Introduction of Pressurized melt pump
Pressurized melt pump is mainly used for extruder or pressurization, stabilizing flow and transportation of medium or high viscosity polymer. This pressurized pump adopts electric heating, and appliers to PS, PET, PVC, PC, PMMA, HDPE, LDPE, LLDPE, PP, etc.

Technical Parameter of Pressurized gear pump
◆ Melt Pump Body: High Temperature Tool Steel or Chromium-nickel Steel
◆ Gear: Stainless Steel, Nitrided Steel, or Customization
◆ Tooth profile: Straight tooth, Helical tooth, Herringbone tooth
◆ Sliding Bearing: High Temperature Tool Steel, special material and wear-resistant coating
◆ Shaft Sealing: Screw sealing, Packing seal, Screw sealing+Packing seal, the other combined sealing
◆ Heating System: Conduction oil heating

Operating Parameter of Pressurized pump
◆ Volume Range: 0.5CC - 2500CC
◆ Viscosity: ≤40000 Pas
◆ Working Temperature: ≤400°C
◆ Cleaning Temperature: ≤450°C
◆ Outlet Pressure: ≤12MPa
◆ Differential Pressure: ≤25Mpa

Advantages of Pressurized melt pump
◆ Stable output pressure, can effectively reduce the extrusion parameters caused by the unstable output of material and pressure pulsation.
◆ Improve the quality of the product dimensions and tolerances -- will minimize the extrusion products, reducewaste and scrap rate. Common extrusion machine can produce high precision products.
◆ Increase the output, reduce the pressure of the screw, the screw to die pressing, to melt pump to the die headpressure, the screw can be high speed extrusion, and can adjust the pressure to reduce the extruder, meltresidence time in screw cylinder, stable plasticizing process, reduce the melting temperature, improve the yield and quality of products.
◆ Reduce unit energy consumption, data showed that the same granulation to twin screw extruder and melt pump combination, the mixing quality and yield is greatly improved than the twin-screw granulator unit separate. Energy consumption per kilogram of materials processing can be reduced by about 1/4.
