Twin Screw Pumps

Working Principle

  • The Houttuin double entry twin geared screw pump is a self priming, rotary positive displacement pump
  • Two Screw Pumps utilizes two intermeshing screws synchronized by a set of external timing gears, which are assembled into a close fit figure-eight-shaped housing
  • Flow splits to each end of pump and is transferred to a center discharge port via cavities formed by screw threads and housing
  • Symmetry of double-ended pump provides axial hydraulic balance of rotors.
  • Timing Gears and bearings maintain clearances between screw flanks
  • Pumps operate at a wide range of speeds while dealing with conventional and unconventional fluids with properties like ultra-low and ultra-high viscosity, gas entrainment, contamination and corrosives
