Abstract (en)
[origin: WO2018111585A1] A wellbore pump (100) that includes a pump housing (114), a pump stage (126) positioned within the pump housing (114), the pump stage (126) including a stationary diffuser (112a, 112b) and a rotating impeller (118) positioned within the diffuser (112a, 112b), a pump head (102) attached to a first end of the pump housing (114), a compression tube (104) attached between the pump head (102) and the diffuser (112b), the compression tube (104) increasing a contacting force to prevent rotation of the diffuser (112b) with the impeller (118), and a ring-shaped memory material (108) positioned around the diffuser (112b), the memory material capable of reversibly expanding from a temporary state to a permanent state in response to wellbore operating conditions to form an interference fit with an inner surface of the pump housing (114) during operation of the wellbore pump under the wellbore operating conditions.
