Centrifugal Pump Questions
Centrifugal Pump Questions
(OP)
Hello Everyone
I have a customer that has 2 7.5HP motors with centrifugal pumps connected to each. We have noticed that the flow rates have been not what we expected (lower). The one pump had a broken seal and upon fixing this we found the impeller was sized for a 5 HP motor. I would like to change the impellers of both pumps to 7.5 HP size but the customer is worried about the increase in the water taking ability may collapse the water intake that runs into a lake.
Is there anything I should be worried about?

You can change the impellers and still run at the same flow with a higher differential head, if you control the flowrate or the discharge pressure.
Find the new operating point to understand the significance of any changes you think you want to make.
