- Uses domestic Perx AYL pump tube (life 1000H).
- Optional pump tube sizes (04#, 06#, 10#) to meet different flow requirements.
- 3-roller pulse moderate design.
- Through-plate fixing installation method with quick-release pump head.
- Transmission mode: gear transmission, first-stage reduction ratio 1:14.
- Suitable for pump tubes with wall thickness 1.0.
2. Setup Instructions
2.1 Unpacking and Inspection
Carefully unpack the pump and inspect for any visible damage. Ensure all components listed in the packing list are present:
- 1 × Kamoer KEF Peristaltic Pump (12V or 24V, depending on model)
- 1 × Silicone tube (e.g., S10: Silicone 3.0*5.0 mm for 12V model)
2.2 Connecting Silicone Tubing
Connect the silicone tubing to the pump head's inlet and outlet ports. Ensure a snug fit to prevent leaks.
2.3 Power Connection
Identify the positive ("+") and negative ("-") terminals on the pump motor. The red side is typically positive, and the other side is negative. Connect your power adapter or DC power source accordingly.
Important: According to the motor wiring diagram (refer to the official PDF manual), the positive pole of the power supply should be connected to the positive pole and the negative pole should be connected to the negative pole.

Refer to Video 1 for a visual guide on connecting the power adapter and observing the pump in operation.
3. Operating Instructions
3.1 Basic Operation
Once the tubing and power are connected, apply the rated DC voltage (12V or 24V, depending on your pump model) to the pump. The pump will begin to transfer liquid. Ensure the pump tube inlet is completely submerged in the liquid to ensure proper absorption.
3.2 Controlling Flow Direction
The flow direction of the liquid can be changed by reversing the polarity of the power connection to the motor. If the liquid is flowing in the undesired direction, disconnect the power, swap the positive and negative connections, and then reapply power.
Video 1 demonstrates how reversing the "+" and "-" connections changes the direction of flow.
4. Maintenance
4.1 Pump Tube Replacement
The pump head is designed for quick release, making tube replacement straightforward. Regularly inspect the pump tube for wear, cracks, or hardening, especially if transferring aggressive liquids. Replace the tube as needed to maintain optimal performance and prevent leaks.
The pump uses domestic Perx AYL pump tubes, with a typical life of 1000 hours. Ensure replacement tubes match the original specifications (e.g., 3mm ID × 5mm OD for the 85ml/min model).
4.2 General Cleaning
Keep the exterior of the pump clean and free from dust and debris. If liquid spills occur, wipe them immediately. Do not immerse the pump in water or other liquids for cleaning.
5. Troubleshooting
- No Flow or Reduced Flow:
- Check power connections and ensure correct voltage is applied.
- Verify the pump tube is not kinked, blocked, or worn out.
- Ensure the pump tube inlet is fully submerged in the liquid.
- Inspect for air bubbles in the tubing, which may indicate a loose connection or an empty reservoir.
- Incorrect Flow Direction:
- Reverse the polarity of the power connections to change the flow direction.
- Hose Damage or Leakage:
- Improper hose selection or chemical incompatibility with the liquid media can cause rapid hose damage. Always check chemical compatibility or conduct an immersion test if unsure.
- Liquid leakage accidents caused by hose rupture depend on the liquid medium and your specific application conditions. Regular inspection and timely replacement of the pump tube are crucial.
- Premature Product Damage:
- Operating the pump in a bad working environment (e.g., exceeding 45°C temperature or 70% humidity, non-condensing) can lead to premature damage.
- High overload work may also cause premature damage. Ensure the pump is used within its specified operating parameters.
