Abstract
Progressing cavity devices and systems are provided. In one embodiment, a stator of a progressing cavity device includes metal plates with apertures that are rotationally offset to form a winding rotor conduit for receiving a rotor of the progressing cavity device. A layer of elastomer can be provided on edges of the apertures of the metal plates in the winding rotor conduit, and the stator can also include a gas breakout port through the metal plates to enable gas between the metal plates to escape the stator. Additional systems, devices, and methods are also disclosed.
