Elastomer Extrusion Pumps
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
When it comes to manufacturing profiles and dealing with strainers, high requirements are placed on pumping consistency and extrusion lines. The new gear pump series extrex⁶ RV/RB from MAAG raises the performance of gear pumps for elastomer extrusion to new levels in terms of both economy and processing technology. Product quality is guaranteed by a stable discharge, the lowest tolerance deviations and achieving process stability in quick time.
Optimized flow channels
Highly efficient self-cleaning properties
Low pulsation pumping even at high differential pressures
Compact design
Gentle pressure increases
Minimal temperature increase
Leak-free operation depending on compound sensitivity possible
Extrex⁶ ER
Elastomeric processing requires positive displacement devices that gentle convey high viscosity rubber through the system. Specifically designed, low compression tooth design allow the extrex⁶ ER transfer, booster or metering gear pump to achieve both high pressure and low shear.
The rubber compound is conveyed with a constant, precise flow even at high discharge pressures – and this also for extremely dry or sticky compounds, where former pump generations reached their limits due to scorch. Additionally, their anyway high efficiency and long life span will extend unrivaled due to reduced internal friction.
