Laboratory vacuum pump MV 2 VARIO select

double-diaphragmdiaphragmmulti-stage

Overview

• VACUU·SELECT vacuum controller with graphical user interface and predefined applications simplifies laboratory workflows
• Automatic boiling point detection and vacuum adjustment to shorten process times
• Extended diaphragm lifetime for reduced operating and maintenance costs
• Contamination-free, oil-free pumping and evacuation
• Excellent ultimate vacuum; improved ultimate vacuum in VARIO® TURBO·MODE for use as backing pump for turbo pumps

Product description
Four-stage oil-free diaphragm pump designed for continuous pumping of non-corrosive gases at fractional millibar vacuum levels. Wetted parts are aluminium, stainless steel and selected plastics suitable for a wide range of applications. The MV 2 VARIO select continuously adapts motor speed to maintain the required vacuum, providing very quiet operation, ultra-low vibrations and high leak tightness. The fabric-reinforced double FKM diaphragm delivers extended service life. The VARIO® design combines the variable-speed pump with the VACUU·SELECT vacuum controller (external gauge head); demand-responsive motor speed control further extends diaphragm and valve lifetimes.
