VACUUBRAND733300ca. 444 mmca. 361 mmca. 17.7 kg

This chemistry vacuum pumping unit is an economic space-saving solution for simultaneous operation of two independent vacuum applications with one single pump. Each vacuum port is equipped with a CVC 3000 vacuum controller with solenoid valve for electronic vacuum control. Both vacuum ports have integrated check valves against cross contamination and interference. The popular MZ 2C NT two-stage chemistry diaphragm pump is the heart of this pumping unit. It is frequently used for medium-sized vacuum applications involving "common" solvents. The exhaust waste vapor condenser is outstandingly efficient and compact. It provides near-100-percent recovery of solvents, for economical recycling and environmental protection.

Performance features

  • optimized vacuum even with gas ballast
  • two intuitive CVC 3000 vacuum controllers with clear text menus, with integrated venting valve
  • two chemistry-design solenoid valves with large cross section for unrestricted performance
  • simultaneous operation of two independent vacuum applications
  • excellent environmental friendliness due to efficient solvent recovery
