Summary

Different industries require different pump technologies based on chemical compatibility, purity requirements, solids content, and operating conditions.

As a general rule:

· Magnetic drive pumps are best for corrosive and leak-sensitive chemicals.

· Vertical sump pumps are ideal for chemical tanks and continuous circulation.

· Self-priming pumps are suitable for low-level liquid transfer without manual priming.

· Air-operated diaphragm pumps handle sludge, slurry, and high-solid liquids while supporting dry running.

· Metering pumps provide accurate chemical dosing.

· Centrifugal pumps are commonly used for clean water and cooling water circulation.

· Submersible sewage pumps are designed for wastewater containing solids and suspended particles.
