7. Application Scenarios & Cases
heavy duty slurry pumps are indispensable in aggressive media transport. Their robust design and advanced materials ensure extended uptime and reduced OPEX in fields such as:
- Mining & Beneficiation: Iron ore/tin/tungsten tailings, high-concentration mill discharge (HADPP pumps handle 1.2 SG up to 5500 m³/h).
- Steel & Metallurgy: Transfer of ash/slag, lime slurry, and corrosive pickling solutions. Field data: HADPP maintains over 2.2x component lifetime vs previous legacy pumps.
- Chemical & Petrochemical: Handling of phosphoric acid, caustic soda, FGD scrubber, and process slurries. HADPP’s anti-corrosive lining resists pH 1–13.
- Municipal, Civil Water: Digester, sediment tank, highly viscous sludge pump duty (HADPP is a preferred heavy duty sludge pump in China and Southeast Asia).
- Dredging & Desert Reclamation: Sand pump in reclamation, abrasive silt transfer (solids up to 75mm, 58% by volume).

10. Professional FAQ: Slurry Pump Technology Explained
Q1. What material is best for abrasive slurry (quartz sand, iron ore)?
A1. Hi-chrome alloy A05 (27% Cr) is preferred for high-abrasion; it yields best wear resistance according to ISO 11439 corrosion-fatigue tests. For corrosive slurry, duplex stainless or elastomer are optimal.
Q2. What’s the industry standard for pump testing?
A2. Performance tests are generally based on ISO 9906:2012 (hydraulic) and ISO 5199 (general design). Hydrostatic proof is per ANSI/GB, with >1.5x design pressure rating.
Q3. How thick are HADPP pump liners and casings?
A3. Wet end liner thickness ranges from 35mm (1.4”) in smaller models up to 65mm (2.6”) in large-scale series, exceeding most industry norms for wear protection.
Q4. Which sealing solution suits high-pressure, high-solid content?
A4. Expeller seals are ideal for moderate pressure, while mechanical seals (SiC/TC faces) and gland packing are used for higher pressures and hazardous/volatile slurries.
Q5. What is the maximum solids size that heavy duty slurry pumps can transport?
A5. HADPP series handles solids up to 75mm diameter, verified in heavy-dredging and tailings lines (field test: 98% pass rate at 68mm mean size).
