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.
The recently developed series is characterized by the optimized conveying characteristics for gear pumps. This series expands the processing scope for temperature, degree of plasticizing and pressure build-up when working the compounds. It simplifies the operating mode of the extrusion line and dramatically improves the quality of the end product. extrex® gear pumps have optimized flow channel geometry and a temperature-controlled pump housing.
