Abstract: A method of assembling progressing cavity pump of the Moineau type having a helically externally threaded rotor coacting with an internally helically threaded stator. In a Moineau pump where the pump casing is a singular tubular unit, the stator is normally bonded to the inside of a tubular housing with an adhesive. When such pumps are used to pump a corrosive fluid, such as caustic soda, the adhesive can be attached and the stator thus freed to rotate. To prevent the stator from rotating, studs are driven through the housing and into the stator. The location of these studs can be pre-marked by use of a suitable template. Also, the driven studs can be welded to the housing to prevent leakage or loosening.
