Polymer melt pump EXTRU series

gear

Melt pumps for extrusion The extrusion gear pump is mainly used in connection with extruders or kneaders. They lower the naturally existing pulsation and uneven transportation, particularly of single-screw extruders. The extrusion pump is also used as a melt pump. It takes over the establishment of the required transport pressure, which is needed for the downstream equipment. Efficient pressure build-up In the gear pump, the pressure build-up occur significantly more efficiently than in the extruder itself. The extruder is relieved through the use of an extrusion pump. Significantly less energy or heat is added to the polymer. The melt pump thereby contributes to the gentlest possible transportation. The EXTRU pump is indispensable for the production of precise foils or micro-granulate. Robust and flexible The robust design and wear-resistant materials make the EXTRU indispensable for extrusion. It can also be used to transport natural rubber and soft PVC through different special designs. The WITTE fast-changing color design is perfect for master batch applications with frequently changing colors.
