MATERIAL PROFILE
Diaphragm Material
CAUTION: Operating temperature limitations are as follows:
Operating Temperature
Max.
Min.
Viton:
Excellent corrosion resistance, resistance to various acids (including the median
concentration of oxidizing acid),alkali, salt, petroleum products, hydrocarbons, etc.
177°C
-40°C
PTFE (Teflon):
Excellent corrosion resistance, almost resistant to all chemical media (including
concentrated nitric acid and aqua regia). Except melting of lithium, potassium.sodium, chlorine
trifluoride, high-temperature oxygen trifluoride, sulfur-speed liquid fluorine.
176°C
4°C
Santoprene:
Good abrasion resistance, chemical resistance and heat resistance, suitable for
general acid and alkali, not suitable solvent. Can replace the EPDM/EPR material.
104°C
-29°C
Hytrel:
Good abrasion resistance, used in most of the neutral fluid. Can replace Bune-N
materials.
104°C
-29°C
EPDM:
Abrasion resistance, aging resistance, ozone resistance , suitable for general acid and
alkali.
122°C
-40°C
Buna-N:
Widely used in gasoline and other oil products. Suitable for use at room temperature.
100°C
-40°C
GE:
Better abrasion resistance than Hytrel, the same chemical resistance as Buna-N.
104°C
-29°C
Note: The maximum and minimum temperature is the limited operating temperature of these materials. Temperature and
pressure will affect the diaphragm life. Operating within suggested maximum and minimum temperature will maximise
the lifespan of the pump.
