Double suction pumps are capable of pumping approximately how much flow and head?

Double suction pumps are capable of pumping approximately how much flow and head?

• A. 5,000 gpm and head 200 ft
• B. 10,000 gpm and head up to 350 ft
• C. 15,000 gpm and head 500 ft
• D. 20,000 gpm and head 300 ft

Answer: (B)

Double-suction centrifugal pumps are built to move large volumes of water at moderate heads. Their design feeds the impeller from both sides, which increases the flow capability while keeping efficiency high and reducing the chance of cavitation at the suction side. In typical water distribution practice, a single large double-suction pump can deliver about 10,000 gallons per minute and develop up to roughly 350 feet of head. This combination—around 10k gpm with up to 350 ft head—reflects common performance for high-capacity distribution pumps. If you need significantly more head, you’d look at different pump configurations or multiple units; for much smaller flows, a smaller pump would be chosen.
