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.
