Advantages of internal gear pump The internal gear pumps conveys liquid smoothly, without pulsation, low vibration and low noise. Internal gear pump has strong self-priming performance. The internal gear pump selects the correct parts and materials, can transport a variety of corrosive media, and the use temperature can reach 200℃. Internal gear pump internal and external rotors have the same rotation direction, with little wear and long service life. The rotational speed of the internal gear pump has a linear function relationship with the flow, and the flow of the pump can be changed by changing the rotational speed appropriately. Internal gear pump is especially suitable for the transportation of high viscosity media.
