Mini DC Water Pump 5-9V (Non-Submersible)

Mini DC Water Pump 5-9V (Non-Submersible) Overview

The Mini DC Water Pump 5-9V (Non-Submersible) is a compact, efficient pump designed for low-pressure water transfer in DIY, electronics, hobby, and educational projects. Operating on a 5V to 9V DC range, this non-submersible pump draws liquid through an inlet tube and delivers steady flow through an outlet. Its small footprint and lightweight plastic body make it easy to integrate into automated plant watering, desktop fountains, and water-cooling setups.

Key Features

• Operating voltage: 5V to 9V DC for flexible power options
• Non-submersible configuration so the unit remains outside the water source
• Compact plastic housing that is lightweight and easy to mount
• Low power consumption and quiet DC motor suitable for indoor use
• Simple electrical connections for quick integration with microcontrollers
• Moderate flow rate suitable for small-scale circulation and transfer tasks

Specifications

• Operating Voltage: 5V to 9V DC
• Material: Plastic housing
• Pump Type: Non-submersible
• Flow Rate: Moderate, varies by applied voltage and tubing diameter
• Use Case: Indoor use only
• Motor: DC motor designed for low noise and energy-efficient operation

Common Applications

• Automated plant watering and hydroponic micro-systems
• Miniature water circulation in desktop fountains and displays
• Water cooling for small electronics and hobby projects
• Science experiments and educational demonstrations
• Prototype fluid-control systems for robotics and IoT projects

Installation and Microcontroller Integration

This non-submersible pump is easy to wire and control. It can be powered directly from a regulated 5V or 9V supply. For microcontroller control, use a transistor, MOSFET, or relay to switch the motor, and include a diode for back-emf protection. The pump works well with Arduino and Raspberry Pi when paired with an appropriate driver or motor controller board.

• Recommended: use a separate power supply for the pump to avoid noise on microcontroller rails.
• Use tubing that matches the inlet/outlet diameter to maintain optimal flow.
• Include a flyback diode or snubber when switching the motor electronically.

Tips, Safety, and Maintenance

• Priming: Fill the inlet tube with water before starting to reduce dry-run wear.
• Cleaning: Flush the pump with clean water periodically to avoid blockages.
• Indoor use only: avoid exposure to outdoor weather and freezing conditions.
• Do not submerge the pump body in liquid; keep the unit outside the water source as intended.
• Check voltage and polarity before connecting to prevent motor damage.

Why Choose This Mini Water Pump

The Mini DC Water Pump 5-9V (Non-Submersible) provides a reliable, quiet, and energy-efficient solution for small water transfer tasks. Its compatibility with Arduino and Raspberry Pi and straightforward installation make it a favorite for makers, students, and hobbyists building automated watering systems, small cooling loops, or demonstration models.
