An external gear pump is a positive displacement pump designed to move fluids by using two meshing gears. It is valued for its simple construction, steady fluid transfer, and ability to work across many industrial duties. The right pump depends on the fluid, pressure, viscosity, temperature, and required flow rate. Understanding these factors helps engineers choose a […]

Internal Gear Pump vs External Gear Pump: Which Should You Choose?
Choosing the right positive displacement pump depends on the fluid, pressure, viscosity, temperature, and duty cycle. Two common options are internal and external gear pumps. Both use rotating gears to move fluid, but their construction and operating methods are different. Understanding these differences helps engineers select a pump that matches the process. An internal gear pump can be […]
