Requirements for Chemical Pumps in Chemical Processes

Chemical pumps, the chemical industry's workhorses for aggressive, toxic, flammable or high-purity fluids, demand strict requirements beyond flow and pressure for safe, reliable operation.

Key requirements include: compatible construction materials (corrosion/erosion-resistant, contamination-free); robust sealing systems (sealless magnetic/canned motor pumps for hazardous fluids, or API - compliant mechanical seals); adherence to safety standards (leak containment, overpressure/dry - run protection, temperature control per API 610/ISO 2858); optimal hydraulic performance (matching flow/head, NPSH compliance, efficiency near BEP); and process - specific designs (sanitary CIP/SIP for food/pharma, hardened parts for slurries, metering pumps for precision feeding). Proper selection relies on full fluid and process analysis.
