Double suction pump head maximum is up to how many feet?

Double suction pump head maximum is up to how many feet?

• A. 250 ft
• B. 350 ft
• C. 450 ft
• D. 550 ft

Answer: (B)

Head is the energy per unit weight that a pump can add to the water, measured as feet of water. A double-suction centrifugal pump is designed to move large volumes at a moderate head, and its single-stage design has practical limits on how much head it can develop. The impeller and bearing loads, along with mechanical design constraints, cap that head around 350 feet. If you need more head, you typically would use additional stages or a different pump configuration rather than pushing a single double-suction stage beyond this limit. So the maximum head for a double-suction pump is about 350 feet.
