Melt pumps for extrusion, compounding and polymerization. The gear pump cannot be neglected in the extrusion if you want to produce high-quality products. Despite of its simple and robust design, it is a high-precision displacement pump and convinces by its conveyance accuracy and its capacity in pressure build-up at minimum thermal material strain. Whereas the gear pump maintains a constant volumetric output and the required pressure at the tool, the pressure at the outlet of the extruder can be set to an optimal duty point.
