Overview
ATEX RV pumps have an external ATEX classification of Ex II 2G IIC T4 or Ex II 2G IIB T4 and are suitable for use in potentially explosive atmospheres. They share the same internal ATEX classification as our standard RV pumps, namely Ex II 3G c IIB T4. ATEX pumps with flameproof motors require the user to provide 2 off hazardous area cable glands and cables. In addition, connection of the thermistors to an appropriate safety circuit must be made to switch off the pump if overheating occurs. The pumps are supplied with the Gas Ballast port plugged. When pumping flammable gasses or vapours you must fit an inert gas purge to this port to dilute such gases or vapours below the lower explosive limit.
Supplied with 1 litre of Ultragrade 19 oil, inlet filter and O-ring.

Technology
All our RV pumps are significantly quieter – noise levels of 48 dBA 50Hz are typically half the noise of a conventional pump and have been achieved by extensive work on the drive train and motor.
The pumps have the unique ability to deliver excellent ultimate vacuum in both high vacuum and high throughput modes with or without gas ballast. This gives the user an unrivalled opportunity to select the optimum pumping performance without compromising the application.
The simple to use mode selector and accessible, three-position gas ballast control allow the pump to be reconfigured at any time, even when the pump is running.
