Ques: What is the Principle behind a progressive cavity pump?

Answer :Progressive Cavity Pumps which are also commonly known as Eccentric Screw Pumps / Helical Rotor Pumps / PC Pumps.The main component which characterize these pumps are a metallic single helical rotary part ROTOR and a fixed double helical resilient Polymer part STATOR in which the rotor turns and thereby a complex progressive sealing  line is maintained. Whilst the rotor rotates inside the stator, the cavities formed between them progresses from suction to discharge end gently carrying the media.
