used by FrymaKoruma are listed in the appended lubrication schedule.
•
The lubricants used by suppliers are listed in the respective documentation.
Sealing liquid (double-acting sliding ring seal)
The sealing liquid must be compatible with the product and free from solids. It must lack the
tendency to precipitate, should have the maximum possible boiling point, be a good heat conductor
and have a low viscosity.
A viscosity of 0.8 to max. 40 cSt (mm
2
/s) brings good results. The pressure downstream of the
pump should be between 1 and 3 bar. The boiling point should be as high as possible. A difference
in temperature of dT min. 60 – 80°C with respect to the boiling point of the medium to be sealed
should be aimed at.
The flow rate must be set such that in the case of water and similar liquids, a max. outlet
temperature of 80°C is not exceeded. In the case of solvents or alcohol, a max. temperature
difference of 60°C is permitted.
When selecting a sealing liquid, make sure that it is also compatible with the material of the sliding
ring seal.
