HELICAL ROTOR PUMPS / PROGRESSIVE CAVITY PUMP

Helical Rotor Pumps / Progressive Cavity Pump

A helical rotor pump works by the rotation of a helical rotor pushing discrete quantities of liquids through the pump. The pumps are suitable for pumping viscous materials and fluid metering, as well as chemical processing, resins and adhesives.

Features of the helical rotor pump includes:

  • product not influenced during pumping process
  • accurate volumetric
  • reversible flow direction
  • valve-less operation
  • self-priming
  • constant non-pulsating flow
  • can handle abrasive and highly viscous fluids
 

WORKING PRINCIPLE

Helical rotor pumps have a long tubular profile and contain a single rotor with a screw-shaped rotating element. This is held with a moulded stator - typically constructed from rubber or some other tough polymer.

A positive displacement action draws the fluid into the stator, and the rotor applies radial motion. The engine or motor provides the required rotational energy.

An inlet port and outlet bookend the rotor and deliver the fluid within churning or damaging the material.

PRODUCT INFORMATION

Global Pumps offer a variety of Helical Rotor Pumps with the following features:

The helical rotor pumps offers precision machines single external helix metallic rotor, and a double internal helix elastomer stator. They offer a smarter shaft sealing, tough bearings, improved pump housing and tapered entry stator. The helical rotor pump offers operators the following benefits: self-priming, non-clogging, low NPSH requirement, low internal velocity, silent running and separate bearing housing.

They also offer reduced thrust loads on bearing and universal joins, ensuring an increasing service life. As well as smooth and even performance, reduced vibration, turbulence, shear rates and pulsation, lower sliding velocity, lengthy pitch and lengthy geometry.

The range of helical rotor pumps offer the following for operators:

  • viscosities up to 30,000 cst
  • can handle temperatures up to 150oC
  • solid handling up to 7%
  • discharge pressure up to 48 bar (341 PSI)
  • capacity: up to 345 m3/hr
  • head up to 500 m3/hr
  • available in a variety of constructions including cast iron, with rotating parts in alloy steel, tool steel, SS 304 and SS 316
