Progressive Cavity Pumping Principle

Roto Pumps is one of the leading Progressive Cavity Pumps manufacturers. Progressive Cavity Pumps are designed to efficiently transfer liquids of different compositions. These pumps can be customized while keeping in view the viscosity and chemical properties of the liquid to be transferred. These pumps work with the help of a precision mechanized single external helix metallic rotor and double internal helix elastomer stator. The Progressive Cavity Pumps carry the fluid through the cavities formed as the rotor seals tightly against the stator as it moves.

The Progressive Cavity Pumps works on the principle of displacement wherein the rotor, shaped as a single helix, rotates inside the stator. The arrangement of the rotor and stator leads to the formation of a sealing line along the axis of the rotor. Whether the conditions are static or dynamic, the sealing line continues to sustain. When the rotor starts to turn inside the stator, the liquid starts moving inside the cavities formed along the suction and discharge end of the pump.

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.
