How a Progressing Cavity Pump Works

  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.


Uncompromising Quality Design and Materials of Construction

Highest Grade Components

1.       Abrasion-resistant chrome-plated rotors in high grade carbon steel or 316 stainless. New Ultra-Shield rotor coatings are available on all models.

2.       Wide variety of Ultra-Flex stator elastomers to meet specific application needs.

3.       Wettable pump body parts in cast iron or 316 stainless.

Versatile Piping Connections

4.       Flanges available in 12kg/cm2 or 24kg/ cm.flat face, cast iron or stainless steel on pump suction and discharge ends

50kg/ cm2 .raised face flanges on discharge end of four-stage,high-pressure pumps.

5.       Suction port can be rotated to four positions,90? apart.

Open throat with large suction hopper allows smooth flow of viscous materials from auger assembly to rotor/stator elements.


Easy Assembly and Disassembly

6.       Only standard tools needed for repairs.

7.       Drain plug allows easy, complete drainage of suction housing for pump inspection or maintenance.


Low-Maintenance Drive Trains
