European Community Directive 94/9/EC (ATEX) requires equipment in conformity with ATEX standards when intended for use in areas with potentially explosive atmospheres. John Morris Scientific offers Vacuubrand’s Category 2 chemistry diaphragm pumps and vacuum systems in conformity with ATEX (for use in zones where an explosive atmosphere is likely to occur).
These chemistry diaphragm pumps are appropriate for such locations because they are oil-free, have no sliding surfaces, and the expansion chamber is hermetically sealed against the drive zone. ATEX chemistry vacuum systems with solvent recovery provide safe, convenient vacuum while protecting the environment.
NEW: With variable speed motor for vacuum control as VARIO®-version
ATEX chemistry diaphragm pumps and vacuum systems are now available with variable speed motor for vacuum control as VARIO®-version.
The VACUUBRAND range of ATEX chemistry diaphragm pumps is supplemented by an ATEX vacuum gauge with excellent corrosion resistance and long-term stability. (Note: Compliance with EC Directive 94/9/EC does not ensure compliance with similar codes in countries outside of the EC. These pumps are not available in every location. Contact your local VACUUBRAND representative for availability.)
With the new ATEX VARIO® chemistry diaphragm pumps and vacuum systems, the vacuum can be precisely controlled by the motor speed. The VARIO® pump is driven by an additional control signal line.
The optional vacuum controller CVC 3000 with system accessories (I/O-Module, supply / isolation amplifier) and ATEX vacuum sensor enable fully automatic evaporations without the need for parameter settings or user programming. With the adaptive control it finds the boiling pressure independently and adjusts the vacuum continuously and optimally according to the vapor pressure.
The vacuum controller and system accessories are installed in a non-hazardous area.
