The FAM12147R55 Impeller is one of the most important parts for slurry pump. Centrifugal slurry pumps need impeller to produce the centrifugal force which transfer the slurries. The centrifugal force is produced by the impeller which rotates to a certain speed, As 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 type impeller exhibits better wear life characteristics in very coarse slurry applications or where the mould design precludes the Francis type where an elastomer impeller is required.

The number of impeller vanes usually varies between three and six depending on the size of the particles in the slurry.

Slurry impellers are more commonly of the closed type (with a front shroud) but open type impellers (without a front shroud) are sometimes used for special applications.

Impellers are generally closed because of higher efficiencies 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.

Another feature of slurry pump impellers is the pump out or expelling vanes on the back and front shrouds. These perform the dual function of reducing pressure (thus inhibiting recirculating flow black to the impeller eye, and reducing stuffing box pressure) and keeping solids out of the gaps between the casing and impeller by centrifugal action.
