Two or more pumps discharging into the same system produce which configuration?

• A. Parallel Pump
• B. Series Pump
• C. Deadhead Pump
• D. Single Pump

Answer: (A)

When multiple pumps discharge into the same system, they are in parallel. The outlets are connected to the same discharge line, so the system pressure (head) is essentially the same for each pump, and their flows add together. In practice, the overall flow capability increases while the discharge pressure remains at the level set by the system (roughly the same as a single pump at that operating point). If pumps were arranged in series, the pressure would rise while the flow stays about the same. The other options don’t describe this situation.
