  • Patent number: 10738794
    Abstract: A technique employs a system and methodology for improving sand control in pumps. The technique may be used in centrifugal pumps by providing uniquely constructed rib feature to facilitate sand control and thus reduction of erosion due to sand in the pumped fluid. The improved sand control is useful in centrifugal pumps employed in a variety of oilfield applications, such as in electric submersible pumping systems positioned downhole in a wellbore to pump oil or other fluids. The rib feature may be used in combination with a shield and arranged along diffuser bowl walls or other diffuser walls within sequential pump stages.
