Code 3A / 13 Peroxide Cured EPDM Diaphragm One Piece

Code 3A / 13 Peroxide Cured EPDM Diaphragm One Piece

Application examples:

• Water treatment plants, washing and cleaning installations

• Plants for the food and foodstuff industries, the chemical industry and electroplating

• Equipment for the photographic industry, laboratory, analytical and medical apparatus

Material:

EPDM: the best choice for extreme cryogenic pumps, as low as -51 degrees, can also be used to pump dilute acid or low corrosive liquids.

Polyperfluoroethylene propylene: high price, strong corrosion resistance, flexibility is better than PTFE, suitable for low temperature corrosive media.

Available materials: EPDM, PTFE (no industrial standard but improved composition)/EPDM; further materials depending on the scope of application

For abrasive and contaminated media: Full bore diaphragm valves and lined diaphragm valves

The minimal deadleg internal contour and the support of the diaphragm by a compressor provides optimum flow conditions and the best seal properties on GEMÜ full bore diaphragm valves. Lined diaphragm valves from GEMÜ combined with a suitable seal material offer even better resistance to numerous lyes, acids and other corrosive, abrasive and contaminated media.

Available materials: NBR, CR, natural rubber and EPDM

For sterile and hygienic applications: seal system

GEMÜ developed its seal system for diaphragm valves with a sealing weir up to DN100 over three decades ago. A circular sealing bead in the valve body creates a defined external sealing point. This minimizes the ring-shaped gap between the diaphragm and the valve body and makes this seal system particularly suitable for applications in the pharmaceutical, biotechnology and cosmetics industries.

Diaphragms, which are used predominantly in sterile applications

• ***** Highest mechanical load capacity
• ¹ The diaphragms are applicable as a moisture barrier. The valves concerned must be serviced regularly if steam is applied continuously.
• *MG = Diaphragm size

Notes:

Since plastics and elastomers are subject to natural aging, we recommend observing the GEMÜ storage conditions for shut-off diaphragms. You thereby guarantee maximum storage and service life of the diaphragms.

The temperature values are indicated irrespective of operating pressure and diaphragm size and apply to water and/or inert gases. The permissible operating pressure decreases with rising temperature and nominal size. Only specially designated diaphragms should be used for steam. The permissible operating pressure results from the steam pressure diagram.
