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 the special profile of the rotor and
stator set, a sealing line is formed along the axis of the rotor
which is maintained at both static and dynamic conditions.
As the rotor turns within the stator, these cavities progress
from the suction to the discharge end of the pump carrying
