In high-speed pump mechanical seals, after the pump has been in operation for 1–2 months, the liquid level in the buffer tank decreases by a small amount. Why is this?

In high-speed pump mechanical seals, after the pump has been in operation for 1–2 months, the liquid level in the buffer tank drops slightly. Has this amount of sealing fluid leaked away slightly, or has it been used up somewhere else?
It’s normal to miss some; there’s no way to have a perfect seal when in contact with moisture, so just top it up regularly
Also, why is there a reservoir for the sealant connected to a circulating cooling water system for cooling? Is the temperature of the sealant determined by the temperature of the gearbox oil?
Heat conduction is one aspect; there is also frictional heat at the sealing surfaces, which must be cooled
Thank you: lol, is it the friction between the conveying medium and the sealing surface?
Sealant loss is normal and should be replenished.
Be cautious if the rate of liquid level drop accelerates
