Abstract
A stator is provided for a progressive cavity device. The stator includes modular stator segments connected together. Each stator segment includes a front surface, a rear surface, and an internal helical cavity extending longitudinally from the front surface to the rear surface. Each stator segment also includes a set of bolt holes extending longitudinally from the front surface to the rear surface, and a set of connection holes opening at the front surface and extending at least partially longitudinally from the front surface to the rear surface. Bolts, inserted through the bolt holes into connection holes of an adjacent stator segment, connect the stator segments and align the internal helical cavities to form a continuous helical chamber.
