Abstract
A selectively configured volute for incorporation into a centrifugal pump of the volute type is disclosed for use in processing heavy duty slurries that are characterized by containing particularly large and/or abrasive particulates that are known to degrade the pump casing or pump casing liner. The configured volute of the present invention is particularly suitable for use in connection with the use of an impeller having expelling vanes that aggressively pump out slurry from the seal face of the pump. The configured volute of the present invention provides resistance to wear when processing heavy duty slurries and provides stable flow performance and improved pump performance.
