Slurry Pump Material – A33 (Duplex Stainless White Iron)

This material combines the wear resistance of high-chrome alloys with excellent corrosion resistance, particularly against acidic media. It is ideal for phosphoric and nitric acid pumps, offering outstanding performance and long service life.

Heat Treatment Hardness: HRC 35-50

Corrosion Resistance: Austenitic structure resists highly acidic environments (e.g., pH 1 sulfuric acid).

Abrasion Resistance: Carbide structure ensures durability against phosphogypsum, nitric acid, sulfuric acid, etc.

3. Slurry Pump Material – Rubber Lining

Available in natural rubber and synthetic rubber, suitable for fine, non-sharp particles.

Natural Rubber: Superior elasticity, sealing performance, and abrasion resistance.

Applications: Rubber linings are widely used in slurry pumps due to their wear resistance, corrosion resistance, and cavitation resistance, making them ideal for power plant flue gas desulfurization (FGD) systems, with a service life of up to 5 years.
