Features

• Single rotating element, progressing cavities are generated which deliver a uniform, metered & non-pulsating flow.
• Head developed is independent of the rotational speed, where as the capacity is proportionate to the speed.
• Inherently self-priming, the pumps can work on snore & do not require a foot valve.
• Can Handle solids in suspension or medias containing a high percentage of solids.
• Suction lift capabilities of up to 9.5 mtr. and effective even in high vacuum conditions.
• Minimum degradation of shear-sensitive media & can also Handle highly viscous materials having pseudo-plastic characteristics.
• Due to the reversible rotation capabilities, progressive cavity pumps can perform with equal efficiency in either direction.
• Rotors turn inside a resilient stator & thus generate little noise.

Stator:

• Natural, Nitrile, High Nitrile, EPDM, Chloro-sulphonated Rubber, Fluoroelastomer

Rotor:

• Case hardened steel, alloy steel, HCP, stainless steel, up / HCP
