Hi all,
I have a situation where the pumps are pumping outside of its curve, max flow.
the client has no problem with throttling the outlet to move the duty point back on the pump curve, he knows all about the energy losses and don't care. I was concerned about the pressure drop required to reach the required duty point, I'll need approximately 3.4bar drop.
We will get this by semi closing a butterfly valve. Will this pressure drop cause cavitations? Even if it does and the only thing that will get damaged is the valve and a piece of pipe then no problem. Does this valve need to be away from the pump “few meters” to prevent cavities from affecting the pump it self?
Is there something else I should worry about?
Regards.
