Dear Sir,
Need to know this in regards to throttling of the differential head.
I have a Centrifugal pump handling 4 liquids with different density and constant flow.
The flow rate is 2200 m3/hr and the differential head varies from 98.67 m to 110.13 m.
In this case, how the differntial head can be throttled when the variation in head comes.
We can throttle the flow but differential head....how ???
Please note that NO VFD is envisaged due to high cost. In this case, what should be my design case.
How the pump Vendor shall take into account the rated parameters.
