12v Electric Self-Priming High-Pressure Diaphragm Booster Pump — Low-Noise Sprayer/Car Wash & Small Drone Accessory

Compact 12v diaphragm electric sprayer pump that combines the benefits of a self-priming unit and a chemical-resistant pump. Designed for low-noise operation, it functions as a booster pump for car wash systems and as an accessory for small drone sprayers. The pump features automatic on/off control — when the water outlet is closed the power is cut and the motor stops; opening the outlet restores power and the motor runs again. A built-in pressure switch provides automatic cutoff if the outlet pressure becomes too high. A rubber mounting bracket dampens vibration during operation. Intended for installation in a dry, well-ventilated location; not suitable for underwater use. Common applications include lawn and garden spraying, vehicle and ship cleaning, carpet and ground cleaning, and use in water purification and water treatment equipment.
