Polymer Melt Gear Pump for 5 Layer Sheet Co-Extrusion Line

Polymer melt pump for plastic sheet extrusion line 

Melt pumps come in a variety of types and sizes to fit the needs of your extrusion, compounding or polymer production process.



Benifits of the metering pump melt gear pump
1. Stabilizing the output pressure---the pressure on extruder can be reduced by 30%-50% after using melt pumps.
2. improving the product quality
3. increasing the extrusion output---reducing pressure on screw and chaning the building pressure from "screw to die" to "melt pump to die", so the screw can extrude the products with high efficiency. Mean while the back-pressure on the extruder can be adjusted, reducing the melt residence in screw cylinder, stabilizing the plasticizing process and improving the product's quality and quantity.
4. prolonging the working life---the pressure of extruder screw can be lowered after using the melt pumps, so screw wear can be reduced consumable
