Melt pumps for the plastic extrusion machinery

Gear pumps for plastic manufacturing

The plastics industry is one of the motors of the economy. Whether packaging for food or components for the automobile industry, plastic is omnipresent today. New formulas increase the capacity and expand the areas of application for this material.

The variety of materials and manufacturing processes grows continually and present component suppliers with new requirements. In nearly any polymer production process, gear pumps are used to move the polymer in the plants and to transport it to the individual process stages. The viscous melts present very special requirements for pumps. Due to viscosity and process parameters, high-capacity, powerful and robust pumps are used to transport polymer melts.

WITTE gear pumps are used, for example, in procedures to produce thermoplastic elastomers such as TPE or TPU, polyamide or polyester.
