BrandTech™ VACUUBRAND™ MZ 2C VARIO Select Chemistry Diaphragm Pump

VACUUBRAND™ MZ 2C VARIO Select Chemistry Diaphragm Pumps offers users unsurpassed control of critical vacuum applications. A low maintenance oil-free chemistry-design pump is integrated with a variable speed motor and a mercury-free, digital controller. The system automatically finds and follows boiling curves, continuously optimizing the vacuum level without having to program presets. It's the ultimate productivity tool!

Easy-to-use, the VACUU·SELECT® controller provides a touch screen, application-based interface. Creating a new application is as easy as swiping a finger to drag-and-drop application building blocks.

Product Features:

  • VACUU·SELECT® controller
    Controller has a touch screen interface and predefined applications. It is easy-to-use and the modification of existing applications, or creation of new applications, is simple with drag-and-drop editing.
  • Improved Productivity
    The self-adjusting VARIO® systems require minimal oversight, freeing up time for other work. Plus, their continually optimized vacuum levels speed evaporation by up to 30%!
  • No Oil Changes
    These vacuum pumps utilize diaphragm vacuum technology. The totally dry operation eliminates the misting, handling and disposal of contaminated waste associated with rotary vane pumps. No oil to change or monitor!
  • Reduced Maintenance
    Typical diaphragm lifetimes are well in excess of 15,000 hours of use before replacement - that's years in most applications, minimizing downtime and service costs. When it is finally time for service, their unique design eliminates tedious, trial-and-error stroke length recalibration.
  • Reliability
    All VACUUBRAND® pumps and systems must pass rigorous product testing before leaving the factory. It's your assurance of a reliable pump.
