Hobbywing 5L Brushless Water Pump - IP67 12S-14S Integrated High Flow Diaphragm Pump for Agricultural Spraying Drones
The Hobbywing 5L Brushless Water Pump sets an industrial benchmark for fluid delivery systems within modern plant protection unmanned aviation. By utilizing an advanced brushless outrunner configuration instead of low-life traditional brushed motors, this integrated diaphragm pump achieves an operational lifespan up to 5 times longer than legacy components.Encased in a completely sealed waterproof housing, it carries a built-in smart electronic speed controller (ESC) that regulates high-pressure fluid flow seamlessly via standard PWM signals.This makes it an invaluable asset for commercial operators who require even distribution, zero chemical back-bleeding, and lower maintenance overhead during large-scale seasonal agricultural sweeps.
Key Features :
Extended Brushless Lifespan:Rated for over 500 hours of continuous field operation, eliminating early mechanical pump decay and frequent bench rebuild costs.
Double Smart ESC Safeguards:Features autonomous temperature and overcurrent protection that auto-disconnects above 110°C to eliminate overheating damage.
IP67 Ruggedized Ingress Rating:Completely waterproof, dust-resistant, and chemically shielded, allowing operators to safely pressure-wash the frame after chemical use.
Precision Linear PWM Control:Natively operates over a 1050–1950μS bandwidth to deliver immediate variable flow tracking based on flight ground speeds.
Use Cases :
High-volume primary liquid delivery and atomized spraying systems for 10L to 16L agricultural multirotor platforms.
Nutrient solution transport and continuous fluid circulation loops in commercial hydroponic or vertical farming installations.
Custom high-voltage liquid distribution systems for industrial automation, remote cleaning, and automated ground vehicles.

Compatibility Information :
This integrated brushless pump drops cleanly into professional drone flight environments. The control leads link natively to custom or open-source flight controllers like JIYI K3A Pro, K++, Pixhawk, and standard industrial autopilots running custom output mappings. Its high-voltage power lines attach seamlessly to standard PDBs or 12S–14S drone smart batteries, and the barb ports accept standard heavy-wall silicone or PVC agricultural tubing lines.
Frequently Ask Questions :
Q1 ) What structural benefits does the brushless technology bring over old brushed water pumps?
Ans : Traditional brushed pumps face friction wear from carbon brushes, limiting life to ~100 hours. Hobbywing's brushless motor removes physical contact points, pushing the continuous service envelope past 500+ hours while running cooler and consuming less current.
Q2 ) What additional accessories do I need to provide to make this pump assembly operational?
Ans : The factory box comes loaded with the core 5L pump module and basic structural fitting accessories.To establish full operation, you must provide your own 12S–14S power link, a flight controller or PWM signal generator, and matching 10.5mm/6.5mm fluid hoses.
Q3 ) Can I use standard cyanoacrylate CA glues to secure the fluid barb fittings?
Ans : No, standard rigid super glues will crack under the high-frequency vibrations produced by the interior diaphragm engine. It is highly recommended to use clean zip-ties or metal spring tension clips over the hosing walls to secure connections without chemical degradation.
Q4 ) What voltage range does this pump support?
Ans : The Hobbywing 5L pump handles a broad high-voltage window ranging from 12S to 14S LiPo setups, translating to a direct current (DC) scale spanning 44V up to 60.9V.Do not use low-voltage 3S–6S batteries, as the internal speed controller will not boot up.
Q5 ) Which tubing sizes fit the inlet and outlet ports accurately?
Ans : The physical barb architecture features a 10.5 mm diameter fluid inlet port and a 6.5 mm diameter outlet port.To ensure zero pressurized liquid leaks, pair the module with flexible silicone or reinforced PVC hoses matching these exact inner dimensions.
