The combination of speed controlled VARIO^® chemistry diaphragm pumps and the new VACUU·SELECT vacuum controller makes the VARIO^® select chemistry pumps the ideal solution for chemical processes that require precise vacuum, such as rotary evaporation, vacuum drying or vacuum concentration.

• High chemical resistance and therefore ideally suited for pumping aggressive gases and vapours.
• Short process times and smooth running due to optimal setting of the pressure via the VACUU·SELECT controller.
• The VARIO^® technology controls the vacuum precisely and efficiently via motor speed.
• Power consumption, maintenance and noise are exceptionally low.
• The outlet catchpot and solvent condenser combine to prevent solvent vapor emissions into the lab, allowing for nearly full recovery of solvents.

Country-specific power cord versions available on request.

ATEX chemistry diaphragm pumps offer all advantages of oil-free chemistry diaphragm pumps. Typical applications are rotary evaporators and drying ovens with potentially explosive atmospheres. The ATEX approval includes the interior of the pump (in contact with pumped gases) as well as the surrounding area of the pump.

• Outstanding chemical resistance and superior vapor tolerance
• Mainly made of antistatic materials
• Flame proof motor with integrated, self-locking overload and excess temperature protection for direct 230V / 50Hz single phase power supply
• Overpressure safety relief valves internally and at outlet
• With separate gas ballast connection part for use of inert gas
• Safety diaphragm technology with option for inert gas purge and detection of diaphragm breakage

ATEX compliance:
Pump chamber (pumped gases): II 2G IIC T3 X
Exterior space (pump environment): II 2G IIB T4 X (with inert gas purging) / II 3G IIB T4 X (without inert gas purging)

The VACUU LAN^® local vacuum network allows multiple work stations to be connected to a single vacuum pump. This is useful for almost any conventional vacuum application in a chemical laboratory VACUU LAN^® can be directly incorporated into new laboratory installations or retro-fitted. All assemblies have integral check (1-way) valves. A practical and economical solution for multiple vacuum users in a single laboratory.
