VARIO® pumps provide precise vacuum control by adaptation of the diaphragm pump´s motor speed. The MZ 2C NT VARIO two-stage chemistry diaphragm pump meets medium vacuum requirements for most solvents. The on-demand motor speed control results in unparalleled length of service intervals for wearing parts such as diaphragms.

Performance features

  • automatic adaptation of the vacuum level throughout the process for high process reliability and unattended operation
  • short process times due to zero-fluctuation (hysteresis-free) vacuum control
  • easily operated CVC 3000 vacuum controller with clear text menus, with integrated venting valve
  • extraordinary diaphragm life for minimum operational and servicing costs
  • excellent chemical resistance
