Abstract
A stator and a method of manufacturing at least a portion of a progressive cavity motor or pump include disposing a cylindrical shell within a cylindrical housing, disposing a stator mold within the cylindrical shell, disposing an elastomeric material between the stator mold and the cylindrical shell, removing the stator mold from within the elastomeric material, thereby forming an elastomeric material layer having a stator profile within the cylindrical shell, and removing the cylindrical shell from within the cylindrical housing, thereby forming a cartridge having the elastomeric material layer disposed within the cylindrical shell.
