Are there any requirements for the temperature of the mechanical seal flushing fluid?
Thread Content
Who can discuss from a professional perspective what the appropriate temperature range for the rinsing solution is? The impact on the sealing surface, etc
I haven’t seen any specific requirements; I think it’s generally better to keep it below 120°C, and the material of the mechanical seal should also be taken into consideration.
We can go into more detail; everyone is welcome to share their thoughts. Thank you
The temperature of the flushing fluid has a direct impact on the lifespan of mechanical seals.
It seems that generally an angle of less than 90 degrees is required, in order to prevent vaporization from affecting the pump.
I believe it is better to keep it below 40 degrees, as this can achieve the effects of flushing, cooling, and sealing.
In my opinion, it achieves a cooling effect while ensuring that the sealing ring in the mechanical seal is not affected by temperature. Use room temperature as much as possible (no need to heat or cool the rinsing fluid, which saves energy and simplifies the process)
The flushing temperature is best at room temperature, as cooling is of primary importance.
Generally speaking, it mainly depends on the material of the mechanical seal and the temperature of the O-ring. If there is only flushing fluid, with no other cooling water or double-end face seal fluid available, then the liquid temperature should not be too high.
