Creates an hypocyclic helical rotor and stator. Moineau pumps are often used for pumping viscous media, such as mud, clay, slurries, because as progressive cavity mechanisms, they pump the same volume regardless of inlet/outlet pressure or viscosity.  

The rotor will typically need a shaft added. See the provided links below for various solutions to eccentrically driving the rotor.

The generated stator is actually the solid model of the stator cavity. As the stator is frequently molded out of silicone, this allows the user to use the generated model for creating the mold tool, as well as latitude in creating the external stator geometry (from which the generated stator body can be cut via a Boolean operation).
