Operating temperature of mechanical seals
Thread Content
The medium temperature of an alkali pump in our factory is 105; what is the maximum operating temperature for self-sealing flushing it?
A flushing fluid cooler should be added to extend the lifespan； Because the temperature of the alkaline solution is high, if the pressure is not high, vaporization will occur, which has a significant impact on the mechanical seal
The flushing temperature is determined based on the operating conditions and process requirements. For certain media that are prone to crystallization or solidification at low temperatures (such as KHCO3 solutions and wax oils), it is essential to ensure that the temperature in their sealed chambers does not drop too low; for example, the temperature of the wax oil flushing fluid should be 200 degrees； For ordinary media, there are no special process requirements; generally, temperatures below 80 degrees are preferable. If low temperature has no effect on the alkaline solution, it is recommended to add a heat exchanger.
It is better for the rinsing temperature to be below 80 degrees
