The DIANQI 12V DC 70W Sprayer Pump is a self-priming diaphragm pump designed for various applications including home boosting, garden sprinklers, car washing, and use in boats or RVs. It features a robust ABS and soft rubber construction for vibration isolation and includes overload and overheat protection for enhanced safety.
2. Safety Instructions
- Ensure the power supply matches the pump's voltage (DC 12V).
- Do not run the pump continuously for more than 6 hours to prevent overheating.
- Always disconnect power before performing any maintenance or installation.
- Ensure all connections are secure and watertight to prevent leaks and electrical hazards.
- Install a filter on the inlet side to prevent debris from entering and damaging the pump.
- Keep the pump body sealed to prevent moisture and dust ingress.
- This pump is designed for water transfer; do not use it with flammable or corrosive liquids.

4. Setup and Installation
- Identify Inlet and Outlet: Clearly distinguish the water inlet and outlet ports on the pump. The inlet typically has a filter recommendation.
Figure 2: Inlet and Outlet Identification
- Connect Pipes: Connect your water pipes to the inlet and outlet ports. Ensure all connections are tight and leak-free. The pump is designed for 20.6mm (0.81 inch) pipes. It is highly recommended to install a filter on the inlet pipe to prevent debris from entering the pump.
Figure 3: Typical Connection Diagram
- Mounting: The pump can be mounted above the water tank due to its self-priming capability. Use the integrated mounting feet to secure the pump to a stable surface.

5. Operating Instructions
- Initial Start-up: Once all connections are secure and the pump is properly positioned, apply power. The pump will self-prime and begin to draw water.
- Continuous Operation: The pump is designed for intermittent use. Do not operate the pump continuously for more than 6 hours to prevent motor damage from overheating.
- Adjusting Pressure: The pump's pressure can be slightly adjusted.
- To increase pressure, tighten the adjustment screw clockwise.
- To decrease pressure, loosen the adjustment screw counter-clockwise.

6. Maintenance
- Regular Inspection: Periodically check all pipe connections for leaks and ensure electrical wires are securely attached.
- Filter Cleaning: If an inlet filter is installed, clean it regularly to prevent clogging and maintain optimal pump performance.
- Wire Check: If the pump is not working, first check if the two wires behind the motor are loose. Re-secure them if necessary.
- Storage: If storing the pump for an extended period, especially in freezing conditions, drain all water from the pump and pipes to prevent damage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start or run. | No power, loose electrical connections, faulty power adapter. | Check power supply. Ensure red wire is positive and black is negative. Verify wires behind the motor are secure. Test power adapter. |
| Low flow or pressure. | Clogged inlet filter, air in the system, kinked hose, low voltage. | Clean inlet filter. Bleed air from the system. Check hoses for obstructions. Ensure stable 12V power supply. Adjust pressure screw. |
| Pump runs but no water flows. | No water in source, air lock, inlet pipe not submerged, faulty self-priming. | Ensure water source is available. Check for air leaks in inlet line. Ensure inlet pipe is fully submerged. |
| Excessive noise or vibration. | Loose mounting, air in pump, debris in pump. | Securely mount the pump. Check for air leaks. Inspect for debris (disconnect power first). |
| Pump overheats and shuts off. | Continuous operation for too long, restricted flow, high ambient temperature. | Allow pump to cool down. Do not run continuously for more than 6 hours. Check for blockages in pipes. Ensure adequate ventilation. |
