Which of the following are the classifications of centrifugal pumps?

Centrifugal Pumps :

•  A centrifugal pump is a rotary machine that transforms kinetic energy into the pressure head of the fluid.
• A Centrifugal pump is a mechanical device that is used to increase the pressure of the fluid.
• Pressure rise of the fluid happened though imparting the prime mover energy to the impeller of the pump.
• When the impeller gets rotated from any external prime mover then the energy of the prime mover is transferred to the fluid and the rotary velocity of the fluid gets increased because of the diverging section of the impeller this kinetic energy is converted into the pressure head.
• Centrifugal pump and Francis turbine working is just opposite to each other.

Classification of Centrifugal Pumps Based on the Flow Type :

• Accordingly, radial, Axial, and Mixed flow are three types of centrifugal pump

• Different designs of centrifugal pumps according to the specific speed ranges 

Classification of Centrifugal Pumps Based on Shaft Orientation: 

• Accordingly, centrifugal pumps have either vertical or horizontal shaft positions.

Classification of Centrifugal Pumps Based on Impeller Position :

• Accordingly, centrifugal pumps are classified into overhung impeller pumps and between-bearing pumps.

Classification of Centrifugal Pumps Based on Casing Designs :

• Radially and axially split pump casings are two different designs 

Classification of Centrifugal Pumps Based on Number of Sections : 

• Most centrifugal pumps are single-suction designed; however, sometimes it is necessary to have double-suction designs.

Classification of Centrifugal Pumps Based on Types of Volute:

•  Pumps are divided into two categories, single-volute or double-volute, depending on their casing type.

Classification of Centrifugal Pumps Based on Number of Stages : 

• Two or more impellers can be utilized in the pump, depending on the requirements and on-site operating conditions.
