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
the fluid.
| Housing | |
|---|---|
| Self-Priming | Inherently self-priming, the pumps can work on snore & do not require a foot valve. |
| Non-Clogging | Can handle solids in suspension or medias containing a high percentage of solids. |
| Low NPSH Requirement | Suction lift capabilities of up to 9.5 mwc & effective even in high vacuum conditions. |
| Low Internal Velocity | |
| Reversible | |
| Silent Running | Rotors turn inside a resilient stator & thus generate little noise. |
