Diaphragm pumps, Aluminium, MD 4 VARIO select

The VARIO® design provides vacuum control by precise and continuous adaption of the diaphragm pumps motor speed, and includes the vacuum pump, as well as the VACUU·SELECT controller.

  • Improved performance, increased pumping speed and better ultimate vacuum. Extend applications with non-aggressive gases whether used in the laboratory or for industrial processes
  • Very low leak rate due to enhanced leak-tight tubing connections, resulting in consistent performance characteristics - even after many years of operation. Ideal for analytical applications
  • Long diaphragm and valve lifetimes: made of highly flexible FPM, with fabric-reinforced double diaphragms for improved long term stability
  • Very quiet and ultra low vibration due to compact drive with patented motor drive system. Ideal as a built-in component for sensitive analytical equipment
  • Easy to clean due to smooth surfaces. A robust solution for numerous applications in industrial environments


Country-specific power cord versions available on request.
