4. Installation and Setup

Replacing diaphragms and valves in a diaphragm pump requires careful attention to detail. Always refer to the original Comet APS145 Diaphragm Pump service manual for detailed, step-by-step instructions specific to your pump model. The following are general guidelines:

1. Safety First: Ensure the pump is completely depressurized, disconnected from any power source, and drained of all fluids before beginning any work. Wear appropriate personal protective equipment (PPE), including gloves and eye protection.
2. Access Components: Carefully disassemble the pump head to gain access to the diaphragms and valves. Note the orientation and position of all components as you remove them.
3. Remove Old Parts: Remove the worn diaphragms, valves, and O-rings. Inspect the pump housing for any damage or corrosion that might affect the new parts.
4. Install New Parts: Install the new diaphragms, valves, and O-rings from the repair kit. Ensure all components are seated correctly and O-rings are properly lubricated (if recommended by the pump's manual) to prevent leaks. Pay close attention to the specific diaphragm (1800.0034) and Buna diaphragms (1800.0012) placement.
5. Reassemble Pump: Reassemble the pump head, tightening fasteners to the manufacturer's specified torque settings. Incorrect torque can lead to leaks or damage.
6. Test Operation: After reassembly, slowly reintroduce fluid and pressure to the pump. Check for any leaks and observe the pump's operation to ensure it is functioning correctly.

If you are unsure about any step, it is recommended to consult a qualified technician or the official Comet service documentation.

5. Maintenance

The Comet APS145 Diaphragm Pump Repair Kit is a maintenance item designed to restore the performance of your pump. Diaphragms and valves are wear parts that degrade over time due to continuous operation, exposure to chemicals, and pressure fluctuations. Regular inspection and timely replacement of these components are critical for:

• Maintaining consistent pump pressure and flow rates.
• Preventing fluid leaks and contamination.
• Extending the overall lifespan of the pump.
• Ensuring safe and reliable operation.

It is advisable to establish a routine maintenance schedule based on your pump's usage intensity and the type of fluids being pumped. Replace components at the first sign of wear, such as reduced performance, visible cracks, or leaks.

6. Troubleshooting

If your Comet APS145 Diaphragm Pump exhibits issues after installing the repair kit, consider the following common troubleshooting steps:

• Leaks:
  • Ensure all O-rings are correctly seated and not pinched or damaged.
  • Verify that all fasteners are tightened to the correct torque specifications.
  • Inspect diaphragms for any tears or improper seating.
• Reduced Pressure/Flow:
  • Check if valves are installed in the correct orientation and are not obstructed.
  • Confirm diaphragms are properly installed and not damaged.
  • Inspect for air leaks in the suction line or pump housing.
• Unusual Noise:
  • Ensure all internal components are securely fastened and not loose.
  • Check for foreign objects within the pump chambers.

For persistent issues, consult the original pump manual or contact Comet technical support.
