Flushing rings in diaphragm seal systems have several advantages

The extension of a flanged diaphragm seal system using a flushing ring brings significant advantages. Among other things, it enables easy cleaning and, in addition, on-site calibration of the measuring location.
Diaphragm seal systems are used in processes with critical media. During some process steps, such as shutting down and cooling down the processes, media sticks to the diaphragm of the diaphragm seal. This results in measurement inaccuracies and, in the worst case, even leads to the failure of the measuring location.

Cleaning without disassembly
Where such a danger can occur, the diaphragm should be regularly cleared of deposits. The integration of a flushing ring between the flange-type diaphragm seal and the process flange saves on time-consuming disassembly of the measuring system. pressure gauge 10 bar is carried out via the bore of the flushing ring. A needle valve or a ball valve can also be attached to the flushing ring for a problem-free supply of the respective cleaning medium.
Possibility of on-site calibration
However, the function of the flushing ring in a diaphragm seal system is not exhausted with just this. It also enables – in conjunction with an upstream shut-off valve – simple on-site calibration of the measuring location. pressure gauge can also be vented or drained via the bore and valve. Users can also take samples of the process medium using a flushing ring.
