3.Analysis of material selection for key components
-Pump Body: High-strength ductile iron (QT450)
Analysis: Compared to ordinary gray iron, ductile iron has higher tensile strength. Iraq experiences large temperature differences between day and night, and the transportation conditions in industrial areas are complex; ductile iron effectively prevents stress cracking and physical impact damage.

- Impeller: Wear-resistant high-chromium alloy (Cr27) or stainless steel (316L)
Analysis: Wastewater often contains a large amount of hard sand. Cr27 has extremely high hardness, specifically designed to resist sand abrasion; if the medium contains acidic wastewater from oil refineries, 316L is used to provide excellent chemical corrosion resistance.
- Seals: Silicon carbide (SiC) mechanical seal
Analysis: Employs a "hard-to-hard" end-face mating design. In sandy environments, ordinary seals are easily worn; silicon carbide seals prevent tiny particles from entering the sealing surface and causing failure.
This order shipped to Iraq is not only a testament to the durability and reliability of PUMPWISE products, but also another important milestone for the brand in its global market expansion and response to the demand for efficient water treatment. Iraq's harsh climate places extremely high demands on the temperature resistance and stability of its machinery. PUMPWISE, with its rigorous manufacturing processes and high-quality material selection, successfully passed the multi-dimensional assessments of its international client.
