This looks like snake oil to me. It's also not a "pump" in any sense so this probably isn't the right forum. I would try one of the...

Following Pierre's comment, discharge pressure changes at the square of the speed change and flow at the ratio of change, this can...

Correct, crystal ball gazing and guess work for the want of a bit of useful data.

How about you tell us what the operating flow and head is for the system your pumping on. At the moment noboby has a clue as to what is...

What duty?, the Q / H stamped on the pump name plate.

That results in higher amps.

And it's viscosity? It's like squeezing blood out of stone getting usefull data.

Igpm or usgpm?

Looking at the flow and head on the pump plate, we can assume this is probably performance at its BEP, calculating the power required at...

It will be the power required to operate anywhere on its designed performance curve, that will be maximum water horsepower divided by...

It's pretty clear what the voltage supply should be, 415v 50 htz as per the motor data plate.

Your not using like terms, the pump from India is more than likely Imp gpm and you're using 3960 that is used for USgpm.

Or running near to end of the curve requiring in excess of 3.7Kw. It's interesting that it's always the pump or motor at fault, never...

Right, the pump may be operating at the end of curve. I stated such in one of my e-mails above that the actual operating point is not...

A lot of these small off the shelf pumps are supplied with motors sized to operate across their performance curve and and more than...
