In and industrial plant, mechanical Seals can be considered as a fuse. Installed in very critical applications, could be the cause of production shutdown, increasing maintenance costs and reason of failure could be related to the operating conditions, the stresses coming from the machine, but also on how the plant is operated.

A chemical deposition treatment normally applied on silicon carbide rings, allows to have a diamond film, increasing the chemical and tribological characteristics.

Thanks to this development, Fluiten Mechanical Seals developed with “FLUIDIAMOND” technology can tolerate operations with poor lubrication, in “Dry Running” conditions and to be used where the PxV factor (operating pressure x peripheral speed) reaches highly critical high.



  • Minimum friction coefficient
  • High resistance to abrasion
  • Excellent thermal conductivity
  • Wide resistance to chemical aggression
  • High corrosion resistance



  • Young’s modulus: 950 ÷ 1100 GPA
  • Coating thickness: 5 μm
  • Roughness: 0,02 ÷ 0,04 μm
  • Coeficent of friction in dry running conditions: 0,01 – 0,15
  • Hardness: 2000 HV
  • Thermal conductivity: 550 W/mK



  • Pharmaceutical and Biotechnology: “Fluilift” Mechanical Seals with zero process contamination.
  • Food: Sealed with materials in accordance with EC regulation 1935/2004.
  • Oil & Gas: Pipiline Pumps, well water injection, multiphase and “Heavy Duty” applications.
  • Power: Boiler feed and hypercritical pumps in the nu-clear sector.
  • Chemical: Applications with slurry, abrasive fluids, acids and bases.



Installation with Fluiten “FLUIDIAMOND” seals technology allows to reach very long operating times, reducing a lot the maintenance activities and operating costs.

Transformation of existing seals with FLUIDIAMOND solution in pharmaceutical applications eliminates possible contamination of sterile processes.

In the chemical, petrochemical and petroleum industries, the reduction of absorbed power obtained with FLUIDIAMOND is significant for cost reduction also. Energy savings can be about 50%, compared to a mechanical seal with traditional materials.


  • Temperature: – 40 ÷ 200 °C
  • Pressure: 0 ÷ 150 barg
  • Rotation speed: 40 m/sec
