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
