Because of single rotating element, progressive cavities are generated which deliver a uniform, metered and non-pulsating flow. The head developed is independent of the rotational speed, where as the capicity is proportionate to the speed.
Self priming -
Inherently self-priming, the pumps can work on snore and do not requier foot valve.
Can handle solid in suspension or medias contaning a high percentage of solids.
Low NPSH Requirement -
Suction lift capabilities of up to 9.5mwc and
effective in high vacuum coditions.
Low Internal Velocity-
Minimum degradation of share-sensitive media, and can also handle highly viscous materials having pseudo-plastic characteristics.
Due to the reversible rotation capabilities, progressive cavity pumps can preform with equal efficiency in either direction.
Silent Running -
Rotors turn inside a resilient stator and thus generate little noise.
