A progressive cavity pump is a positive displacement pump in which the moving part is composed of discrete cavities around an axis. Cavities get the fluid during intake and displace it along the chamber to the output with a positive pressure.
It is different from a screw pump as the cavities actually moves here. A screw doesn't have cavities, see pump_mechanism=screw
Such pumps are mainly used in industry with mechanical_driver=electric_motor to move viscous fluids, you won't find them pumping water very often.
