Diaphragm pump market demand increases, many units in the procurement of diaphragm pump, diaphragm pump accessories one of the fittings of the diaphragm material is not very understanding. Normal rubber diaphragm is suitable for the transport of neutral liquid, if there are acid, alkali and other corrosive chemical components in the liquid, need to add PTFE diaphragm. PTFE is polytetrafluoroethylene, temperature and corrosion resistance are quite good, can be resistant to corrosion of any medium, the color is absolutely white, a fluorine lined pipeline, valves, seals, bars and so on.


Diaphragm pump market demand increases, many units in the procurement of diaphragm pump, diaphragm pump accessories one of the core parts of the diaphragm material is not very understanding. Normal rubber diaphragm is suitable for the transport of neutral liquid, if there are acid, alkali and other corrosive chemical components in the liquid, need to add PTFE diaphragm. PTFE is polytetrafluoroethylene, temperature and corrosion resistance are quite good, can be resistant to corrosion of any medium, the color is absolutely white, a fluorine lined pipeline, valves, seals, bars and so on.

Diaphragm material selection | |
NRB | Oil: machine oil, diesel oil and other temperatures 0-70 degrees, |
Santoprene | Paint, weak acid and alkali and other special weak corrosive liquid, temperature 0-100 degrees |
PU | Mortar, sludge, and other normal temperature liquids with relatively large wear: |
PTFE or composite diaphragm plate | Corrosion is bigger, exports have pressure, and temperature are: teflon or composite diaphragm plate. |
