PO PWO |  PWO-type 3-screw pumps

Description

PWO-type 3-screw pumps

  • For low viscosity lubro-refrigerant fluids, with minimum lubricating properties (minimum oil: 5%)
  • Mineral and natural oils, low-viscosity fuel fluids.
  • Flow rate up to 600 L/min
  • Admissible delivery pressure (continuous) = 100 bar at 2900 rpm
  • Standard use:
    • High pressure lubrication and cooling circuits for machine tools
    • To pump fluids with low lubricating properties in refining plants.
