(ZP) Combination of Extruder and Gearpump

In combination with a GS, QSM or vacuum extruder, the gear pump enhances the Troester extruder and allows it to work at the highest levels of accuracy and quality.

The compound is plastified in the extruder and fed into the gear pump under low intake pressure. The gear pump’s intake pressure regulates the speed of the extruder so that the gear pump is always completely filled. A screen can be located in front of the gear pump if needed to filter out foreign objects and can thus replace any strainer needed in production before the extruder head.

The combination of extruder and gear pump is thus advantageous in the case of particularly difficult process requirements. These can include maintaining the lowest output variations and product dimension tolerances, and avoiding flooding the vacuum zone as well as avoiding poor output-temperature relationships at high die pressure.
