Overview Introduction
Liquid Feeders
A versatile concept for the accurate feeding of liquids and pastes Coperion K-Tron’s liquid loss-in-weight feeders deliver precise, continuous volumetric or gravimetric flow control for liquids. These highly accurate gravimetric units integrate the pump and tank with either a suspension scale or platform scale; the feed pump, responsible for metering the material, is positioned outside the scale area. When handling liquid feeds, the specific requirements of each application can vary significantly. To address these needs, a wide range of pumps and tanks can be combined to create a customized Liquid Feeder solution tailored to the unique demands of the process. The feed pump is carefully selected based on both the material being handled and the required feeding capacity.

AREAS OF APPLICATION
Thanks to the wide variety of pumps and tanks available, Liquid Feeders can handle a broad range of applications. They are suitable for diverse industries, and the thousands of units already installed demonstrate their reliability in daily use—efficiently delivering pastes or liquids directly into production processes. Common bulk materials fed by this type of feeder include acids, plasticizers, molasses, and flavorings. Other applications include, for instance, feeding meat slurry into extruders during food or pet food processing, or incorporating liquid additives into polyethylene production lines.
For highly accurate dispensing of high-value liquids and pastes—such as flavors and aromatics in the food industry—gravimetric models equipped with a suspension scale or platform scale are ideal. Heated units can be provided when material viscosity poses a challenge, or for handling temperature-sensitive substances. Additionally, depending on the specific requirements of the application, complementary downstream equipment like mixers can also be supplied.

Liquid Feeder operating principle
When feeding liquids, the specific requirements of each application vary. Although based on a modular design, our Liquid Feeders are therefore always custom-built. Please contact us for more details.
Feed rates depend on the configuration.
The pump is located outside the weighing area. A flexible connecting line is required between the tank and the pump.
