What is the maximum head that a double suction pump can reach?

• A. 250 ft
• B. 300 ft
• C. 350 ft
• D. 400 ft

Answer: (C)

A double suction pump is designed to efficiently handle the flow of fluids by allowing fluid to enter the impeller from both sides, thereby minimizing radial loads on the shaft. The maximum head that a double suction pump can reach is usually higher than single suction designs due to its balanced hydraulic configuration and efficient flow paths.

The maximum head typically ranges around 350 feet for double suction pumps, as they can generate significant pressure due to their design. This capability makes them a popular choice in applications requiring high flow rates and moderate to high pressures, such as in water treatment plants and industrial processes.

While the other options present higher limits, they exceed the general operational capabilities associated with standard double suction pumps, which commonly max out at around 350 feet. This understanding is essential for selecting the right equipment for specific applications and ensuring operational efficiency.
