Flowserve's products are designed, developed and 
manufactured with state-of-the-art technologies in 
modern facilities. The unit is produced with great care 
and commitment to continuous quality control, 
utilising sophisticated quality techniques, and safety 
requirements.  
Flowserve is committed to continuous quality 
improvement and being at service for any further 
information about the product in its installation and 
operation or about its support products, repair and 
diagnostic services. 
These instructions are intended to facilitate 
familiarization with the product and its permitted use. 
Operating the product in compliance with these 
instructions is important to help ensure reliability in 
service and avoid risks. The instructions may not take 
into account local regulations; ensure such 
regulations are observed by all, including those 
installing the product. Always coordinate repair 
activity with operations personnel, and follow all plant 
safety requirements and applicable safety and health 
laws/regulations. 

 

These instructions should be read 

prior to installing, operating, using and 
maintaining the equipment in any region 
worldwide. The equipment must not be put into 
service until all the conditions relating to safety 
noted in the instructions have been met.
 

1.2 CE marking and approvals 

It is a legal requirement that machinery and 
equipment put into service within certain regions of 
the world shall conform with the applicable CE 
Marking Directives covering Machinery and, where 
applicable, Low Voltage Equipment, Electromagnetic 
Compatibility (EMC), Pressure Equipment Directive 
(PED) and Equipment for Potentially Explosive 
Atmospheres (ATEX). 
Where applicable the Directives, and any additional 
Approvals, cover important safety aspects relating to 
machinery and equipment and the satisfactory 
provision of technical documents and safety 
instructions. Where applicable this document 
incorporates information relevant to these Directives. 
To establish Approvals and if the product itself is CE 
Marked check the serial number plate and the 
Certification.
