The Advantage of a Ductile Iron Casing with Fully Bonded ETFE Lining

• Enhanced Corrosion Resistance:
  
  • Ductile Iron Base: While ductile iron is inherently strong, it can be susceptible to corrosive environments.
  • Fully Bonded ETFE Lining: ETFE (ethylene tetrafluoroethylene) is highly resistant to a wide range of chemicals, acids, and bases. The fully bonded nature of the lining ensures that the protective layer adheres permanently to the ductile iron, preventing corrosive media from attacking the underlying metal. This results in a longer pump life, even when handling aggressive fluids.
• Improved Abrasion and Erosion Resistance:
  The ETFE lining offers excellent resistance to abrasion and erosion, which is particularly beneficial in applications where the pump handles abrasive slurries or particulates. This minimizes wear on the pump casing and helps maintain performance over time.
• Increased Durability and Structural Integrity:
  
  • Ductile Iron Strength: Ductile iron is known for its toughness and ability to withstand impact and high-pressure conditions.
  • Combined Protection: With the ETFE lining providing a chemical and wear-resistant barrier, the overall structure is better protected from both mechanical and chemical stresses. This synergy enhances the pump’s durability, making it suitable for demanding industrial environments.
• Extended Service Life and Reduced Maintenance:
  The protective ETFE layer minimizes internal wear and reduces the frequency of maintenance interventions. This results in lower long-term operating costs and less downtime, making the pump more reliable in continuous or critical applications.
• Smooth Flow and Efficiency:
  ETFE has a low friction coefficient, which can contribute to a smoother internal surface for fluid flow. This helps maintain the pump’s hydraulic efficiency by reducing turbulence and minimizing energy losses during operation.
• Versatility in Harsh Applications:
  The combination of ductile iron’s mechanical strength and ETFE’s chemical resistance makes these pumps well-suited for a wide range of industries, including chemical processing, wastewater treatment, mining, and other applications where fluids can be both corrosive and abrasive.
• Cost-Effectiveness Over Time:
  Although the initial investment might be higher than standard casings, the extended service life, reduced maintenance costs, and minimized downtime contribute to significant long-term savings. The pump’s reliable performance also reduces the risk of costly process interruptions.
