Abstract
A stator assembly for a progressing cavity pump is provided. The stator assembly includes a number of stator laminates having a planar body defining a primary, inner passage and a number of outer passages, the outer passages disposed effectively adjacent the inner passage whereby the inner passage is at least partially defined by a band, wherein the band is outwardly flexible. The stator laminates are coupled to each other in a stack wherein the stator laminate body inner passages define a helical passage. The helical passage is a flexible helical passage.
Claims4
A stator laminate for a progressing cavity pump stator assembly comprising:
- a planar body defining a primary, inner passage and a number of outer passages;
- said outer passages disposed effectively adjacent said inner passage whereby said inner passage is at least partially defined by a band;
- wherein said band and outer passages comprise a flexibility assembly:
- wherein said number of outer passages include circumferentially adjacent passages;
- said number of outer passages includes a number of slots;
- each of said slot including a first end, a medial portion, and a second end;
- and said slots defining a number of support elements between said adjacent slots.
A stator assembly for a progressing cavity pump, said progressing cavity pump including an elongated helical rotor, said stator assembly comprising:
- a number of stator laminate bodies, each of said stator laminate body is planar defining a primary, inner passage and a number of outer passages, said outer passages disposed effectively adjacent said inner passage whereby said inner passage is at least partially defined by a band, wherein said band is flexible;
- said stator laminate bodies coupled to each other in a stack wherein said stator laminate body inner passages define a helical passage and said stator laminate body outer passages define helical outer passages;
- wherein said helical passage includes a flexibility assembly;
- each said stator laminate body number of outer passages includes a first set of outer passages and a second set of outer passages;
- said first set of outer passages are disposed about the associated inner passage;
- and
- said second set of outer passages are disposed about the associated first set of outer passages.
