Type 29 Welded, High Volumetric Displacement Diaphragm Seals
Key Features
- An off-line seal with a threaded connection and all welded, all metallic housing design that does not utilize an o-ring or gasket
- Designed with a larger diameter diaphragm for higher displacement capability
- Maximum pressure rating is 2,500 psi
- A variety of upper and lower housing and diaphragm materials are available to suit most applications
- A flushing port is available to clean wetted areas and prevent process media build up
- Consider gauge size, pressure range, media composition, ambient and operating temperature, and maximum working pressure when selecting
- For process temperatures over 212 °F a capillary or cooling element is recommended, contact factory to order
- Fill fluid must be compatible with process media; i.e. glycerine may become volatile in conjunction with a strong oxidizing agent such as chlorine, forms of oxygen or peroxide and nitric acids
