Roto Pumps is one of the principal Progressive Cavity Pumps manufacturers. These PC pumps function with the help of rotor and a stator. The liquid starts to get suctioned inside the pump when the precision mechanized single helix metallic rotor rotates inside the double internal helix elastomer stator. Along with the circulation of the rotor, cavities gets formed between the rotor and the walls of the stator. The rotor pulls the liquid inside the pump, which moves along its axis through the cavities formed between the rotor and the stator, and gets discharged from the discharge end of the pump. These PC pumps offers high low life cycle cost, are non-clogging and provide smooth and non-pulsating flow.
Progressive Cavity Pumps are used in several industries such as paint, varnish and ink, mining and chemicals etc. These pumps can be customized to handle a wide variety of liquids with different chemical properties and compositions. These PC pumps are the first choice for a number of customers as they can easily be customized to suit their specific needs and requirements.
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.
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.
