PP line’s upgrade improves efficiency, quality

An Asian supplier of polypropylene (PP) opted for an upgrade to its screen changer and melt pump and realized via this retrofitting a considerable boost in output and product quality.

An Asian supplier of polypropylene (PP) opted for an upgrade to its screen changer and melt pump and realized via this retrofitting a considerable boost in output and product quality.


The Asian supplier opted for this Kreyenborg melt pump plus screen changer.


The unidentified supplier opted for its retrofit for a completely new discharge unit from Kreyenborg (Münster, Germany), with the new piston screen changer and a melt pump replacing the established melt filter. The retrofitting had two primary goals:  increase throughput capacity of the whole line and increase filter fineness.

The filter area was increased by the replacement of the old slide plate screen changer by a continuous piston screen changer from Kreyenborg, type LK-SWE. Combining this with the new melt pump raised throughput to 9000 kg/hour. Additionally, the piston screen changer allows for continuous operation of the line, as it need not be stopped for changes of the filter media.

The new melt pump provided a sufficient increase in pressure to ensure a higher filter fineness can be achieved. [email protected]
