DEPA® Closed Surface Diaphragms Series Nopped E4®

Building upon the success of the DEPA nopped E4® PTFE Compound Diaphragm, the new DEPA® CLOSED SURFACE DIAPHRAGM SERIES is designed and manufactured in-house and offers the following key features and benefits:

• EXTENDED LIFETIME
  The absence of the outer piston reduces wear around the flexing area, increasing diaphragm life.
• ELIMINATES LEAKS
  Integrated insert eliminates a potential leak path within the pump. The pre-defined
  
•  fixing feature of the outer rim design improves safety for both the customer and environment.
• EASE OF MAINTENANCE
  Pump maintenance is simplified and requires only hand tightening of the diaphragm. Modular design ensures all diaphragms are interchangeable with all DEPA® pumps.
• EASY TO CLEAN
  Clean surface reduces the build-up of impurities, improves flow and increases energy savings.

The innovative nopped design facilitates stability and increases durability due to lower mechanical stress. The combination of elastomer with aluminium insert secures an easy fixation and improves stability of the diaphragm during installation and operation. The laminated design of the DEPA nopped E4® PTFE compound diaphragms ensures the diaphragm surface is impermeable. The PTFE layer enables the use of the diaphragm in a wide range of chemical application. The EDPM back-up is electrically conductive, making it suitable for use in ATEXconforming pumps.
