In a series pump configuration, what happens to head and flow?

• A. Increases Head But Similar Flow
• B. Increases Flow But Similar Head
• C. Decreases Head And Flow
• D. No Change

Answer: (A)

In a series arrangement, the same flow passes through each pump, so the flow rate through the train is essentially the same as for a single pump. Each pump contributes its energy head to the fluid, so the total head is the sum of the individual heads. As a result, the system can develop a higher head while the flow remains essentially unchanged at the same operating point. This is why the correct description is that head increases while flow stays similar.
