IHC Pump Shaft Seal Acquires ATEX 95 Certificate

November 2, 2011

IHC Lagersmit acquires ATEX 95 certificate for its LIQUIDYNE pump shaft seal.

IHC Lagersmit, part of IHC Merwede, has acquired the ATEX 95 registration for its LIQUIDYNE pump shaft seal. This registration signifies compliance with the European guidelines, which must be met in order for equipment to be used in potentially explosive atmospheres. The ATEX 95 registration has been issued by DEKRA Certification, which judged and approved the Technical Construction File for the LIQUIDYNE series, types LDS, L2T and L3T. The ATEX guidelines (Directive 94/9/EC) are published by the European Union and dictate the rules with which products used in potentially explosive atmospheres must comply. Examples of these environments are (petro) chemical production facilities, energy plants and offshore platforms.

IHC Lagersmit specialises in sealing solutions for rotating shafts in ships, pumps, tidal turbines and other equipment. The LIQUIDYNE pump shaft seal is approved for use in zones one and two (potentially explosive gas atmospheres) and zones 21 and 22 (potentially explosive dust atmospheres). IHC Lagersmit expects an increased number of applications of the LIQUIDYNE seal for (cooling) water pumps in these types of environments.


“The big benefit of the LIQUIDYNE seal is its reliability, which results from its predictable lifetime and active condition monitoring function. The ATEX registration adds increased credibility to the safety and reliability of the LIQUIDYNE”, explains IHC Lagersmit Product Specialist Stefan Kraaij.
