Head and flow rate issues of vertical centrifugal pumps
Thread Content
We have two sets of vertical centrifugal pumps here, Phase 1 and Phase 2; they have the same head, but one has a flow rate of 20 while the other has 40. The pump with the lower flow rate cannot be used for transporting liquid outside. Could you all, who are more experienced, advise me on how to carry out the calculations? Tell me why it can’t be delivered Provide the brands of two centrifugal pumps.
Please provide the diameters of each export pipeline
It can be delivered unless the system pressure is higher than the pump’s output pressure. The key is the system pressure after the pump. For reference.
Check if there is a significant difference in the pump outlet pressure!
Ask the supplier manufacturer; it might be related to the product selection, as the pump’s capacity does not match the conditions at the site. . . .
