Hobbywing 8L Water Pump Spray System with Pressure Nozzles

A complete spray set for agricultural drones built around Hobbywing's 8L brushless water pump, the higher-flow sibling of the 5L pump. Four EFT extension-rod high-pressure nozzles, tubing and push-fit connectors come with it, so a 12–14S spray airframe can be plumbed from one box.

Key features

• Up to 8 L/min from a brushless pump with its ESC built in, controlled by a PWM channel from the flight controller
• Runs straight off the 12–14S flight battery (DC 44–60.9 V) — no separate regulator or speed controller
• Over-current protection for blocked lines and thermal shutdown at 110 °C
• IP67 pump housing that can be rinsed clean after spraying to limit chemical corrosion
• Four EFT extension-rod high-pressure nozzles with 5 m of tubing in two sizes and six pneumatic connectors

Specifications

• Pump flow: up to 8 L/min
• Operating voltage: 12–14S LiPo (DC 44–60.9 V)
• Throttle signal: PWM, 1050–1950 µs
• Protection: IP67
• Pump size: approx. 140 × 95 × 70 mm
• Pump weight: approx. 690 g
• In the box: 1 × 8L brushless water pump, 4 × EFT extension-rod high-pressure nozzles, 1 × 4 m tube (5 × 8 mm), 1 × 1 m tube (8 × 10 mm), 6 × pneumatic tube connectors

Hobbywing positions the 8L pump for 20–30 L class spray drones; smaller tanks and booms are better matched to the 5L version of this kit.
