5. Tubing Connections: Reconnect all inlet and outlet tubing to the new accessory. Ensure all connections are tight and secure to prevent leaks.
6. System Priming and Testing: Slowly open the valves and prime the pump according to the main pump's manual. Check for any leaks during initial operation.

5. Operation

As an accessory, this component facilitates the core function of your SEKO electromagnetic diaphragm metering pump. Its operation is directly integrated with the pump's overall functionality. Once properly installed, the accessory will enable the pump to accurately meter and dispense fluids as per the pump's settings. For detailed operational instructions, including flow rate adjustments and calibration, please refer to the comprehensive user manual provided with your specific SEKO metering pump model.

6. Maintenance

Regular maintenance of your pump accessories is crucial for extending their lifespan and ensuring consistent pump performance.

• Routine Inspection: Periodically inspect the accessory for any signs of wear, cracks, leaks, or corrosion. Pay close attention to the diaphragm and tubing connections.
• Cleaning: Depending on the pumped fluid, regular cleaning of the pump head and connections may be necessary to prevent buildup and ensure accurate dosing. Use cleaning agents compatible with the accessory materials and the pumped fluid.
• Diaphragm Replacement: The diaphragm is a wear part and will require periodic replacement. Refer to your main pump manual for the recommended replacement schedule and procedure.
• Storage: If the pump or accessory will be out of service for an extended period, ensure it is thoroughly cleaned and stored in a dry, clean environment.

7. Troubleshooting

If you encounter issues with your pump after installing this accessory, consider the following common troubleshooting steps. For more complex problems, consult the main pump's troubleshooting guide or contact technical support.

• Leaks: Check all tubing connections for tightness. Inspect the diaphragm and pump head for cracks or improper seating. Ensure O-rings and seals are correctly installed and not damaged.
• Incorrect Flow Rate: Verify that the accessory is correctly installed and not obstructed. Ensure the main pump's settings (stroke length, frequency) are correctly adjusted. Check for air bubbles in the suction line.
• Noisy Operation: This could indicate air in the system, loose connections, or a worn diaphragm. Bleed the system and check all fittings.
• Pump Not Priming: Ensure the suction line is fully submerged and free of air. Check for leaks in the suction line or pump head.
