  • Patent number: 7470106
    Abstract: An apparatus and method for a slurry pump having improved erosion characteristics. The pump comprises a rotatable impeller having at least one impeller vane, an impeller shroud having an inlet for conveying slurry to the impeller and an outlet for discharging slurry accelerated by the impeller, and a pump housing having a side wall with a recess therein, said recess being deep enough to therein matingly receive said impeller shroud outlet so as to form a joint surface producing a sufficient impingement angle between the impeller shroud outlet and the pump housing side wall to substantially reduce erosion thereon by the accelerated slurry.
