Elastomer Extrusion Pumps

Extrusion gear pump for elastomers and rubber manufacturing with highest performance – extrex® RV/RB

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 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.
