Gear pump for screw extruder

Gear pump for screw extruder dedicated to thermoplastic melt pump extrusion process requires special stable extrusion pressure flow system, installed on the extruder between exports and die head for metering pump.
Gear Pump For Screw Extruder Advantages:
1. The pressure on extruder can be reduced by 30%-50% with the melt pump.
2. Improving the product quality.
3. Increasing the extrusion output. The screw can extrude the products with high efficiency. 
4. The back-pressure on the extruder can be adjusted, reducing the melt residence in screw cylinder, stabilizing the plasticizing process.
4. The pressure of extruder screw can be lowered after using melt pump extrusion, so screw wear can be reduced consumable.
Gear Pump For Screw Extruder Applications: 
1. Polymer extrusion molding, such as granulation, film, pipe, plate, sheet, etc;
2. High viscosity materials such as PC, PMMA, ABS, HIPS, PET, PVB, PS, PP, PA, PE, PVA .etc;
3. Rubber, asphalt, paint, adhesives, coatings, lubricants, polyalcohol, non-particulate impurities;
4. Polyester for cotton-fiber, polypropylene and other chemical fiber melt.
