Polymer processes in the polymer industry require units that gently discharge low and high-viscosity plastic melts from reactors and degassing equipment. The MAAG polymer extraction pump systems and viscorex® transfer gear pumps feature the excellent fill behaviour and short residence times that make them the ideal solution for such polymer applications. Their high efficiency and long service life will enhance the capacity and availability of your polymer production line. viscorex® transfer gear pumps efficiently convey plastic melts with a constant, precise flow.
Suitable for Resin & Virgin Polymer Production
Configure your own product according to your requirements and needs. If you are unsure of the configuration, provide us in the notes the necessary information about the existing sensor or product, even a competitor. We will be happy to help you find an alternative MAAG products. If your request is urgent, let us know. We will do our best to help you resolve this situation to your satisfaction as quickly as possible. If we have all the information, we are able to offer a model with minor differences.

Seal for polymer gear pumps and polymer pump systems and applications
High reliability and functionality are crucial for a seal in the polymer application discharging process for guaranteeing optimized product quality and line availability. The vispac® shaft seal is known for its robustness and reliability and especially for its easy handling. This low-maintenance seal is a proven combination of the viscoseal system and sealed packing glands for polymer pump systems.
