ROTAN and the ATEX directives 94/9/EC and 1999/92/EC Superior guideline for users of equipment in potential explosive atmospheres

ROTAN® Pumps and the ATEX directives Scope The European Parliament has agreed that as from June 30 2006 the same regulations will apply to both manufacturer/supplier and end-user in the EC when operating non-electrical equipment and protective systems intended for use in potentially explosive atmospheres i.e., gas, vapour, mist and dusts. This means that equipment for use in potentially explosive atmospheres has to follow directive 94/9/ EC and 1999/92/EC . This document describes "Equipment- GROUP II category 2” and the precautions to be taken for ROTAN® pumps intended for use in zone 1 and...

The following devices are optional or additional safety features: Temperature monitoring • PT 100 sensor • Temperature labels Protection against momentary pressure rise inside the pump • Integral pressure relief valve Protection against dry run • 'Liquiphant' (resonance probe) by Endress Hause for viscosities up to 10.000 cSt pressure up to 64 bar / 28 psi. Notes 1. Directive 94/9/EC of the European Parliament and the Council of 23 March 1994 on the approximation of the laws of the Member States concerning equipment and protective systems intended for use in potentially explosive atmospheres....

V ROTAN’ can supply equipment under: Category 1 Zone 0 - GAS Areas with a gas/air mixture occur continuous or for longer periods. Zone 20 - DUST Areas where a cloud of combustible dust occur continuous or for longer periods. Category 2 Zone 1 - GAS Areas where a gas/air mixture occur occasional. Zone 21 - DUST Areas where a cloud of combustible dust occur occasional. Category 3 Zone 2 - GAS Areas where a gas/air mixture occur exceptionally or for short periods. Zone 22 - DUST Areas where a cloud of combustible dust occur exceptionally or for short periods. The temperature class is among others...

PT100 sensor To ensure that a ROTAN® ATEX pump is safe to use in an ATEX-defined area the following instructions must be followed. ED pumps and pumps with soft shaft seal must always be installed with a PT100 sensor according to DESMI A/S instructions. If the ROTAN® ATEX pump is fitted with a bypass valve, a PT100 sensor has to be mounted on the bypass valve. If a ROTAN® ATEX pump is ordered with PT100 sensor, the PT100 sensor is not mounted from the factory, due to the risk of damaging it during transport. Before the first start up of the pump the PT100 sensor must be mounted in accordance with...
