A progressive cavity pump is a type of positive displacement pump and is also known as a progressing cavity pump, progg cavity pump, eccentric screw pump or cavity pump. It transfers fluid by means of the progress, through the pump, of a sequence of small, fixed shape, discrete cavities, as its rotor is turned. This leads to the volumetric flow rate being proportional to the rotation rate (bidirectionally) and to low levels of shearing being applied to the pumped fluid. A common misconception among laymen is that the progressive cavity pump is a simple auger. This type of pump is by no means an auger. This misconception is usually caused by a lack of understanding of the basic principles of pump operation.
