Two stage vacuum pump is approved to ATEX

31 July 2008

Vacuum equipment manufacturer Edwards has launched a new range of ATEX-compliant rotary vane pumps for potentially explosive environments. The RV range, of dual mode pumps is designed for applications that require either high throughputs or high ultimate vacuum.

The pumps can be configured by the user to obtain optimum pumping performance without compromising the application, offering a high ultimate vacuum down to 2 x 10-3 mbar in high vacuum mode and 3 x 10-2 mbar in high throughput mode.

These new RV pumps are available with flame proof motors with external ATEX ratings of II 2 G IIB T4 and II 2 G IIC T4 so can operate safely in environments where the gas has an auto-ignition temperature greater than 135°C and with gas groups IIB or IIC. The internal ATEX rating is II 3 G c IIB T4 where category 3 is considered appropriate for the avoidance of internal ignition. These pumps can operate in a place in which an explosive atmosphere consisting of a mixture with air of dangerous substances in the form of gas, vapour or mist is not likely to occur in normal operation but, if it does occur, can do so occasionally.
