Models M932.3A, M933.3A Assembled diaphragm seal For sanitary applications

Design
All-welded construction in full compliance with ‘3A’ third party standards and meets the most rigorous biopharmaceutical industry specifications. This assembly has all the advantages of the 23X.50 series mechanical gauge (ASME B40.100 & EN 837-1) and WIKA combines it with a superior designed sanitary diaphragm seal. All external stainless steel surfaces are electropolished and the wetted components have full material identification and traceability. The diaphragm and its body have matching convolution patterns to greatly reduce potential diaphragm damage due to mishandling and to minimize temperature effects.
