vacorex⁶ VX

Extraction pump for the polymer industry

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

MAAG vacorex⁶ 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 is vacorex⁶ gear pump the ideal solution for such applications.
