Concrete Sludge Mono Single Screw Pump

Single screw pumps are a type of progressive cavity pump, known for their efficient and smooth operation. They consist of a single external helix rotor and a double internal helix stator. As the metallic rotor rotates within the elastomer stator, it creates a series of continuous cavities that move axially, allowing fluid to be transported from the suction to the discharge end without turbulence or pulsation.

Features & Characteristics

  • High wear resistance and elastic materials allow the pump to handle various liquids with solid particles or fiber substances.
  • Completely separate suction and discharge chambers via spiral sealing lines, enabling the pump to function as a shut-off valve.
  • Inherent self-priming capability ensures a significant suction lift up to 8.5 meters.
  • Consistent cavity volume ensures a steady, non-pulsating flow.
  • Flow rate is proportional to speed, making it easy to control using a speed governor.

Pumped Medium

  • Liquids with different viscosities, especially high-viscosity fluids that are hard to pump.
  • Liquids with varying densities and dewatered dry materials.
  • Liquids containing solid particles, fibers, or suspended matter.
  • Mixtures of liquid, gas, and solid.
  • Shear-sensitive liquids.
  • Corrosive liquids.
