1,For extrusion 2,Various types 3,Nearly suitable for all the raw materials 4,Excellent wear resistance 5.Reasonable price Various melt pumps find extensive applications in metering and boosting of high/low viscosity media.The housing is made of Chrome-nickel alloy or nickel-based alloys, tantalum alloys.Gears are made of quenched chrome-steel or other similar metals, which is efficient and leakproof.Bearings are made of Graphite, NIAG, zirconia or quenched tool steel.Come with frequency conversion motor and reducer to vary the speed, contributing to higher consistency in die pressure and better production quality.Applicable materials: PC, PMMA, ABS, PET, PVB, PS, PP, PE, etc.The melt pump can adjust and control the amount of extruder through the feedback by the pressure sensor, so it will make certain that  the materials can output evenly.
