Hobbywing XRotor 30L Brushless Water Pump 12-18S, 20–30 L/min, PWM+CAN for Agriculture Drone

Overview

The Hobbywing XRotor 30L brushless water pump (flexible impeller type) is designed for large agriculture drones that need stable, high-flow liquid delivery. It supports 12–18S Li-Po power, delivers 20 L/min rated flow and up to 30 L/min max flow, while keeping weight to about 516 g. With integrated temperature and over-current protection, low vibration/low noise operation, and a sealed housing for harsh field environments, it’s a reliable choice for spraying systems that prioritize flow rate and durability.

Key Features

• High flow output: 20 L/min rated, up to 30 L/min maximum

• 12–18S wide-voltage input for large UAV spraying platforms

• Brushless long-life design: rated for 500+ hours (manufacturer statement)

• Protection built-in: temperature + current protection for safer operation

• Low vibration & low noise to reduce interference during field work

• Self-priming capability for more flexible tank and plumbing layouts

• Corrosion-resistant materials and simple structure for easier maintenance

Specifications

Control, Communication & Wiring

This pump system supports both PWM and CAN control, making it easy to integrate with UAV sprayer controllers.

Cable (typical harness): 180 mm, 6-core silicone wire with terminals
Wire color reference: GND (Yellow), S (Purple), CH (Blue), CL (Green), + (Red), – (Black)

If you want help matching this pump to your flight controller/sprayer controller (PWM mapping or CAN integration), contact us and we’ll help you confirm the wiring and control settings before shipping.

Plumbing & Installation Notes

• Ports are clearly marked IN/OUT; use hose sized for 20.53 mm OD fittings (recommended 19 mm ID hose).

• Self-priming helps when the pump mounting position is constrained by tank structure.

• Important nozzle requirement: this is a non-pressure pump and is intended to be used with centrifugal nozzles. It is not compatible with pressure-type spray nozzles that require pump pressure.

Fluid Compatibility for Agriculture Spraying

Designed for common agrochemical spraying mixtures, including:

• Water-based solutions

• Emulsifiable concentrates

• Suspension concentrates

For best reliability, always flush the system after use and confirm chemical compatibility with your specific formulation and hose materials.

Applications

• Large agriculture drone spraying systems

• High-flow pesticide/fertilizer liquid delivery lines

• UAV liquid circulation and transfer in agricultural payload modules
