Key Considerations For Selecting Chemical Centrifugal Pumps

Focus on the following parameters during selection:

Flow rate and head: Match these to process requirements; for example, transporting concentrated sulfuric acid requires a pump with low flow and high head.

Material compatibility: The pH, temperature, and concentration of the medium determine the pump material (e.g., 316L stainless steel for weak acids, CD4Mcu alloy for strong acids).

Seal type: Mechanical seals are suitable for general operating conditions, while magnetic drive pumps or canned motor pumps are appropriate for applications requiring zero leakage.

Energy efficiency rating: Prioritize high-efficiency motors (IE3 or higher) to reduce long-term operating costs.
