What are the types of pump impellers?

Dear Sharif,

Impeller particularly is defined in Centrifugal pumps. We can mainly classify them as following:

1- Based on duty to be performed by pump:

A. Open B. Semi-open C. Closed

2- According to vane curvature:

A. Backward B. Forward C. Straight

Note: you may find other detailed classifications. But all derived from above mentioned categories and could be practical too.

Regards

pump impellers can be classified as

On basis of flow

Axial Flow impeller

Radial Flow impeller

On basis of manufacturing\\Shape

Closed Channel impeller

Vortex impeller

Paddle impeller

Turbine impeller

propeller impeller

Mixed flow impeller

Semi open impeller

centrifugal screw impeller

Impeller types can be radial, mixed flow, axial and peripheral and are selected on the basis of the pump design and the application. see the link below for more details

There are so many types of pump impellers  but depend on classification as follows

(a) Suction, there are single and double suction impellers

(d) Blades assembly, there are open, semi-open and closed impeller

as far as i can recall we have a centrifugal pump impeller,screw type, i forgot others

Impellers may be Open, Semi-Open and Close based on their Mechanical Design and usage.

Further more, depending on the curvature of blades on the impeller, they might be Backward Curved, Forward Curved and Radial Impellers.

its so many types of pump impellers it is according to the plan witch impellers they needed,

IHG Suction ist type of a single impeller.

DP series its another type of impellers.
