The stator is made of resilient elastomeric materials and bonded to stator tubes.
A single helical rotor rolls eccentrically in double threaded helix stator of twice the pitch length
The opposing cavities fill and empty simultaneously resulting in a pulsation less flow
The liquid travels axially with relatively low velocity and minimum agitation.
FEATURES
Positive Displacement- As having a single rotating element, progressive cavities are generated and it gives a uniform and metered flow required.
Non- Clogging- It can handle solid in suspension or media having a high percentage of solids
Self Priming- can work in negative suction, so do not require a foot valve.
Silent Running- As the rotor runs inside the steady stator, so it makes a little noise. Gentle pumping action minimizes shear and crushes damage.
Reversible- As it has a reversible rotation capability; a progressive cavity pump can perform with the same efficiency in the clockwise or anti-clockwise direction.
Low NPSH Requirement- As having a suction lift capability it can perform in vacuum condition.
Separate Bearing Housing- Fluid cannot enter in the bearing housing which gives the life to bearings and easy for maintenance
Low running speeds- ideal for abrasive applications.
Stators are available in a wide range of elastomeric as per application.
Easy to dismantle and assemble without special tools.
