Here at Linquip, we often get as ‘What is a mixed flow pump?’ Well, a mixed flow pump is a type of centrifugal pump that operates with a mixed flow impeller. They are commonly used in irrigation, agriculture and sewerage applications. Let’s take a look at the mixed flow pump in more detail.
What is Mixed flow pump?
So, what is a mixed flow pump and how does it work? As we know, a mixed flow pump is an industrial pump that operates with a mixed flow impeller. As the liquid or fluid moves through the impeller, the blades then push it out away from the pump shaft at an angle of more than 90 degrees. This creates enough force to produce high flow rates.
Is a mixed flow pump similar to axial and radial flow pumps?
Mixed flow pumps share similar characteristics with axial flow pumps and radial flow pumps. They are basically a mix between the two and they usually operate of a horizontal plane. In a mixed flow pump the impeller sits within the pipe itself and rotates, but the turning mechanism is diagonal. It uses centrifugal force to transport the fluid, accelerating it with the push from the axial direction of the impeller.
Horizontal and Vertical mixed flow pumps
You can actually get both vertical and horizontal mixed flow pumps, which are named to reflect whether the pump is positioned down to up (vertically) or left to right (horizontally). The choice of a vertical or horizontal mixed flow pump will depend on the task in hand and what is more appropriate.
For example, vertical mixed flow pumps might be adequate for drawing water from a well. A vertical mixed flow pump is a type of vane pump (high pressure hydraulic pumps).
What are the advantages and disadvantages of the mixed flow pump?
The mixed flow pump is a very versatile pump used in a variety of situations. It’s is essentially the pump that is a ‘jack of all trades’. Mixed flow pumps are ideal for the circulation of cold and hot water and for use in power plants. They are efficient (especially in hydraulic performance) and conserve energy well. However, mixed flow pumps are not always the lowest cost.
Where are mixed flow pumps used?
Mixed flow pumps are predominantly used in applications that require a high level of flow combined with relatively low discharge pressure.
- Lift irrigation and drainage of agricultural lands
- To pump clean, turbid and slightly contaminated liquids for example in sewage applications
- Handling sea water and water supply
- Moving cooling water in thermal and nuclear power plants
