Select the right pump for acid and alkali applications
Crest Pumps, a specialist in pumps for chemical and corrosive applications, highlights some of the key considerations when selecting a PFA-lined pump for acid and alkali handling.
Handling acidic and alkaline solutions in industrial processes demands precision and the right equipment. Perfluoralkoxy-lined (PFA) pumps are a top choice for these applications due to their exceptional resistance to corrosive chemicals.
However, not all PFA linings are created equal. It is therefore important to ensure the PFA lining is able to handle the specific concentration and temperature of the acids or alkalis that it will be working with. PFA’s high chemical resistance makes it suitable for a broad range of aggressive chemicals, providing a reliable barrier against corrosion.
Focus on temperature and pressure ratings
PFA-lined pumps are known for their ability to withstand high temperatures and pressures. However, it’s crucial to verify that the pump’s ratings align with the process conditions. Overlooking this can lead to compromised pump integrity and potential leaks.
Prioritise safety features
Safety is paramount when handling hazardous chemicals. Look for PFA-lined pumps with safety features such as leak detection systems, secondary containment, and magnetic drive technology for leak-free operation. These features minimise risks and ensure compliance with safety standards.
Consider flow rate and viscosity
Selecting a pump that can handle the specific flow rate and viscosity of the fluids being pumped is also essential for maintaining efficiency and preventing wear. PFA-lined pumps are designed to manage a range of flow rates without compromising chemical resistance.
Long-term cost versus initial investment
While PFA-lined pumps may have a higher upfront cost, their extended lifespan and reduced maintenance needs make them a cost-effective choice in the long run. Investing in a high-quality PFA lining minimises downtime and prevents costly repairs due to corrosion.
Choosing the right PFA-lined pump for acid and alkali handling involves more than just selecting a corrosion-resistant material. By focusing on compatibility, safety features, and long-term cost-effectiveness, it is possible to ensure reliable and efficient chemical transfer.
