ABSTRACT:
A progressing cavity pump assembly includes a collar assembly connecting a housing and a tubing string, with the collar having an inside diameter upset and the rotor having a rotor head axially spaced from a rotor helix, with the rotor head having an outer diameter forming a stop adapted to land on the inside diameter upset. A method of timing a progressing cavity pump assembly includes providing a collar assembly having an inside diameter upset, movably connecting the collar assembly and the housing, providing a rotor having a rotor head axially spaced from a rotor helix, with the rotor head having an outer diameter forming a stop, selectively adjusting the relative position of the collar assembly and the housing to form a pathway substantially corresponding to the rotor helix, landing the stop on the inside diameter upset, and fixing the relative position of the collar assembly and the housing.
