Helical Rotor Pumps 

Helical Rotor Pumps

Helical rotor pumps, also known as progressive cavity pumps or cavity pumps, are a type of rotary positive displacement pump that has a single threaded helically shaped rotor turning inside of a double-threaded helically shaped rubber stator. This produces a progressing cavity that moves the liquid through the pump and creates the pumping action.

Helical rotor pumps are used extensively in sewerage and water treatment plants to pump polymer, sludge and chemicals. They are also used in all types of industrial applications for pumping a wide variety of thin and thick liquids, including corrosive liquids and liquids containing solids.

As progressive cavity pumps can handle difficult, thick and solid laden liquids, they can often be used in applications where no other pump would perform.

Allied Pumps carries brands such as Roto Pumps and offers a wide range of helical rotor pumps and spare parts, and has experience and expertise in hundreds of different applications of this type of pump.

  • Roto Helical Rotor Pumps

    Roto Helical Rotor Pumps cater for a wide spectrum of pumping applications, including fluid metering and pumping of highly viscous, abrasive or sheer sensitive liquids.

    Roto Helical Rotor Pumps effectively deliver non-pulsating and uniform flow, whilst maintaining a gentle pumping action. The tapered entry stator enables easy fluid entry and facilitates high suction lift capabilities.

    Optimised rotor stator geometry minimises wear from abrasive applications, achieves zero leakage, resulting in non-clogging, an extended service life and a reduction in power consumption, setting it apart from its conventional counterparts.
