Viking External Gear Pump | Rotary Gear Pump | IDEX India

External Gear Pump Technology:

While external gear pumps are similar to internal gear pumps, the only difference is the use of two identical gears rotating against each other — one gear is driven by a motor and it in turn drives the other gear.External gear pumps are mostly used where high pressure is required e.g hydraulic applications.

Benefits of the internal gear pump:

  • High pressure
  • Relatively high speed
  • Silent operation
  • Suitable for wide variety of materials
  • Flexible design
