Abstract
The present invention relates to a resilient material lined stator and method of forming. A method of forming a resilient material lined stator can include disposing a resilient material tube 400 with a profiled helical inner surface 401 into the bore of a body 420. A cast material 410 can be disposed therebetween. The cast material 410 can bond to the body 420 to form a resilient material lined stator or the body 420 can be removed. The cast material 310 can include a conduit 312 or conductor 314 extending therethrough. The cast material 310 can include a pathway 316 formed therethrough. The resilient material can be an elastomer.
