Water pump impeller E4147 for 6/4D - NAH
The impeller is the main rotating component which normally has vanes to impart the centrifugal force to the liquid.Usually,slurry pump impellers have a plain or a Francis type vane.
The plain vane has a leading edge square to the back shroud,whereas the Francis vane has a leading edge projecting into the impeller eye.
Some advantage of the Francis vane profile are the higher efficiency,improved suction performance and slightly better wear life in certain types of slurry because the incidence angle to the fluid is more effective.
2) There are 3-6 impeller vanes. It depending on the size of the particles in the slurry.
3) Impeller type including Close, Semi-open and Open type. Impellers are generally closed because of higher efficiency and are less prone to wear in the front liner region. Open impellers are more common in smaller pumps or where particle blockage may be a problem or where the shear provided by an open impeller is an aid to pumping froth.
4) We can also produce the non-standard impellers for some special situations.
a)Pumping coarse coal
b)Pumping fibrous material
c)Reduced diameter impellers
d)Reduced eye impellers
