Understanding Internal Gear Pumps

Internal gear pumps utilize a pair of gears to move fluids. As one gear turns, it creates a void that draws liquid in through an inlet port. The liquid is then trapped between the gears and forced out through an outlet. This design allows for smooth, continuous flow and precise metering, making internal gear pumps ideal for handling viscous liquids.

Why Choose Internal Gear Pumps?

These pumps come with several benefits, including:

  • High Efficiency: Internal gear pumps are designed to minimize energy loss while moving fluids.
  • Versatility: They can handle a wide range of viscosities and can pump various types of liquids, from water-like fluids to heavier oils.
  • Durability: With fewer moving parts than some other pump types, internal gear pumps tend to show lower wear over time.
