GEAR PUMP

A type of positive displacement pump that moves fluid using rotating gears. The fluid is transferred through the process of trapping the fluid between the gear teeth and the casing, then flows from the inlet to the outlet due to the rotation of the gear. Gear pumps are renowned for their ability to pump high viscosity fluids while providing steady flow and constant pressure.

Types of Gear Pumps

External Gear Pump (External Gear Pump):

  • Configuration: Consists of two interlocking gears in the casing.
  • Characteristics: High efficiency, suitable for fluids with low to high viscosity, and produces high pressure.
  • Application: Fuel, lubricating oil and hydraulic applications.

Internal Gear Pump:

  • Configuration: Has one internal gear that interacts with an external gear in the casing.
  • Characteristics: More compact design, handles very high viscosity fluids, quieter operation, and produces minimal flow pulsation.
  • Applications: Food liquids, syrups, chemicals and heavy oils.

Crescent Gear Pump (Lobe Gear Pump):

  • Configuration: Uses two crescent-shaped rotors that rotate in the casing.
  • Characteristics: Larger flow capacity, able to handle particles in liquids, and suitable for high viscosity liquids.
  • Applications: Food processing, pharmaceuticals and cosmetics.
