    Tips: How to do maintenance on a diaphragm dosing pump?

    • Regular Inspection: Routinely check for leaks, loose fittings, and worn components. Ensure that the diaphragm is intact and free from damage.
    • Diaphragm Replacement: Diaphragms are wear-prone parts. Replace them according to the manufacturer's recommendations or if they show signs of wear or damage.
    • Valve Maintenance: Inspect valves for clogs, leaks, or corrosion. Clean or replace them as needed.
    • Seals and O-rings: Examine seals and O-rings for wear and tear. Lubricate them as suggested by the manufacturer, or replace them if damaged.
    • Suction and Discharge Lines: Clear any blockages in the lines to maintain consistent flow. Ensure that the lines are securely connected.
    • Pressure Relief Valve: Check and test the pressure relief valve to guarantee system safety.
    • Electrical Components: Inspect electrical connections and controls for proper functioning.
    • Chemical Compatibility: Ensure that the metering pump is compatible with the chemicals being used, and follow guidelines for chemical handling and safety.
    • Record Keeping: Maintain a maintenance log to track service dates, component replacements, and issues encountered.
