Standard Melt Pumps (MSDP) Signi cant Material Savings igher Product Less Scrap and uns egrind educe Load on Your Extruder Extrusion Line Synchronization Made Easy. With an Nordson XALOY pump between your extruder and die you can directly dial in gauge control, eliminating extruder surge and 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. A melt pump, while not a mixing or melting device, is extremely efficient at building pressure and metering the polymer output. Additives Pellet Regrind The additional control of a Nordson XALOY Melt Pump installation also provides you with more production line flexibility, first by shortening start-up times on difficult materials and second, by processing multiple polymers with the same screw. The Nordson XALOY EMPAC Control closes the loop from pump inlet pressure to extruder drive while monitoring downstream pressure to eliminate any problems due to downstream line stoppage.

Standard Melt Pumps (MSDP) MSDP MSDP MSDP MSDP MSDP MSDP MSDP MSDP PCP PCP PCP PCP PCP Maximum Operating Pressure: 5,000 psig (345 BAR) Maximum Differential Pressure: 4,000 psig (276 BAR) Transducer Ports: 4 locations in body for 155 size and larger pumps Note: The MJEP model is an option for both the MSDP and PCP models. The pump body has internal channels to accept a heat/cool fluid media. The MJEP option is utilized for heat sensitive polymers when very accurate temperature regulation is required.
