Tips to Choose the Right Chemical Process Pump

Prioritize Material Compatibility: Start with the "wet end." Match your chemical's pH and concentration to the right material. Use Stainless Steel (316L) for general solvents, Polypropylene or PVDF for strong acids, and PTFE linings for the most aggressive environments.

Select the Correct Seal Design: For hazardous or high-value fluids, consider sealless magnetic drive pumps to eliminate the risk of leaks entirely. If a mechanical seal is required, a double mechanical seal with a barrier fluid provides an extra layer of protection against toxic emissions.

Account for Specific Gravity and Viscosity: Chemicals are often denser or more viscous than water. Ensure your motor is sized with enough "brake horsepower" to prevent overloading when pumping heavy liquids like concentrated sulfuric acid.

Check Standards Compliance: Decide between ANSI B73.1or ISO 5199. These standards ensure dimensional interchangeability and high reliability for chemical duty.
