pump selection between Vertical Turbine (VT) and Mixed Flow Vertical (MV) pump for Raw water pumping 1

Does it meet the duty?

What power does it use to do the duty?

How much does it cost?

That's a pretty big pump though (about 4MW by my reckoning).

So even a small difference in efficiency is going to make a big difference to your OPEX.

Mixed flow pumps are commonly used in agriculture, construction, water treatment, HVAC and fire protection. They are suitable for applications where large volumes of water must be moved at low pressures.

Mixed Flow Pump

Your application is outside the application range for a mixed flow vertical pump.

Time to employ an experienced pump / system design designer, it's way beyond trying to use a free website for answers.
Give a bit more information and at least you might get a few ideas as how to best approach this application.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

That's a lot of eggs in one basket.
Maybe you would want to use multiple pumps.
I'm thinking of at least 2, maybe 4.
If the system goes down, is there any alternative?
