Elastomer Options

Depa Nopped E4 PTFE Compound Diaphragm

Made of high A-grade PTFE and an EPDM back up; smooth and clean surface with integrated outer piston; superior chemical resistance suitable for heavy acids and caustic products. Applications: All chemical (and transfer of aggressive chemicals, also in "EX-areas"). Temperature Range: -10°C to +130°C.

 

EPDM

Elastomer rubber with sound elastic properties; good chemical resistance for acidic and caustic media; frequently used with solvents and alcohols. Applications: Miscellaneous chemical and industrial. Temperature Range: -25°C to +90°C.

 

PTFE

PTFE diaphragm with EPDM back up; the high chemical resistance appropriate for heavy acids and caustic products. Applications: All chemical (and transfer of aggressive chemicals, also in "EX-areas"). Temperature Range: -25°C to +100°C.

 

EPDM Grey

Pale elastomer rubber material with good elastic properties and viable chemical resistance for acidic and caustic products; environments with solvents and alcohols are common applications. Applications: Food, pharmaceutical and beverage. Temperature Range: -25°C to +90°C.

 

Depa Nopped S4 (Santoprene)

Excellent chemical and wear resistance; optimal for acidic and caustic environments. Applications: All chemical and industrial. Temperature Range: -25°C to +110°C.

 

NBR

Multi-purpose diaphragm of nitrole rubber for oily or greasy service; suitable for diverse hydrocarbons, mineral oils, grease and fuels. Applications: Chemical and industrial. Temperature Range: -15°C to +90°C.

 

FKM
