Handling Corrosive Chemicals

Metallic vs Plastic-Lined Chemical Pumps: Choosing the Right Solution

Selecting the right pump for corrosive chemicals is essential for safe, reliable, and efficient operations. Two common options are metallic chemical pumps and plastic-lined pumps, each offering distinct advantages depending on operating conditions, temperature, and chemical compatibility.

Metallic pumps are valued for their strength, durability, and ability to perform in demanding environments. They are ideal for high-pressure and high-temperature applications, as well as processes involving abrasive or particle-filled fluids. Their robust construction reduces wear, extends service life, and minimises maintenance requirements.

These pumps also provide broad chemical resistance, particularly stainless steel models, which can handle many acids, alkalis, and solvents when the correct alloy is selected.

Plastic-lined pumps are specifically designed for highly corrosive chemicals where metal components alone may fail. The lining acts as a protective barrier, delivering exceptional resistance to strong acids, caustics, and aggressive solvents.

While plastic-lined pumps are best suited to moderate-temperature applications, they offer superior protection against corrosion, helping to improve reliability and operational safety.

The best pump choice depends on your process requirements. Metallic pumps excel in high-pressure, high-temperature, and abrasive applications, while plastic-lined pumps are ideal when maximum chemical resistance is required.

By assessing operating conditions, temperature, and chemical compatibility, businesses can select a pump solution that improves performance, protects equipment, and ensures safe chemical handling.
