High Pressure Melt Pumps

Extrusion Line Synchronization Made Easy. With an MICRO TURN 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 additional control of a MICRO TURN 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 MICRO TURN 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.

The MICRO TURN 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 MICRO TURN Melt Pumps extremely accurate volumetric metering devices. Each gear tooth Aca A bucketAca A carries a precise, repeatable amount of polymer melt to the output side of the pump.
