How often should a chemical feed pump be calibrated?

Calibrating a chemical feed pump every shift is essential for maintaining accuracy and ensuring that the correct dosage of chemicals is being supplied into the water treatment process. This frequent calibration helps identify any discrepancies in pump performance that may occur due to factors such as wear and tear, changes in fluid viscosity, or other operational variables.

Conducting calibration each shift allows operators to promptly adjust the pump's settings as needed, thereby preventing overfeed or underfeed of chemicals, which can lead to operational inefficiencies, safety hazards, or regulatory violations. While less frequent calibrations, such as daily or monthly, might be adequate under stable conditions, the dynamic nature of water treatment systems often necessitates more regular checks to ensure consistent and accurate chemical dosing.

The need for every shift calibration reflects industry best practices aimed at ensuring optimal performance and compliance with safety and quality standards in water treatment.
