ROTO - Progressive Cavity Pump
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.
- Positive displacement pump discharge sizes:
- Because of the single rotating element, progressing cavities are generated which deliver a uniform, metered & non-pulsating flow. The head developed is independent of the rotational speed, whereas the capacity is proportionate to the speed.
- Housing:
- SEPARATE BEARING 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:
- Minimum degradation of shear-sensitive media, and can also handle highly viscous materials having pseudo- plastic characteristics.
- Reversible :
- Due to the reversible rotation capabilities, progressive cavity pumps can perform with equal efficiency in either direction.
- Silent Running:
- Rotors turn inside a resilient stator & thus generate little noise.
