Introduction
This manual provides essential information for the safe and efficient operation of your Hobbywing 5L or 8L Brushless Water Pump Head. Designed for agricultural UAV drones, this sprayer diaphragm pump is a critical component for precise liquid application. Please read this manual thoroughly before installation and use.
Product Overview
The Hobbywing Brushless Water Pump Head is available in two main variants: 5L and 8L, referring to their nominal flow rates. These pump heads are designed for integration into agricultural UAV drone spraying systems. They feature a robust nylon construction and are available with either threaded or barbed connectors to suit various plumbing setups.

Setup
- Mounting: Securely mount the pump head to the designated location on your UAV drone. Ensure it is stable and free from excessive vibration. Use appropriate fasteners that do not overtighten or damage the pump housing.
- Plumbing Connections:
- For Threaded Connectors: Apply thread sealant tape (PTFE tape) to the threads of your inlet and outlet hoses. Carefully screw the hoses into the pump head connectors, ensuring a tight, leak-free seal. Do not overtighten.
- For Barbed Connectors: Slide the appropriate size tubing over the barbed connectors. Use hose clamps or zip ties to secure the tubing firmly to prevent leaks and accidental disconnection during flight.
- Electrical Connection: Connect the pump head's power leads to your drone's power distribution board or ESC (Electronic Speed Controller) that is capable of providing 10A current and up to 14S voltage. Ensure correct polarity (positive to positive, negative to negative) to prevent damage. Refer to your drone's wiring diagram for specific connection points.
- Initial Check: Before applying power, double-check all connections (mechanical and electrical) for security and correctness.
Operating Instructions
- Priming (if necessary): Depending on your system design, you may need to prime the pump by ensuring the inlet line is submerged in liquid and there are no air pockets before initial operation.
- Power On: Apply power to the drone system. The pump should remain off until activated by the flight controller or a dedicated switch.
- Activation: Activate the pump via your drone's flight control software or remote control. Start with a low flow rate if adjustable, and gradually increase to the desired output.
- Monitoring: During operation, monitor the pump's performance, checking for consistent flow and any unusual noises or vibrations.
- Power Off: Deactivate the pump before powering down the drone system.
Maintenance
- Regular Cleaning: After each use, especially when spraying agricultural chemicals, flush the pump and lines with clean water to prevent residue buildup and corrosion.
- Inspect Connections: Periodically check all plumbing and electrical connections for leaks, corrosion, or wear. Tighten or replace as necessary.
- Diaphragm Inspection: While the pump head is designed for durability, inspect the diaphragm for any signs of wear, cracking, or damage if you experience reduced performance. Replacement of the pump head may be necessary if the diaphragm is compromised.
- Storage: When not in use for extended periods, ensure the pump is clean and dry. Store in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on | No power, incorrect wiring, faulty switch/controller | Check power supply, verify electrical connections and polarity, test switch/controller. |
| No flow or weak flow | Air in lines, clogged inlet/outlet, kinked hose, damaged diaphragm | Bleed air from system, clear obstructions, straighten hoses, inspect diaphragm for damage. |
| Leaking from connections | Loose connections, damaged seals/tape, incorrect hose size | Tighten connections, reapply thread sealant, replace hose clamps, ensure correct hose fit. |
| Unusual noise/vibration | Loose mounting, foreign object, internal damage | Check mounting screws, inspect for debris, if noise persists, pump may require replacement. |
User Tips
- Always use clean water for flushing after spraying to extend the pump's lifespan.
- Ensure your power source (battery/ESC) can consistently deliver the required 10A current for optimal pump performance.
- Consider using a filter on the inlet line to prevent particles from entering and damaging the pump head.
Safety Information
- Electrical Safety: Always disconnect power before making any electrical connections or performing maintenance. Incorrect wiring can cause damage to the pump, drone, or pose a fire hazard.
- Chemical Handling: When using the pump with agricultural chemicals, always follow the chemical manufacturer's safety guidelines. Wear appropriate personal protective equipment (PPE).
- Water/Liquid: Ensure the pump is only used with liquids it is designed for. Do not run the pump dry for extended periods, as this can cause damage.
- Children and Pets: Keep the pump and associated chemicals out of reach of children and pets.
