Investment Casting Impeller

What is impeller? The impeller is an energy supplying device. It is a rotating component of a centrifugal pump. It consists of a number of curved blades. Its main function is to transfer the mechanical energy of the motive force directly to the liquid to increase the static pressure of the liquid.

  The manufacturing methods of the impeller mainly include sand casting, precision casting, welding, etc. The performance of the impeller size, shape and manufacturing precision is greatly affected.

  Investment casting impellers are the most advanced now. We are a Chinese impeller investment casting foundry and supplier.

Impeller types

  Impeller design is the most significant factor for determining performance of a centrifugal pump. A properly designed impeller optimizes flow while minimizing turbulence and maximizing efficiency. It has 3 main types: Open impeller. Semi-open impeller . Closed impeller.
