  • Food: Chocolate, cacao butter, fillers, sugar, vegetable fats and oils, molasses, animal food etc.
  • Aviation: Jet engine fuel pumps

Efficiency :
Gear pumps are generally very efficient, especially in high-pressure applications.
Factors affecting efficiency:
– Clearances: Geometric clearances at the end and outer diameter of the gears allows leakage and back flow. However sometimes higher clearances help reduce hydrodynamic friction and improve efficiency.
– Gear backlash : High backlash between gears also allows fluid leakage. However, this helps to reduce wasted energy from trapping the fluid between gear teeth
