AD20P-1230C Ultra-Quiet DC 12V 3M 240L/H Brushless Submersible Water Pump

AD20P-1230C Ultra-Quiet DC 12V 3M 240L/H Brushless Submersible Water Pump offers a perfect solution for projects requiring reliable, low-noise water circulation. This compact pump leverages brushless DC motor technology, which eliminates brush friction, significantly reducing operational noise and extending the service life far beyond that of conventional brushed pumps. Operating efficiently on a safe 12V DC power supply, it generates a maximum lift (head) of 3 meters and moves water at a consistent rate of up to 240 liters per hour (L/H). Its fully submersible design and durable construction allow it to handle continuous operation in various fluid-transfer applications, from small fountains and aquariums to solar thermal systems. You can count on this pump to deliver consistent flow with minimal acoustic interference.

Key Features:

• Brushless Motor Technology: Ensures ultra-quiet operation, high efficiency, and a significantly extended product lifespan.
• High Lift Capability: Generates a maximum head of 3 meters (9.8 feet), suitable for lifting water to moderate heights in various setups.
• Energy Efficient: Runs on a safe, low-voltage 12V DC supply, consuming minimal power during continuous operation.
• Fully Submersible: Designed for continuous use entirely immersed in water, ideal for wet environments.
• Ceramic Rotor: Uses a durable ceramic shaft and rotor for superior wear resistance and magnetic isolation from the motor coils.

Commonly Used in:

• Aquarists and Hobbyists: Essential for small to medium-sized fish tanks and hydroponic systems.
• Engineers and DIY Enthusiasts: Integral part of custom cooling systems and fluid transfer projects.
• Small Solar Systems: Circulating water in compact solar water heaters or small pond aeration systems.

Applications:

• PC Water Cooling Systems: Moving coolant efficiently through CPU or GPU blocks to maintain optimal temperatures.
• Pet Drinking Fountains: Ensuring continuous, fresh, and quiet water circulation.
• Hydroponics and Aquaponics: Circulating nutrient solutions to plant roots with low power draw.
• Decorative Fountains: Creating small waterfalls and fountain features with minimal ambient noise.

Equivalent Models:

• Mini Submersible Brushed Pump: Lower-cost alternative, but offers less lifespan and higher noise levels.
• 5V USB Mini Pump: Offers similar flow but requires a 5V source and provides significantly less head/lift.
• Higher Flow Brushless Pump (e.g., 500 L/H): Used when a greater flow rate is necessary, usually consuming more power.

Package Includes:
