Vertical Mute Sounds 80-100L/H Mini Submersible Pump DC 3V-5V

Vertical Mute Sounds 80-100L/H Mini Submersible Pump DC 3V-5V offers an exceptionally compact and quiet solution for fluid transfer in small-scale projects. Designed to operate efficiently within a low-voltage range of 3V to 5V DC, this pump is perfectly compatible with common power sources like USB ports, power banks, and microcontroller boards such as Arduino or Raspberry Pi. Its submersible nature makes it ideal for tasks requiring water circulation, cooling, or controlled flow, delivering a steady rate of 80 to 100 liters per hour (L/H). Hobbyists and designers frequently integrate this miniature pump into desktop fountains, pet water dispensers, and specialized cooling systems where noise reduction is a critical factor.

Key Features:

• Ultra-Low Noise Operation: Engineered with a magnetic drive and mute technology, the pump generates minimal sound, making it suitable for indoor and quiet environments.
• Wide Operating Voltage: Works reliably across a DC range of 3V to 5V, providing flexibility for power supply options, including 5V USB power.
• Submersible Design: Constructed for full immersion in water, ensuring direct, efficient fluid intake and transfer.
• High Flow Rate for Size: Achieves a powerful flow of 80-100 L/H despite its miniature footprint.
• Long-Life Performance: Utilizes a brushless design that minimizes wear and tear, extending the operational life of the unit.
