These pumps are of the following types: Progressive Cavity Pump, Twin Screw Pump, Gear Pump, Macerator and AODD.Roto Pumps is the market leader for the past 45 years.
These pumps operate with the help of a single external helix metallic rotor and a stator that is a double internal helix elastomer.
When the rotor rotates inside the stator, cavities are formed.
These cavities move the liquid from the suction end to the discharge end of the pump.
The Progressive Cavity Pump can perform in both directions and handle highly viscous liquids with pseudo-plastic characteristics.
Because of their single rotating element cavities are formed which ensure metered and uniform flow of liquids.
