Internal Gear Pumps

Working Principle

The Internal gear pump employs proven Internal gearing (Gear within gear) principle for pumping. As the gears come out of mesh, a partial vacuum is created, forcing the fluid to rush into the pump casing and fill in voids between teeth. Both gears rotating in the same direction of rotation gently transfer the fluid to the delivery port.

Benefits

  • Smooth quite flow
  • Excellent self priming
  • Insensitive to viscosities
  • Single sealing, external bearing
  • Low noise and pulsation
  • Reversibility
  • Easy maintenance

Applications

  • Loading, unloading, transfer, circulation and process pumping of a very wide range of products typically as thin as diesel oil to extremely high viscous substances
  • Unloading of tank lorries and rail car
  • Loading of rail cars, tank lorries and barrel filling
