A. Product Overview
Baumer DE and DH flush diaphragm sanitary seal is a hygienic diaphragm seal used with pressure instruments in clean and sanitary process environments. It is suitable for applications where the process media should not enter the pressure gauge, pressure switch or pressure transmitter directly.
The seal has a flush diaphragm sanitary type design, which helps prevent material buildup and makes cleaning easier. With AISI 316L SS wetted parts, it is suitable for demanding applications where corrosion resistance, hygiene and cleanability are important.
This model is suitable for pressure ranges from -1 to 0 bar and 0 to 40 bar. It can operate from -10 degree C to 180 degree C with FDA suitability or as per the selected fill fluid. Available process connections include 1 inch, 1 1/2 inch and 2 inch as per DIN 11851, DIN 32676 and SMS 1147 standards. Special material can be supplied on request depending on application requirements.
B. Working Principle
The Baumer DE and DH sanitary diaphragm seal works by isolating the pressure instrument from the process media. The process pressure acts on the flush diaphragm, and this pressure is transferred through a suitable fill fluid to the connected pressure gauge, switch or transmitter.
Because the diaphragm is flush with the process connection, the media does not get trapped inside cavities or narrow passages. This helps maintain hygienic measurement and reduces the chances of clogging, contamination, crystallization or product buildup.
The pressure instrument receives the pressure signal without coming into direct contact with the process fluid. This improves instrument life and helps maintain measurement reliability in sanitary applications.
C. Why It Is Used
Baumer DE and DH flush diaphragm sanitary seal is used to protect pressure instruments in hygienic and difficult process applications. It is especially useful when the process media is sticky, viscous, corrosive, crystallizing, contaminated or sensitive to hygiene.
It is used because it helps prevent clogging inside the pressure instrument connection. In food, dairy, beverage and pharmaceutical processes, a normal pressure connection may create dead zones where product residue can collect. A flush diaphragm sanitary seal helps reduce this issue and supports easier cleaning.
This seal is also used where the process media must not contaminate the pressure instrument and where the instrument must not contaminate the process. The AISI 316L SS wetted part construction makes it suitable for clean process industries requiring durability and hygiene.
D. Suitable Buyers
Baumer DE and DH flush diaphragm sanitary seal is suitable for buyers who need hygienic pressure measurement solutions for sanitary processes. It is commonly useful for:
Food processing plants requiring pressure measurement in clean pipelines and tanks
