Hallo Yashpal,
i would say that the idea of Anand to replace the Stage 1 pump (~100 HP) and eliminate stage 2 pump is worth to think about. Normaly if you replace a 20 year old pump into a modern one (think about the synchronous motor type) the efford will be amortized within a few years and then you get into a winning-zone. And all the coordination-problems inbetween the 2-pump system will be obsolete. But the indispensable condition is, that your pipe-system in section 1 is in a proper pressure-stage.
