Dosing pumps for polymer systems

For more than 100 years, MAAG has been developing and manufacturing pumps at its headquarters in Switzerland. MAAG is proud of its core competence - the development and production of gear pumps for polymers, chemicals and lubricants and filtration systems for the production and processing of plastics. Today, MAAG is one of the world's leading manufacturers of elastomeric extrusion pumps, thermoplastics, extrusion pumps, industrial pumps, chemical pumps and melt pumps for polymer production. Thanks to many years of experience with production and a deep understanding of polymer production and processing processes, gear pumps of all types can be optimally adapted to individual customer requirements. Technical know-how and the ability to respond to specific customer requirements make it possible to achieve the highest possible efficiency for a given industrial process. The maximum service life of MAAG pumps and melting pumps and the minimum downtime are a great guarantee of the successful operation of industrial plants.

 

Extrex® RV/RB

Extrusion gear pump for elastomers and rubber manufacturing with highest performance

When it comes to manufacturing profiles and dealing with strainers, high requirements are placed on pumping consistency and extrusion lines. The new extrusion gear pump series extrex® RV/RB from MAAG raises the performance of gear pumps for elastomer extrusion and rubber extrusion to new levels in terms of both economy and polymer processing technology. Product quality is guaranteed by a stable discharge, the lowest tolerance deviations, and achieving process stability in quick time.
