Aluminum Pump Vs. Cast Iron Pump

Aluminum pump body – lightweight, good for clean water, light debris, and weak corrosive liquids. Ideal for portable use (e.g., flood relief, irrigation).
Cast iron pump body – robust, handles dirty water, sand, oil, seawater, and industrial fluids. Suitable for stationary or heavy-duty applications.

Aluminum is prone to corrosion or cracking when handling:

• Strong acids/bases (e.g., sulfuric acid, sodium hydroxide)

• Chloride-rich media (e.g., seawater, brine, bleach)

• Certain organic solvents (e.g., aniline, chlorides)

• High-temperature or heavy oils

• Abrasive slurries (wear, not corrosion, but causes failure)
