Mixed Flow Pumps

What is a mixed flow pump?

A type of pump that mixes features of radial flow and axial flow pumps.

Radial flow pumps are in-line centrifugal pumps that operate on a horizontal plane in relation to the flow direction of the water. Axial flow pumps are the opposite—they are in-line pumps that work on a vertical plane in relation to the water. Mixed flow pumps are a cross between the two. The impeller sits within the pipe and turns, but the turning mechanism is essentially diagonal, using centrifugal force to move the water along while accelerating it further with the push from the axial direction of the impeller. This creates enough force to generate high rates of flow.

Where are they used?

Mixed flow pumps are primarily used in applications requiring a high level of flow combined with relatively low discharge pressure. There are a number of industrial applications where this type of pump can be useful. They are also used to help propel watercrafts, such as jet skis.

Other related Pump Types include: vertical pumps, water pumps, waste water pumps, circulating pumps.
