Alan G Wild, Kamran Z Mirza: Progressing cavity pump having less compressive fit near the discharge. Robbins & Myers, Thompson Hine & Flory, March 3, 1998: US05722820 (27 worldwide citation)

A progressing cavity pump is provided in which the compressive fit between the rotor and stator is gradually reduced with the distance from the suction end of the pump. This gradual decrease in compressive fit allows for increased slippage near the discharge end of the pump, resulting in better dist ...
