Mixed flow pumps and centrifugal pumps are both fluid conveying equipment, but there are some significant differences between them. The following are the main differences between mixed flow pumps and centrifugal pumps:

Working principle: Centrifugal pumps mainly rely on centrifugal force to discharge fluid from the pump. When the motor drives the impeller to rotate, the fluid is ejected outward from the center under the action of centrifugal force and finally discharged through the pump body. A mixed flow pump is between a centrifugal pump and an axial flow pump, which combines centrifugal force and axial thrust to allow fluid to flow both radially and axially within the impeller.

Impeller structure: The impeller of a centrifugal pump usually has radial blades, and the fluid flows radially inside the impeller. The impeller of a mixed flow pump has special diagonal blades, which allow the fluid to have both radial and axial flow components inside the impeller.

Head and flow rate: Centrifugal pumps are usually suitable for applications with medium to low flow rates and high head, while mixed flow pumps are suitable for applications with medium flow rates and medium head. In contrast, mixed flow pumps have a lower head but a larger flow rate.

Efficiency: Under the same operating conditions, the efficiency of a mixed flow pump is usually higher than that of a centrifugal pump because the flow loss of the mixed flow pump is smaller.

Installation method: Centrifugal pumps are usually installed horizontally, while mixed flow pumps can be installed horizontally or vertically.

Application areas: Centrifugal pumps are widely used in water supply and drainage, fire protection, heating and other systems, covering various industries. Mixed flow pumps are mainly used in fields such as agricultural irrigation, urban water supply and drainage, and water conservancy engineering, and are suitable for scenarios with high flow rates and medium head.

In summary, there are certain differences between mixed flow pumps and centrifugal pumps in terms of working principles, structures, performance, and application fields. When choosing a pump, it is necessary to select the appropriate pump type based on specific operating conditions and requirements.
