Internal gear pumps have many uses. Although they are commonly used for thin liquids (such as solvents and fuel oils), they are good at efficiently pumping thicker liquids such as asphalt, chocolate, and binders. The useful viscosity range of internal gear pumps is 1cPs to more than 1,000,000cP.
In addition to its wide viscosity range, the pump also has a wide temperature range and can handle liquids up to 750°F/400°C. This is due to a single point of end clearance (the distance between the end of the rotor gear teeth and the pump head). The gap is adjustable to adapt to high temperatures, maximize the efficiency of handling high-viscosity liquids and adapt to wear.
Rotor and idler. The internal gear pump is pulse-free, self-priming, and can be idling for a short time. They also rotate in both directions, which means that the same pump can be used to load and unload containers. Since the internal gear pump has only two moving parts, they are reliable, easy to operate and easy to maintain.
