Description
 
The GEMÜ code 5M diaphragm has a two-piece design and consists of a PTFE face and a peroxide-cured EPDM backing. An FKM backing is also available for highly permeating media (GEMÜ code 5F). The PTFE used is a chemically modified second generation PTFE - called TFM TM. This material offers maximum chemical resistance and also features a considerably lower level of wear under steam conditions. 
 

 
 
Technical specifications

 
 
Features
 

• Fabric reinforced EPDM backing
• Excellent long-term tightness and vacuum compatibility thanks to improved geometry
• Extremely long service life
• Leak detection holes in the EPDM backing
• Easy-to-read identification
• Simple and defined mounting thanks to the threaded pin that is sintered in place with integrated screw-in stop (MG 25 to MG 100)

 
 
Replacement diaphragms from GEMÜ
for aseptic and industrial processes
Diaphragms are wearing parts. They need to be regularly inspected and replaced otherwise malfunctions can occur, possibly resulting in hazardous situations.
 
Specifying the maintenance cycles
The maintenance intervals for inspecting and replacing diaphragms are application-dependent. In order to determine a suitable maintenance interval, the maintenance history and the stresses placed on the parts due to frequent sterilisation, cleaning processes or frequent cycle duties must be taken into account. The type of media must also be considered; the maintenance interval is considerably shorter for viscous or abrasive working media in comparison to inert liquids, for example.
 
Inventory
If it has not yet been possible to conclusively document the maintenance interval, or if the diaphragm is only to be replaced in the event of leakage, we recommend creating a stockpile in order to be able to react promptly. However, the inventory should take into consideration that elastomer components have a maximum recommended storage and operating time. This is between one and six years for GEMÜ diaphragms – when they are stored correctly.
 
Procurement cycles
In our experience, it is worth setting up a small storage area for small, frequently used parts and establishing a rolling order system at the same time in installations with a relatively large number of diaphragm valves. In the latter case, you will automatically receive a subsequent delivery or a further delivery of diaphragms from us in a time period defined by you.
