ATEX pumps
In explosive areas, only operating materials with ATEX conformity may be used. VACUUBRAND offers chemistry diaphragm pumps and pumping units category 2 (for example, for zone 1) with ATEX conformity. Thanks to their high degree of chemical resistance, their oil-free operation, the absence of sliding surfaces, as well as the hermetic seal of the pump chamber against the drive zone, chemistry diaphragm pumps offer excellent conditions for avoiding sources of ignition. Chemistry diaphragm pumps with a separator (AK) and emission condenser (EK) for solvent recovery represent proven configurations for effectively reducing workloads and they protect the environment.

ATEX pumps
Variants with VARIO® control
Oil-free, chemically resistant diaphragm pumps with ATEX conformity category 2 for use in explosive areas.
Using the VACUU·SELECT controller, you control the vacuum and process steps intuitively using the touch display. VARIO pumps control the vacuum by adjusting the motor speed. It offers the utmost precision, maximum efficiency and is especially quiet.
The suction-side separator (AK) collects droplets. The pressure-side emission condenser (EK) enables nearly 100% solvent recovery.

Technical highlights
Safety through ATEX conformity
Chemistry diaphragm pumps offer excellent conditions for avoiding sources of ignition through their lack sliding surfaces as well as the hermetic seal of the pump chamber against the drive zone.
ATEX pumps are also equipped with additional safety features against sources of ignition. These include a flameproof motor with integrated overtemperature protection and safety diaphragm technology with the option of inert gas purging and diaphragm tear detection. The ATEX approval includes the inside of the pump (pumped gases and vapors) as well as the pump environment (installation location).
All of the advantages of the chemistry diaphragm pumps
VACUUBRAND chemistry diaphragm pumps offer uncompromising chemical resistance and unsurpassed long-term performance – even in the case of aggressive chemicals. All wetted parts are made of chemically resistant fluoroplastics. Thanks to the long diaphragm service life and the low-maintenance construction, the pumps require only minimal maintenance and run very reliably for years.
Because of the dry and completely oil-free operation, chemistry diaphragm pumps are ideally suited for clean processes and the production of pure products. They do not generate either used oil or wastewater. They are therefore particularly resource-saving and environmentally friendly.
Smart vacuum control, efficient processes
Precise, efficient, and quiet – ATEX VARIO pumps control the vacuum according to need via the motor speed. VACUUBRAND optionally offers an ATEX vacuum sensor and the versatile VACUU·SELECT vacuum controller with related system accessories for installation outside of explosive areas.
With the VACUU·SELECT controller, they achieve the optimal conditions for reproducible processes. Parameters and process steps can be easily adjusted and saved using the touch screen display. The corresponding interfaces enable integration in modern laboratory networks.
