Fives' customer service department benefits from highly qualified technicians who travel worldwide, in order to support customers during the start-up of their equipment. For pumps, commissioning is made by highly qualified teams so the quality and the safety of the start-up and the proper functioning of the pump is ensured.


Fives shares its strong experience with its customers in order to anticipate and optimize the maintenance for pumps and exchangers in the most suitable way. Defining all the needs in terms of human and material resources before going on site is the key to a successful intervention.

Thanks to this anticipation, the plant's standstill period is as short as possible, and the maintenance costs are reduced. Thanks to its specific equipment and expertise, Fives can assist its customers in order to :

  • Prevent problems during running of installation,
  • Maintain the equipment's thermal efficiency.

Fives is also able to check the state of the equipment via specific procedures:

  • Visual inspections, leak tests, non-destructive tests (our experts can interpret X-ray results on aluminum welds : level II for dye penetrant and  radiographic testing),
  • Verifying the thermal insulation (perlite),
  • Clean exchangers with problems of plugging by dry particles etc. ...


Repairs can be organized on site or in one of Fives’ workshops (Switzerland for pumps, France for exchangers, China for pumps and exchangers). As soon as Fives is contacted for on-site repair, the teams  provide direct technical support and can quickly dispatch a qualified technician anywhere in the world. Fives also takes care of pump repairs in  its own workshops. The pump is picked up repaired, and then returned to the customer, directly on site. Our workshops are equipped with all the specific tools and facilities needed to repair in the best conditions. Regarding heat exchangers, if problems are identified on site, Fives’ field service department can send a team to expertise the equipment and make the necessary repairs (such as aluminum welding).
