Gear pumps for compounding - Pump Solutions Group

GEAR PUMPS
Process-orientated and efficient
Gentle handling of the melt is essential for an optimal process.
Supply pumps, reactor discharge pumps, and booster
pumps are required for both low-viscosity and high-viscosity
media. Such pumps considerably boost pro ductivity,
quality, and operating reliability in polymer production.
Gear pumps made by Maag Pump Systems meet even
highest requirements and supply the particular media with
an outstanding consistency and precision.
The production and the processing of oligomers as well as
of polymers require permanent and steady melt supply.
For polymer production, optimized flow channel geometry
enables the melt to exit the vacuum. In general,
polymer-related processes require devices which are capable
of gently discharging both low-viscosity and highviscosity
plastic melts from reactors and of degasing installations.
For this purpose, the vacorex ® , viscorex ® , and
thermorex ® gear pumps made by Maag are available
featuring special sealing systems such as vispac ® or viscoseal
to further increase operating reliability. The polyrex ®
pumps are mainly applied in compounding systems as
such pumps allow high throughput rates due to their special
shaft and bearing designs. The retrofit shaft and bearing
tempering system allows an additional significant raise
in throughput.
