First claim
Opening claim text (preview).
1 . A pump comprising: at least one impeller; at least one diffuser; and at least one wear ring positioned between the at least one impeller and the at least one diffuser and removably coupled to the diffuser, the at least one wear ring having a plurality of radially extending clutch members, wherein the clutch members are configured to hold a portion of the at least one diffuser. 2 . The pump of claim 1 , wherein the clutch member comprises a first and a second tab portions wherein the first and second tab portions are spaced art. 3 . The pump of claim 2 , wherein the first tab portion is an extension of a tab, first tab portion extending from a first side of the at least one wear ring. 4 . The pump of claim 3 , wherein the at least one wear ring comprises three tabs mutually angularly spaced on the first side. 5 . The pump of claim 4 , wherein the tabs are mutually angularly spaced at an angle (α) of 120 degrees. 6 . The pump of claim 2 , wherein the second tab portion is part of a lip extending laterally from an outer surface of the at least one wear ring. 7 . The pump of claim 6 , wherein the lip extends around the at least one wear ring. 8 . The pump of claim 1 , wherein the at least one wear ring is composed of a deformable material. 9 . The pump of claim 1 , wherein the at least one impeller contacts the inner surface of the at least one wear ring. 10 . The pump of claim 1 , wherein the pump is a multi-stage pump comprising a plurality of impellers; a plurality of diffusers, and a plurality of wear rings.
