A rotor pump filling machine is a mechanical device used for accurately filling high-viscosity liquids. It operates by using the rotational motion of the rotor pump to draw liquid from the reservoir and, through a precise metering system, accurately distribute the liquid into containers. The design principle of the rotor pump is based on the relative movement between two or more rotors, creating a sealed space that propels the liquid flow. Due to its excellent sealing performance and precise filling control, rotor pump filling machines are widely used in the pharmaceutical, food, cosmetics, and chemical industries, especially for filling high-viscosity or particulate liquids such as pastes, syrups, and emulsions.
