Improved performance, increased pumping speed (up to 16m³/h) 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 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. Whisper 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. The VARIO® design provides vacuum control by precise and continuous adaptation of the diaphragm pump·s motor speed, and includes the VARIO® pump, as well as the CVC 3000 vacuum controller.
