viwomik DC 12V Submersible Water Pump 800L/h 5M Head Brushless Low Noise for Aquarium, Solar Fountain, Cooling System, Water Circulation

Product Description (Key Selling Points & Specs):

DC 12V Submersible Water Pump — 800L/h 5M Head Brushless Low Noise for Aquarium, Solar Fountain, Cooling System!

This brushless submersible pump offers reliable, quiet water circulation for a wide range of applications. With 800L/h flow rate and 5M max head, it's perfect for aquariums, solar fountains, cooling systems, and irrigation. The brushless motor runs quietly (below 35dB) and lasts over 10,000 hours. IP68 waterproof design allows full submersion.

Why Choose This Submersible Pump?

Brushless Motor & Long Lifespan: Carbon-free, electronic commutation design — no pollution, low wear. Lifespan exceeds 10,000 hours.

Ultra-Low Noise (<35dB): Quiet operation — won't disturb your home, office, or fish.

IP68 Waterproof Fully Submersible: Complete waterproof seal — safe for underwater installation. Epoxy resin potting isolates motor and circuit board for long-term submersion.

High Flow & Head: 800L/h max flow rate with 5M max static head — efficient water circulation for various applications.

Wide Voltage Compatibility: DC 7-14V input — works with solar panels, battery, adapters, and power modules.

Durable Corrosion-Resistant Materials: ABS housing, zirconia ceramic rotor shaft, and POM components — wear-resistant, corrosion-resistant, and built to last.

Anti-Vibration Silicone Base: Optional silicone pad absorbs vibration — reduces noise and ensures stable operation.

Wide Application: Suitable for aquariums, solar fountains, cooling systems, irrigation, water circulation, and more.

Important Usage Notes:

This pump is a submersible centrifugal pump. It must be placed underwater, or when connected to a pipeline, the water source level must be lower than the pump inlet so that air can be expelled from the pump chamber before normal operation begins.

When selecting this pump, please specify the usage conditions — operating time, water temperature, medium type, etc. For pumps above 24W, continuous operation in water temperatures above 65°C is not recommended. Consult a professional to ensure you choose the most suitable model.

The specified current is the open-flow current (pump operating without any system restriction). This is the maximum current. When connected to a system, the working current will drop to 70%-85% of the maximum load current.

The max head is the maximum water lift height — flow rate is zero at this point.

The max flow rate is measured under horizontal pumping conditions.

Do not run this pump dry for extended periods.
