One of the most dynamic designs for driving the flow of variety of liquids, Progressive Cavity Pumps can be customized to efficiently handle liquids with different viscosity levels and chemical properties. The Progressive Cavity Pumps comprise of a precision mechanized single external helix metallic rotor and double internal helix elastomer stator. As the rotor turns within stators, the cavity progresses from suction to discharge along with fluid.

Pumping Principle

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.

Features & Benefits

Positive Displacement
Because of single rotating element, progressive cavities are generated which deliver a uniform, metered and non-pulsating flow. The developed head 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 a foot valve.

Can handle solid in suspension or media 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 shear-sensitive media, and 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.

Silent Running
Rotors turn inside a resilient stator and thus generate little noise.

Separate Bearing Housing
Fluids can be pumped without no contamination.
