Progressive Cavity Pumping Principle
The pumping element comprises of a precision machined single external helix metallic rotor and a double internal helix elastomer stator. Due to special profile of Rotor and Stator, a sealing line is formed along the axis of the rotor, which is maintained at static or dynamic condition. As the rotor turns within the stator, these cavities progress from suction to discharge end of the pump carrying the fluid.
Distinctive design features & benefits :

• POSITIVE DISPLACEMENT : Head developed is independent of speed whereas capacity is proportionate to speed. Delivers Uniform, metered and Non Pulsating Flow.
• SELF-PRIMING : Inherently self-priming, can work on snore and does not require foot valve
• NON-CLOGGING : Handles solids in suspension or mixture containing high percentage of solids.
• LOW NPSH REQUIREMENT : Suction lift capability up to 9.5 mwc and effective even in high vacuum conditions.
• LOW INTERNAL VELOCITY : Minimum degradation of shear sensitive media
• REVERSIBLE : Provides flexibility in operation
