Polymer processing Pumps & filtration Pelletizing Pulverizing Recycling

What MAAG addresses in practice

In modern polymer operations, it is essential to maintain a stable process, consistent quality, and the ability to respond quickly to changes in material and production conditions. MAAG builds on a “masterly overview” – broad expertise across the process steps that enables the company to design solutions “from a single source” and align components into a fully integrated system.

Typical solutions combine gear pumps (flow/pressure stabilization), melt filtration (contaminant removal and process stability), pelletizing systems (various pellet shapes and types), and, depending on the application, also pulverizing and recycling solutions.

The Group is represented in the market by a portfolio of brands: AMN, AUTOMATIK, ETTLINGER, GALA, MAAG, REDUCTION, SCHEER, WITTE, XANTEC.

  • More stable processes and quality through alignment of pumps, filtration, and downstream technologies
  • Higher throughput and efficiency thanks to systems engineered as an integrated whole
  • Support across the equipment lifecycle – service, spare parts, upgrades, training

Portfolio: systems and solutions for polymer processes

MAAG Group provides integrated solutions for the polymer, chemical, petrochemical, pharmaceutical, and food industries. The core portfolio includes gear pumps, filtration systems, pelletizers, dryers, pulverizers, and recycling systems. The emphasis is on quality, performance, and worldwide service support.

Pumps & filtration

Solutions for stable and reliable polymer processing, including demanding operating conditions. Gear pumps are typically used to stabilize the process, while filtration systems / screen changers help maintain melt quality and protect downstream equipment.

Pelletizing, pulverizing, recycling

Pelletizing technologies for various output requirements (pellet shape/size depending on the process), as well as technologies for powder production and recycling solutions where operational reliability and stable output are critical (supported by robust service capabilities).

Services and technical support

MAAG follows a “holistic” service approach: fast availability of genuine spare parts, regular inspections and maintenance, repairs, modernization and upgrades, operator training, and a service network (e.g., rotor sharpening centers). The objective is to keep machines productive and state-of-the-art throughout their service life.
