What type of pump?

I suspect this is just something they have found with experience that their particular unit doesn't work well above that limit.

it is ITT centifuge pump, with head 44.8m, flow rate 5m3/hr, oil density similar to water.

I also think it is an experience value, coming maybe from experiment. how to prove it to client is a question.

Basic theory of the effect of high viscosity on centrifugal pumps you will find here,
show your client where you are on the charts.

It's a rule of thumb. I would not expect to see any difference between the performance of the pump under those two conditions.

As a chem eng/metallurgist the first part of any answer I give starts with "It Depends"
