Tobee® Warman slurry pump impellers
Tobee® slurry pump impellers
are interchangeable with Warman slurry pump impellers, 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 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 as illustrated (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.
The impeller design is crucial as it influences flow patterns and ultimately, wear rates throughout the pump.
The wide range of Tobee standard impellers cover most slurry pumping duties or special non-standard designs are also available. Some examples of standard and non- standard impellers are shown in follwing:

Some typical examples of the need for the non-standard impellers are:
a) Pumping coarse coal
Large particles may cause blockages with a standard 5 vane closed impeller. A special large-particle 4 vane impeller may be required.
b) Pumping fibrous material
Long Fibres may get caught around the vane entrance of standard impellers. A special chokeless impeller can be used for these duties.
c) Reduced diameter impellers
In some special cases, reduced diameter impellers are required but are generally avoided as impeller wear is higher than with full diameter impellers as illustrated in Figure 1-3.
d)Reduced eye impellers
In some extremely high wearing applications such as mill discharge, a special impeller with a reduced eye can prolong impeller wear life.

Range of Applications of Slurry Pumps:
Slurry
pumps are used widely throughout the beneficiation section of the
mining industry where most plants utilise wet separation systems. These
systems usually require the movement of large volumes of slurry
throughout the process.
Slurry pumps are also widely used for the disposal of ash from thermal power plants. Other areas where slurry pumps are used include the manufacture of fertilisers, land reclamation, mining by dredges, and the long distance transportation of coal and Minerals.
Increased global focus on environmental and energy constraints will certainly generate much wider uses for slurry pumping in years to come.
