SimMS, Mechanical Seal Simulation

SimMS is a simulation software specialized for Mechanical Seals Calculations and usable directly online.

In a Mechanical Seal, the thin lubricating film and the seal rings are highly coupled and many physical phenomena are in interaction.

The mathematical model of SimMS is come from many scientific works on Tribology and Lubrication.

Multi-Physical Simulations

A multi-physical approach is needed to obtain credible predictions including for the mass flow rate or the dissipated power. The standard engineering softwares are inadapted for Mechanical Seals Calculations.


  • Leakage rate
  • Dissipated power
  • Distance of the seal rings
  • Thermomechanical deformations
  • Pressure and temperature fields
  • Temperature in the solids 
  • Film thickness field
  • Contact and fluid forces

what is taken into account

  • Thermomechanical deformations
  • Seal rings material
  • Sealed fluid properties
  • Liquid or gas lubrication
  • Flow regime (laminar or turbulent)
  • Cavitation
  • Centrifugal intertia
  • Roughness and waviness of the faces


Scientifically Relevant

SimMS is produced and maintained in partnership with an expert internationally recognized on Mechanical Seals.

Easy to use

With SimMS you can just specify the operating conditions to obtain common outputs as the mass flow rate or the dissipated power.


SimMS is usable directly online with an internet connection from different media (PC, tablet or mobile) 

SimMS is intended for professionals who have needs and requirements for mechanical seal expertise for R&D or to improve their custumer service. Already used by some large industrials groups, our objective now aims to widly distribute SimMS by relying of distribution in SaaS (Software as a Service) so that SimMS become a reference for mechanical seals calculations.
