PROGRESSIVE CAVITY PUMPS

The basis of any Progressive Cavity Single Screw Pump is a power section which usually consists of a metal rotor (n-start external helix) and a rubber stator (n+1-start internal helix). Rotation of the rotor inside the stator creates sealed cavities that progressively move from suction to discharge side of the pump producing differential pressure.
