Extruders - Import export

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.

Melt pump specially designed for use in the production of medical tubing made of TPE, PE or PA. The melt pump is installed downstream of the extruder in the extrusion process for pressure build-up and constant delivery of the melt to the die. It is particularly important for medical tubing that the wall thickness and quality is absolutely constant and uniform.
