Progressive Cavity Pumps And Twin Screw Pumps.
ROTO PUMPS
Roto Pumps product line comprises of Progressive Cavity Pumps and Twin Screw Pumps to meet most varied pumping requirements.
While Progressive Cavity Pumps have applications in fluid metering and pumping of highly viscous, abrasive or sheer sensitive materials, the Twin Screw Pumps are used for clean, lubricating, non-lubricating as well as aggressive liquids.
Pump Tough To Handle Fluids With Ease.
PROGRESSIVE CAVITY PUMPS
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.
Various Benefits.
FEATURES AND BENEFITS
-
Positive Displacement, because of single rotating element, progressive cavities are generated which deliver a uniform, metered and non-pulsating flow. The head developed 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 foot valve.
-
Silent Running , rotors turn inside a resilient stator and thus generate little noise.
-
Separate Bearing, housing Fluids can be pumped without any contamination.
-
Low Internal, velocity Minimum degradation of share-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.
-
Non-Clogging , can handle solid in suspension or Medias containing a high percentage of solids.
-
Low NPSH, requirement Suction lift capabilities of up to 9.5mwc and effective in high vacuum conditions.
