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
