Applications
The products and systems of the Maag Group have been designed closely to match the requirements and applications of our customers. For this reason, the Group is organised into four business units, which serve the individual needs of our customers in line with market trends:
- Polymers
- Extrusion
- Rubber
- Industry
The Polymer unit encompasses the whole domain of plastics manufacturing and processing in which pellets, an interim product, are produced. Pellets are an important precursor in the plastics industry. During the production process, the polymer is manufactured in the form of melt or powder, which is not suitable for further processing. Various pelletising methods create particles of an even shape and size, allowing dosing, mixing, transport and melting to be made considerably easier. The polymer's properties are "frozen" during the pelletising process and the size, shape, bulk density and residual humidity are determined.
The Extrusion unit focuses on the further processing of plastic pellets into semi-finished products, such as profiles, pipes, films, plates, foam etc. without the interim pelletising stage. Gear pumps and screen changers are used in order to optimise the extrusion process and to increase productivity. Gear pumps enhance the quality of the product thanks to their ability to transport the product constantly, relieving the extruder of pressure build-up. Screen changers separate out contamination in liquid plastic melt, helping to satisfy the growing stringency of quality requirements.
The Elastomer unit is geared towards manufacturers of basic mixtures and processors of "rubber-like" end products and semi-finished products. These impose strict demands in terms of perfect dimensional tolerances through a constant transport of material, and in terms of the high flexibility of their extrusion line through the reproducibility of various material formulas. Gear pumps, the volumetric efficiencies and flow channel geometries of which have been optimised for the flow of rubber, help to achieve and monitor these operating parameters reliably. Various tooth geometries such as spur, helical and herringbone gearing give the user the perfect choice when it comes to optimising gear pumps for a specific application.
In chemical, industrial and pharmaceutical applications, gear pumps need to transport a variety of different materials in order to be able to cover the broad spectrum of applications as effectively as possible. Whether it be highly corrosive media, high temperatures, high pressure or high viscosities that they have to deal with, or even a combination of all of them, the modular design of Maag gear pumps ensure the ideal choice of reliable, long-lasting and operationally safe products for individual customer requirements.
