Depa Closed Surface Diaphragms Series Nopped E4

Building upon the success of the DEPA® nopped E4® PTFE Compound Diaphragm, the new DEPA® CLOSED SURFACE DIAPHRAGM SERIES is designed and manufactured in-house. The diaphragms ar available in EPDM, EPDM Grey, NBR, NRS, FKM* and PTFE compound. Temperature Range: PTFE Compound -10 to +130 | NBR -15 to +90 | EPDM -25 to +105 | EPDM Grey -25 to +90 | FKM* -5 to +120 | NRS -15 to +70

 

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

Elastomer rubber with good chemical resistance and applicable for hydrocarbons, acidic, and caustic media. Withstands elevated temperatures. Applications: Miscellaneous chemical and industrial. Temperature Range: -5°C to +120°C.

 

NRS

Versatile multi-purpose natural rubber elastomer with good wear characteristics and elasticity, especially well-suited for abrasive products and highly diluted caustic and acidic media and water. Applications: Applications with solid content and heavy duty applications. Temperature Range: -15°C to +70°C.
