I will explain in detail the structural differences between external gear pumps and internal gear pumps!
I will introduce the structure of gear pumps. The "external gear pump" has a small outer diameter and a long width, and it rotates on two axes, allowing for an increase in peripheral speed. On the other hand, the "internal gear pump" has a large outer diameter and a narrow width, and it rotates on a single axis, making it difficult to increase peripheral speed. When set to 0.2L/rev, there are differences related to the size of the pump.

Overview of External Gear Pumps ■ Inside the casing, there are two gears that mesh together: the driving gear and the driven gear, rotating while maintaining clearance. ■ As the gears rotate, the liquid moves along the inside of the casing towards the discharge side. ■ By changing the rotation speed, it is possible to vary the flow rate as desired. *For more details, please refer to the PDF document or feel free to contact us.*
