熔体泵用于生产HDPE / LDPE / LLDPE。熔体泵用于HDPE / LDPE / LLDPE的生产和加工。EXTRU系列是exkat适应这些过程的要求,从而具有最高的精度。特殊的锯齿允许几乎无脉动的传送熔体,这保证了持续的高产品质量。紧凑和兼容的EXTRU III泵是紧凑的设计和印象通过他们非凡的兼容性。其轻结构和紧凑的设计允许简单的安装,从而节省时间和宝贵的地板空间。EXTRU III可以在高达30.000 Pas的粘度下操作。, températures的350°C,吸压高达120 bar,压差高达250 bar。标准的EXTRU III泵提供铝青铜粘密封。这种动态轴密封是专门为高粘度和吸入压力设计的,如果需要,可以提供冷却。 Because of the efficient build-up of pressure in comparison to extruders, the product can be conveyed in a very gentle manner with the WITTE EXTRU III gear pump, as comparatively little energy or heat is transferred to the polymer. They allow an extremely précisé and almost pulsation-free conveyance of polymer, so that fluctuations in conveyance by the extruder will be compensated for. The friction bearings are provided with spécial lubrication pockets and channels to ensure long-term, reliable operation.
