Cylindrical type In-Line Diaphragm Seals are installed directly in the process flow line between two flanges. These are also called as Cell type Diaphragm seal. Cylindrical type in-line Diaphragm seal recommended when the process media is Slurr y or a liquid that contains a solid component or viscous.
The area behind the diaphragm is sealed with suitable filling fluid. As the process fluid flows though the pipe, it exer ts pressure on the cylindrical diaphragm, which is transmitted to the pressure instrument through the filling fluid. The inner diameter of the seal unit is same as that of the process pipe. Thus it is continuously washed / cleaned by the flowing process media, thereby avoid any clogging, which results in
accurate reading of the pressure instrument.
