Reasons for the decrease in flow rate of centrifugal pumps.
Thread Content
When two centrifugal pumps operate together for a period of time and then one of them is stopped, it is observed that the flow rate when only one pump is in operation decreases. What is the reason for this?
Open this operating outlet valve a bit more, or close it and adjust it again!
When two pumps operate simultaneously, their flow rate is lower than that of a single pump.
Are the 2 units connected in series or in parallel?
The flow rate decreases when only one pump is operating compared to when two pumps are running simultaneously, and this is due to a reduction in power.
The question is phrased a bit vaguely; of course, two devices will have more traffic than one. As long as the parameters on the pump’s performance curve are met when it is operating alone, it is considered to be functioning properly!
