Des matériaux résistants à l’usure pour les pompes à eaux usées industrielles

Des matériaux résistants à l’usure, tels que la fonte grise, l’acier inox (acier duplex) et la fonte trempée garantissent une protection optimale et un fonctionnement sans incidents des pompes à eaux usées.

Material_img es propriétés corrosives et abrasives des eaux industrielles requièrent l’emploi de matériaux spécifiques pour les pompes à eaux usées. Les pompes à eaux usées de KSB, comme la pompe submersible Amarex KRT, la pompe pour installation sèche Sewatec et la pompe en tube Amacan, sont conçues dans des matériaux offrant une excellente tenue à l’usure.

  2. Stainless Steel (Duplex Steel)
  3. Wear-resistant White Cast Iron

Cast iron – for parts subjected to extreme stresses

Cast iron offers value for money and is highly wear-resistant. Its compressive strength makes it a well-suited material for parts subjected to extreme stresses.

Cast iron is used for handling the following fluids in industrial waste water management:

Stainless steel (duplex steel) – for excellent chemical resistance

Rust-proof and acid-resistant stainless steel (duplex steel) is particularly suitable for use in the chemical and process industries. It provides protection against pitting and stress corrosion.

Stainless or duplex steel pumps have a long service life, even when operated in waste water containing phosphorous and sulphuric acid. They are resistant to pitting corrosion and, thanks to the low carbon content, intergranular stress corrosion. Stainless steel (duplex steel) is used for handling the following fluids in industrial waste water applications:

Brackish WaterK, F
Corrosive industrial waste waterK, F

White cast iron – used for highly abrasive fluids

Wear-resistant materials such as white cast iron are used for highly abrasive fluids. The chromium-molybdenum alloy cast iron features a notably higher wear resistance than other cast iron materials.

KSB’s white cast iron is an alloyed cast iron to DIN 1695 and harder than hardened chrome steel. Wear-resistant pumps from white cast iron are used for handling the following fluids in industrial waste water applications:

Fluid pumpedRecommended impeller type *)
Highly abrasive industrial waste water causing wear (chemically neutral)

Wash water containing solidsK, F
Waste water containing dust or ashK
