A vertical mixed flow pump is a LEO Pump type of centrifugal pump that is designed to move water vertically in large volumes with low to medium pressure. The impeller of a vertical mixed flow pump is shaped like a propeller, and it sits inside a volute or diffuser.

As water enters the pump, it is directed into the impeller, which causes the water to flow in a radial direction before being discharged vertically through a diffuser. The design of a vertical mixed flow pump allows it to handle large volumes of water with low head requirements, making it ideal for applications such as irrigation, drainage, and flood control.

Vertical mixed flow pumps are commonly used in agricultural and industrial applications, such as water treatment plants, sewage treatment plants, and power plants.
