Analytical Model for the Flow in Progressing Cavity Pump ...

As the metallic stator progressing cavity pump (PCP) operates with the stator and rotor in clearance fit, the slippage between cavities has a significant influence on the pump performance. In this paper, an analytical model is developed for the flow in the metallic stator PCP. Based on the analyses of the meshing movement and the clearance geometry inside the pump, the slippage through the ...

Rotary lobe pumps versus progressive cavity pumps | Flow ...

Progressive cavity pump operation. A progressive cavity pump displaces a fixed volume of liquid with each revolution. The rotor (a single helix design) rolls "eccentrically" within the stator (a double helix design). This design combination creates cavities, or voids, which move toward the pump's discharge end as the rotor turns.
