DEPA E4 membrane

E4® diaphragm in EPDM, NBR, NRS or FKM. Revolutionary "nubby" surface for best performance.

  • New design - less strain on the membrane and therefore longer lifespan
  • Less number of parts - easier maintenance
  • Integrated shaft - minimises risk of leakage
  • Modular - suitable for all Depa diaphragm pumps
  • 'Nubbly' surface for increased longevity
  • PTFE - superior chemical resistance
  • Integrated shaft - minimises risk of leakage
  • Smooth membrane surface - reduces the risk of coating on the membrane and provides increased pumping capacity.
