Idex Explores The Beauty Of Internal Gear Pumps

According to the method of displacement pumps are categorized into positive displacement pumps and centrifugal pumps. A positive displacement pump traps a fixed amount and forces the trapped volume into discharge pipe

Internal gear pump consists of a rotor ad idler. Liquid travels between them through “gear-within-a-gear” principle. Pump head forces the liquid to move out of discharge port. A seal is formed between the discharge and suction ports. This pushes liquid out of the discharge port.

Benefits of the internal gear pump:

  • Easy on maintenance with two moving parts and one stuffing part.
  • Works well for high viscosity liquids
  • Constant flow and is not affected by pressure
  • Operates well bidirectionally
  • NPSH requirements are quite low as compared to other pumps

Typical application areas for these pumps include:

  • Fuels And Lube Oils

  • Alcohols And Solvents

  • Asphalt, Bitumen, Tar

  • Resins And Polymers, Pu Foam

  • Food Industry (chocolate, Starch)

  • Inks, Pigments, Paints

  • Soaps And Surfactants

  • Glycol

  • Base Oil, Additives etc
