Polyefin compounding pumps

Compounding processes require gear pumps that build up the pressure after the compounder for downstream equipment. Thanks to special gearings with low squeeze effect, the polyrex® gear pump from Maag is ideal for these types of application.

The high level of efficiency and long service life increase the overall efficiency of your production plant. Extensions with shaft and bearing tempering facilitate the efficient removal of heat, and consequently a tremendous increase in throughput as well as a positive impact on product quality.

Benefits
