A form of sucker rod pumping unit in which the rotor is a chrome-plated steel external helix and the stator is a synthetic elastomer with a double internal helix permanently bonded into a steel housing. Rotation of the rods by a vertical spindle electric motor at the surface causes the rods to stretch a predetermined amount to maintain the rod string in tension. It also causes a cavity containing well fluid to progress upward. The system is a rotary positive-displacement unit. 2, record 1, English, - progressive%20cavity%20pump

Pompes à rotor hélicoïdal excentré. Elles sont composées de deux engrenages hélicoïdaux : l'un, le rotor, en métal, tournant à l'intérieur de l'autre, le stator, en caoutchouc. Le rotor est un engrenage externe à une dent. Le stator est un engrenage interne à deux dents. La différence d'une dent entre rotor et stator crée, par le mouvement tournant excentré du rotor, des alvéoles closes qui se meuvent parallèlement à l'axe du stator, dans un plan hélicoïdal, véhiculant ainsi le produit pompé. 2, record 1, French, - pompe%20%C3%A0%20rotor%20h%C3%A9lico%C3%AFdal%20excentr%C3%A9
