Wet rotor pump motor stator sealing liner

摘要

A sealing liner (34) for use in a pump motor (24) incorporates a radially enlarged portion (36) at one end, and a radially smaller portion (38, 40) extending from the one end to an opposed end. A length (L 1 ) of the overall sealing liner including the radially smaller portion and the radially enlarged portion is defined as a first length. A length (L 2 ) of said radially enlarged portion is defined as a second length. A ratio of the first length to the second length is between about 6.5 and about 8.5. A stator assembly, a pump and a method are also disclosed.
