increasing viscosity from 10 to 16?
Reply #52019-08-15
This impact is minimal and can be ignored; as long as the viscosity does not exceed 20, there is no need to make any adjustments to the efficiency or flow rate head
