Abstract
A progressive cavity assembly can include a stator having a tubular housing and a stator section having a helical stator profile formed therein. At least one deformation of the housing secures the stator section in the housing. A method of producing a progressive cavity assembly can include providing a stator section having a stator profile formed therein, and securing the stator section in a tubular housing. The step of securing the stator section in the housing can be performed without any welding. The step of securing the stator section in the housing can include deforming the housing toward the stator section.
