GDB-280 Mini Diaphragm Pump – Quiet, Self-Priming & Ready for Your Project

Finally: A Tiny Pump That Doesn’t Quit

You’ve tried cheap pumps. They buzz. They leak. They die after 3 weeks. The GDB-280 is different. It’s the quiet, reliable, no-nonsense diaphragm pump built for real projects — whether you're upgrading a coffee machine, building a self-watering planter, or fixing a soap dispenser. No priming needed. Low noise. Tested for over 10,000 on/off cycles — designed to last **months of regular use**, not just days.

Why Makers Love This Pump

✅ Whisper-Quiet Operation
At ≤50dB (less than a refrigerator), it won’t disturb your sleep or office work.

✅ Self-Priming – No Mess, No Wait
Turn it on, and it starts pumping immediately — no need to pour water in first. Suction lift up to 1 meter.

✅ Built to Last (Not Just Break)
Tested for over 10,000 cycles (30 seconds on / 30 seconds off). That means if used 10 times per day, it can last **over 2 years**. Real-world lifespan depends on liquid type and operating conditions.

✅ Safe with Mild Liquids
Works with clean water, weak acids, and salt solutions — ideal for cleaning devices, misters, or lab kits.

✅ Ultra Compact & Low Power
Only 7cm long. Uses as little power as an LED bulb (2.5W). Perfect for battery or solar-powered projects.
