Abrasive handling submersible pump assembly diffuser

A submersible pump assembly diffuser comprising:

• a concave diffuser bowl comprising:
• a floor;
• an inner wall extending axially about an inner diameter of the floor;
• an outer wall extending axially about an outer diameter of the floor;
• and
• a plurality of blunted pie-shaped wedges arranged about the floor of the concave bowl, each of the plurality of blunted pie-shaped wedges protruding axially from the floor and extending radially between the inner wall and the outer wall, wherein a thickness of each of the plurality of blunted pie-shaped wedges measured in a circumferential direction increases from the inner wall to the outer wall, and wherein a blunted side of each of the plurality of blunted pie-shaped wedges faces the inner wall.

An electric submersible pump assembly stage comprising:

• a rotatable impeller;
• and
• a co-axially mounted diffuser comprising:
• a diffuser bowl comprising a plurality of diffuser bowl wedges having a blunted pie-shape, each of the plurality of diffuser bowl wedges protruding axially from a diffuser bowl floor into a cavity between the rotatable impeller and the co-axially mounted diffuser such that each of the plurality of diffuser bowl wedges protrudes into a path of pumped solid-laden fluid, wherein each of the plurality of the blunted pie-shaped wedges extends radially between an inner wall and an outer wall of the diffuser bowl and a thickness in a circumferential direction of each of the plurality of the blunted pie-shaped wedges increases towards the outer wall.
