    AI Overview
    Caustic soda (sodium hydroxide) transfer pumps, such as magnetic drive centrifugal, AODD, and drum pumps, are designed to safely handle highly corrosive, high-pH liquids using materials like Stainless Steel 316, PTFE, and PVDF. These pumps prevent leaks, spills, and hazardous exposure. Ideal for 50% NaOH, they offer reliable, chemical-resistant performance. 
    Key Pump Types for Caustic Soda 
    • Magnetic Drive Pumps: Sealless design provides leak-free operation, making them ideal for hazardous chemical transfer.
    • Air-Operated Double Diaphragm (AODD) Pumps: Excellent for suction lift and handling viscous or aggressive fluids.
    • Centrifugal Pumps: Reliable for high-volume, continuous transfer.
    • Drum/IBC Pumps: Designed for safe, convenient unloading from containers.
    • Peristaltic Pumps: Ideal for accurate dosing. 
    Recommended Materials 
    • Stainless Steel (304, 316, 316L): Common, durable choice.
    • Plastics (PTFE, PVDF): Provide excellent chemical resistance.
    • Avoid: Aluminum or copper alloys, which react with caustic soda. 
    Key Considerations 
    • Concentration/Temperature: High concentrations (up to 50%) and high temperatures increase corrosion rates.
    • Crystallization: Caustic soda can crystallize upon cooling or exposure to air, which can damage seals.
    • Safety: Ensure pumps are designed to prevent exposure to operators. 
    To help you select the best pump, could you tell me:
    • What is the concentration (%) and temperature of the caustic soda?
    • Are you transferring from drums/IBCs or from a large storage tank?
    • Do you need a specific flow rate (e.g., liters per minute or gallons per minute)?
