Polymer Production Pumps

Polymer extraction pump for the polymer processing industry – vacorex⁶ VX

Vacorex⁶ VX

MAAG introduces the vacorex® x6 class polymer extraction gear pump. vacorex⁶ ideally fulfills modern polymer production processes which require polymer pumps that can discharge at high pressure despite very low fill level and high vacuum conditions in the reactor/devolatilization vessel.

MAAG vacorex⁶ polymer extraction pumps process a wide range of different polymer grades without affecting their quality. Reliable, requiring little maintenance, and robust enough to withstand the rigors of years of operation, the vacorex⁶ polymer gear pump is the ideal solution for such applications.
