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.
