Should the inlet pressure be taken into account when calculating the material head of the pump in the pump technical specifications?

I have a question: if the inlet pressure of the pump is 3.9 Mpag, the density of the material is 1000 KG/m3, and the desired outlet pressure is 6.4 Mpag, then should the head specified in the pump’s technical data sheet be 250 meters or 640 meters?

The pressure difference is calculated as 2.5 MPa

250 meters; if a variable frequency drive is used with the pump, a higher head can be achieved
