Positive Displacement– 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 capacity is proportionate to the speed.

Self Priming – Inherently self-priming, the pumps can work on snore and do not require foot valve.

Non-Clogging – Can handle solid in suspension or medias containing a high percentage of solids.

Low NPSH Requirement – Suction lift capabilities of up to 9.5mwc and effective in high vacuum conditions.

Low Internal Velocity– Minimum degradation of share-sensitive media, and can also handle highly viscous materials having pseudo-plastic characteristics.

Reversible– 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.

Separate Bearing Housing – Fluids can be pumped without no contamination.
