5. Operating Instructions
5.1 Basic Operation
Once the power cable is connected correctly, the pump will run at full speed at its rated voltage. The peristaltic design ensures that the liquid does not contact the pump itself, preventing pollution and making it suitable for sensitive liquids.

5.2 Flow Direction (Positive Inversion)
The pump features positive inversion, meaning it can dry-run and is self-priming. It also includes a stop valve function to prevent backflow in both directions. The flow direction can be reversed by swapping the positive and negative power connections.

5.3 Noise Level
The Kamoer NKP pump operates at an ultra-silent level, typically less than 40dB, making it suitable for noise-sensitive environments.

6. Maintenance
The Kamoer NKP pump is designed for low maintenance. The primary maintenance task involves changing the tubing.
6.1 Tube Replacement
- Disconnect the pump from its power source.
- Locate the buckle joint on the pump head.
- Carefully unclip the buckle joint to open the pump head.
- Remove the old tubing.
- Insert the new tubing, ensuring it is properly seated within the pump head.
- Close the buckle joint securely.
Regular inspection of the tubing for wear and tear is recommended, especially for silicone tubes which have a shorter lifespan compared to BPT tubes.

7. Troubleshooting
- Pump not running:
- Check power connections for correct polarity (+/-).
- Ensure the power supply voltage matches the pump's rated voltage (6V, 12V, or 24V).
- Verify the power source is active.
- No liquid flow or reduced flow:
- Check for kinks or blockages in the tubing.
- Ensure the tubing is correctly installed in the pump head.
- Inspect tubing for wear, cracks, or damage; replace if necessary.
- Verify the liquid source is not empty.
- Confirm the suction side of the tube is submerged in the liquid.
- Excessive noise:
- Ensure the pump is securely mounted.
- Check for any foreign objects obstructing the pump mechanism.
8. User Tips
- For applications requiring precise dosing or handling sensitive liquids, consider using BPT tubing due to its longer lifespan and chemical resistance.
- When setting up, ensure the inlet tube is fully submerged in the liquid to prevent air intake and ensure consistent flow.
- The compact size of the pump (65mm x 48.5mm) allows for integration into various small-scale systems, such as aquariums or laboratory setups.
- The "Zero pollution, low pulse" design makes it ideal for applications where liquid purity and gentle transfer are crucial.
