Druckluft Doppelmembranpumpe Evora LDE 100M (1")

Product information "Druckluft Doppelmembranpumpe Evora LDE 100M (1")"

Explosion-proof double diaphragm pump for aggressive chemicals

The LDE 100M PVDF-TPV/PTFE is the premium model for highly aggressive media in chemical and process applications. The PVDF housing withstands oxidising and corrosive liquids, whilst the PTFE diaphragm ensures maximum sealing performance and a long service life.

This version is particularly suitable for chemically contaminated waste water, etching solutions and highly concentrated acids or alkalis. Thanks to its dry-running protection and robust air valve, it operates reliably – even under extreme conditions.

  • Premium design for aggressive media
  • Maximum chemical resistance and durability
  • Ideal for process chemistry
