Although the geometry of its pumping elements may seem somewhat complex, the principle of progressing cavity pump operation is deceptively simple.
The key components are the rotor and stator The rotor is a single external helix with a round cross-section, precision machined from high-strength steel. The stator is a double internal helix molded of tough, abrasion-resistant.
elastomer, permanently bonded within an alloy steel tube. As the rotor turns within the stator, cavities are formed which progress from the suction to the discharge end of the pump, conveying the pumped material. The continuous seal between the rotor and the stator helices keeps the fluid moving steadily at a fixed flow rate proportional to the pump's rotational speed.
