Flushing ring for diaphragm sealing systems

The main function of the flushing ring is to flush/clean the diaphragm of the diaphragm seal to prevent the process medium from crystallizing, depositing, or corroding in the sealing area, thereby protecting the seal, extending the life of the equipment and ensuring the reliability of the measurement or control system.

The flushing ring has one or two threaded holes on the side for flushing the diaphragm. The main advantage of the flushing ring is that the system can be flushed without disconnecting the diaphragm seal from the process flange. The flushing ring can also be used to vent or drain air.

There are a variety of materials available for flushing rings, including stainless steel, Hastelloy, Monel, etc., which can be selected according to the properties of the fluid and the use environment.

The reasonable design and use of flushing rings can effectively protect the diaphragm sealing system in harsh industrial environments and ensure the equipment's long-term normal operation.
