High Pressure Melt Pumps (MHDP)• Significant Material Savings• Higher Product Quality• Less Scrap and Runs Regrind• Reduce Load on Your ExtruderThe additional control of a XaloyMelt Pump installation also providesyou with more production line flexibility,first by shortening start-uptimes on difficult materials andsecond, by processing multiplepolymers with the same screw.The Xaloy EMPAC Control closesthe loop from pump inlet pressureto extruder drive while monitoringdownstream pressure to eliminateany problems due to downstreamline stoppage.Benefits• Material Savings• Increased Output• Increased Extruder Life• Faster Start Ups• Lower Processing Temperature• More Accurate Gauge Control• Reduced Scrap• Lower Shear Stress• Process Recycled Materials• Fast Paybacks• Sizes Available for allProducts/ExtrudersExtrusion Line Synchronization Made Easy. With an Xaloy pump between yourextruder and die you can directly dial in gauge control, eliminating extruder surgeand screw beat at the die. Extruder screws efficiently melt, mix and convey polymer,but are not as efficient at providing a consistent pressure and volume to the die. Amelt pump, while not a mixing or melting device, is extremely efficient at buildingpressure and metering the polymer output.S/C Manual or Hydarulic Screen ChangerP Melt PumpS/M Static MixerPID Signalto maintaininlet pressureto pumpThe Xaloy Melt Pump is apositive displacement devicewhich provides a linearoutput over a wide range ofoperating conditions.A closed-loop drive control variesextruder screw speed to assure anadequate amount of polymer to thepump regardless of inlet pressurevariations due to extruder surgeand screw beat.
