Question: 1 / 400

Which type of pump is characterized by delivering high volumes of liquid at low pressure and is not a positive displacement pump?

Centrifugal pump

The centrifugal pump is specifically designed to move large volumes of liquid efficiently at low pressures. Its operation relies on the principles of centrifugal force; as the impeller rotates, it imparts kinetic energy to the liquid, causing it to flow outward and into the discharge pipe. This design makes centrifugal pumps ideal for applications where high flow rates are a priority, such as in irrigation, water supply, and many industrial processes.

Unlike positive displacement pumps, which trap a specific volume of fluid and force it through the discharge line, centrifugal pumps allow fluid to flow more freely, adjusting to varying flow demands and pressures. This characteristic of managing flow rates effectively while maintaining low pressure is what sets centrifugal pumps apart, making them suitable for many applications that require a substantial volume of liquid without the high pressures that positive displacement pumps generate.
