Progressive Cavity Pumps, High Pressure Progressive Cavity Pump Manufacturers

Progressive Cavity Pumps are widely used pumps in a number of industries as they can handle a variety of fluids of varied compositions. The industries that actively use these kinds of pumps in their day-to-day working include paper, sugar, waste water, paint, chemical, oil and gas etc. Each of these pumps can be customized and designed as per the respective needs of the customers, like the chemical properties and the viscosity of the liquids to be transferred.

Progressive Capacity Pumps operate on the principle of positive displacement. These pumps comprise of a precision mechanized single external helix metallic rotor that is located inside a double internal helix elastomer stator. When the rotor starts to rotate inside the stator, cavities gets formed. The liquid gets pumped in from the suction end of the pump, and is carried along the spindle of the stator through the formed cavities towards the discharge end of the pump.

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.

Non-Clogging
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.

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 and thus generate little noise.

Separate Bearing Housing
Fluids can be pumped without no contamination.
