Abstract

A fluid pump can include a tubular housing and multiple stator sections. Each of the stator sections has a helical stator profile formed therein. Deformation of the housing secures each respective stator section in the housing. A method of producing a fluid pump can include securing multiple stator sections to each other, each of the stator sections having a stator profile formed therein, and securing the stator sections in a tubular housing. The securing steps can be performed without any welding. The step of the securing the stator sections in the housing can include deforming the housing toward the stator sections.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A fluid pump, comprising: 
 a tubular housing; and   a stator comprising multiple stator sections, each of the stator sections having a helical stator profile formed therein,   in which at least one deformation of the housing secures each respective stator section in the housing.   
     
     
         2 . The fluid pump of  claim 1 , in which each deformation of the housing extends into a recess on the respective stator section. 
     
     
         3 . The fluid pump of  claim 1 , further comprising a lining installed in the stator sections. 
     
     
         4 . The fluid pump of  claim 3 , in which the lining comprises an elastomeric material. 
     
     
         5 . The fluid pump of  claim 1 , in which relative rotation between adjacent ends of the stator sections is prevented. 
     
     
         6 . The fluid pump of  claim 1 , further comprising a rotor configured to rotate in the stator in response to fluid flow between the rotor and the stator. 
     
     
         7 . The fluid pump of  claim 6 , in which the rotor is configured to contact the stator sections as the rotor rotates in the stator. 
     
     
         8 . The fluid pump of  claim 6 , in which the rotor is configured to contact a lining in the stator sections as the rotor rotates in the stator. 
     
     
         9 . The fluid pump of  claim 1 , in which the stator sections are secured to each other without any weld. 
     
     
         10 . The fluid pump of  claim 1 , in which the stator sections are secured to the housing without any weld.
