Flushing rings are required for flange-mounted and pancake type remote seals, Article No. 7MF4800 ... 7MF4823, if the danger exists that the process conditions and the geometry of the connection could cause the process to form deposits or blockages.
The flushing ring is clamped between the process flange and the remote seal.
Deposits can be flushed away from the diaphragm through the holes in the side, or the pressure volume can be vented.
Different nominal diameters and forms permit adaptation to the respective process flange.
