Impeller Types:

The impeller has three types: closed impeller, open impeller, and semi-closed impeller.

Slurry Sand Pump Part- Closed impeller

There are cover plates on both sides of the impeller, and there are 4-6 blades between the cover plates.When the blade is bent in the opposite direction to the direction of rotation of the impeller, it is called a shield curved blade.Generally, the blades of the impeller are all curved blades. This closed impeller is the most efficient and widely used for conveying clean liquids without solid particles and fibers. Closed impellers are available in single and double suction types.Double suction impeller has larger infusion volume than single suction impeller

Slurry pump accessories - open impeller

There is no cover on both sides of the impeller, and the blades are connected to the hub through the ribs. The impeller has a simple structure and is easy to manufacture, but has low efficiency. It is suitable for conveying liquids containing more suspended solids or fibers.

Slurry pump accessories - semi-closed impeller

This type of impeller has only a rear cover

It is suitable for transporting liquids that are prone to precipitation or contain suspended solids.Its efficiency is between the open and closed impellers.

Impeller material:

According to different needs, the impeller can be made of high chrome, hard-Ni, cast iron, cast steel, stainless steel, fiberglass, plastic and other materials.

Impeller manufacturing methods include sand casting, precision casting, welding, molding, etc.

Its size, shape and manufacturing accuracy have a great impact on the performance of the pump.
