Why Choose DC50G For Reef & Planted Aquariums

1. Ultra quiet performance under 40dB No more loud buzzing from old AC pumps in your living room. The brushless magnetic isolated design reduces vibration and noise, perfect for display reef tanks.
2. Customizable flow with PWM speed control Tweak water circulation precisely. Reduce flow for delicate coral or planted tanks, boost flow for large reef sumps. It supports potentiometer manual adjustment too.
3. Critical safety protection for aquarium systems Dry-run protection automatically protects the pump when water level drops, preventing pump burnout and tank disaster. Soft start avoids current shock for long-term reliability.
4. IP68 waterproof & long service life IP68 rating means it can run fully submerged in sump chambers. Ceramic shaft construction delivers more than 30,000 working hours with zero routine maintenance.
5. Flexible power supply 12V and 24V options work with adapters, batteries or solar panels. Solar compatibility makes DC50G a great emergency backup pump during power outages.

DC50G Installation & Wiring Tips

1. The DC50G can be submerged or mounted inline on dry land. Remember it is NOT self-priming. Fill the pipeline with water before dry-land running.
2. 1/2 inch M20 threaded ports fit standard aquarium pipe fittings.
3. Potentiometer speed wiring: Red and black wires to potentiometer two ends, yellow wire connects to the middle pin to adjust flow.
4. PWM / 0-5V VR control: Yellow wire for signal output, black wire to ground; leave red wire unconnected.
5. Important note: Max flow rate only happens at zero lift. Flow volume will drop as vertical lift height increases, calculate your tank total head before purchase.
