The introduction of processes such as foaming and co-extrusion to drive down costs in the production of pipe and profiles often involves the use of multiple die assemblies. Complex set-ups such as these require very high pressure levels and constant throughput rates during extrusion which in turn increase expectations relative to the pumps involved in the process.
Maag's twin outlet extrex GPD gear pump sets itself apart since it allows producers to use only one extruder to feed two die assemblies with a constant flow. Thanks to a combination of a single inlet and two outlets, an extrusion line fitted with this pump will be capable of running two completely different die head assemblies with distinct throughput and pressure ratings to produce high quality products.
This innovative pump features a novel design geometry delivering a higher degree of effectiveness for the producer of semi-finished extrusion goods. The pump’s reliability, optimized design, improved sealing capabilities and temperature distribution guarantees product homogeneity.
Recognizing the need for process-oriented customization, the company offers a range of heating options, including the choice of electric or fluid media. Special pump configurations meant to answer specific customer requirements are also offered as an optional service. The pump is available for new installations but can also be ordered as a retrofit.
