The APS-P4 Centrifugal Screw Pump is ideal for pumping high viscosity liquids such as crude oils, latex, molasses, and refinery wastes using a positive displacement screw.  When pumping lighter materials, the impeller acts as a centrifugal type providing high capacity.


  • Unique centrifugal screw impeller allows pumping of liquids with viscosities to 10,000 CST
  • Small overall size allows for use in confined places
  • Oil lubricated seals (can run dry)
  • Variable speed hydraulic drive
  • Wide range performance
  • Safe hydraulic drive can be used where electric power is hazardous or impractical
  • Will pass 2" semi-solids
  • Can be used in -line as a booster pumps
