This is a submersible pump consisting of 4 “stages” connected in series. Each stage Water out is a centrifugal pump in itself. The entire pump is submerged under water. Pump stages In this submersible pump water flows from one stage to the next. The pressure (or head) pg increases as water moves through the pump, but the discharge remains constant. This is analogous to batteries connected in series. The total voltage is the sum of the voltage from each battery, but the current remains constant. Water in
