WRT®
Wear Reduction Technology

The new Warman® WRT® is a superior upgrade for your existing

Warman® AH pump designed to enhance efficiency and improve
wear performance

Warman® WRT® advanced technology

• Increased wear life – the impeller
throatbush combination will increase wear
life between 30% and 50%
• Power savings – lower pump power
consumption
• Cost reduction – higher pump efficiency
sustained over a longer pumping operation
time
• Retrofit – new design parts retrofit to your
current Warman® pump
• Lower NPSH requirements – results in
enhanced hydraulic performance and
extended wear life
• Material combinations – rubber or metal
part combinations available

New 4 vane impeller and matching

throatbush design improve wear
performance assisting our customers in
reducing their total ownership cost
After extensive research and development Weir Minerals
offers advanced technology to reduce total cost of ownership

Years of actual wear data on the popular Warman® This has resulted in the introduction of the new WRT®
AH pump design has enabled our design engineers to impeller and throatbush design. The new impeller
use a novel integrated design approach, comparing design incorporates a unique vanelet on the back
this “real world” data with our Computational Fluid shroud which streamlines the flow through the
Dynamics (CFD) simulation to obtain correlation impeller. This new combination provides significant
between predicted and actual results for the standard improved wear life, with rigorous field testing
5 vane slurry impellers. showing increases in wear life of up to 50% on the
previous design. This improvement also gives higher
efficiency and therefore lower absorbed power and
improvements in the NPSH performance.
