  • Crude oil & oil products 
  • Lubricating oil 
  • Fresh water & oily water 
  • Sea water, bilge & ballast 
  • Aircraft refueling & aviation fuels 
  • Bitumen & asphalt 
  • Fire foam concentrate & boiler firing 

Industrial Usage 

  • Industrial, oil exploration & petrochemical environments 
  • Viscous fuel for Storage plant
  • Marine, offshore & dock areas

Design & Special Features 

  • Horizontal / Vertical twin screw types 
  • API 676 standard
  • Horizontal model heating options available
  • Space-saving vertical models 
  • Vertical models available with or without integral relief valve 
  • Pumps fitted with hardened timing gears and locating bearings  so there is no contact between the screws
  • Shaft stiffness maximized by the screw design hydraulic balance 
  • Maximum volumetric efficiency
  • Excellent suction lift 
  • NPSH required is dependant on viscosity and speed, and can be as low as 0.5m 
  • Fully guaranteed 
  • Maintenance can normally be carried out without disconnecting either the suction or delivery pipe work and with the electric motor remaining situ
