Extrusion operations require extremely reliable gear pump systems with high output consistency and a configuration to suit each application. The modular design of extrex® gear pumps easily meet the requirements for these diverse applications. The extrex6 EC gear pump is generally designed for PVC applications. The new pump design is optimized to the needs of processing PVC. All pumps are equipped with ST design (flow optimized). In addition, the process temperature is controlled by an innovative shaft cooling solution.
