Extrusion Line Synchronization Made Easy. With an 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.
The Xaloy Melt Pump is a positive displacement device which provides a linear output over a wide range of operating conditions.
A closed-loop drive control varies extruder screw speed to assure an adequate amount of polymer to the pump regardless of inlet pressure variations due to extruder surge and screw beat. Precise construction makes Xaloy Melt Pumps extremely accurate volumetric metering devices. Each gear tooth bucket carries a precise, repeatable amount of polymer melt to the output side of the pump.
Integrate the Systems
Put an Xaloy Screen Changer in front of the Xaloy Melt Pump and further increase the productivity of the extrusion line all from one company.
