Verfügbare Ventilsitze für Verderair Druckluftmembranpumpen

Acetal

Wide range of solvents resistant and whitstands extreme fatigue. Good level of abrasion resistance. Not for use with acids or bases. 

Polypropylene

Wide chemical compatible. Low cost alternative for general purpose chemical transfer.

PVDF (Kynar)

Excellent chemical resistance. (near PTFE but cheaper). Good abrasion and high temperature resistance.

Aluminium

Medium corrosion and abrasion resistance. Not for use with halogenated hydrocarbons strong acids or bases.

Stainless Steel 316

High level of corrosion and abrasion resistance. Can handle halogenated carbons.

Hardened Steel

Moderate chemical resistance. Good abrasion resistance.

BUNA N

Good for water, petroleum based and hydrocarbon fluids. Not for use with strong solvents or chemicals.

Geolast

Good abrasion resistance. Similar chemical compatibility as Buna N.

Hytrel (TPE)

Often used as substitute for Buna N. 

Santoprene

Good abrasion and chemical resistance. Not for use with solvents or hydrocarbons. Often substitute for EPDM.

Fluorelastomers (Viton)

High level of corrosion resistance with acids. Good resistance for steam and unleaded fuels.

Polychloroprene (Neoprene)

Very soft rubber. Good for abrasion. Limited resistant for corrosion.
