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...

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...
