EXTRU - Melt pump for extrusion and pressure increase of medium to high viscosity media.
The extrusion gear pump is mainly used in combination with extruders or kneaders. It reduces the natural pulsation of the extruder and compensates for fluctuations in delivery, especially in single screw extruders. The extrusion pump is used as a melt pump. It builds up the required feed pressure, which is needed for the downstream die. The pressure build-up in the gear pump can be much more efficient than in the extruder itself. The extruder is relieved by using an extrusion pump. Furthermore, considerably less energy or heat is introduced into the polymer. The melt pump thus contributes to conveying the product as gently as possible. The EXTRU is indispensable for the production of precise films or micro pellets.
