The 3V–3.7V Micro 310 Water Pump is a compact, high-efficiency diaphragm pump designed for precise liquid handling. At Electrapac, we recommend this module for its self-priming capability, making it an excellent choice for automatic water dispensers, DIY beverage machines, and medical or lab equipment prototypes.

Product Overview

Driven by a reliable 310-series carbon brush motor, this micro pump utilizes a diaphragm mechanism to create a vacuum, allowing it to draw water from a source without manual priming. Its low voltage requirement makes it perfectly compatible with single-cell Lithium-ion batteries (3.7V) or USB power sources.

Key Features for Electrapac Customers

• Self-Priming Capability: Unlike standard centrifugal pumps, the 310 diaphragm pump can lift water from a lower level automatically, ensuring consistent flow even after a dry start.

• Battery Optimized: Specifically tuned for 3.7V Lithium batteries, making it ideal for portable, handheld, or battery-operated electronics.

• Quiet and Delicate: Designed for low noise and minimal vibration, which is crucial for desktop appliances like tea table dispensers or humidifiers.

• Compact Mounting: Many variants feature "mounting ears" or a slim 27mm diameter, allowing for easy installation in tight enclosures or project boxes.

• Durable Engineering: Built with high-quality engineering plastics and metal components to resist wear and tear during continuous operation.

Wiring & Connection Guide

For the best results with your purchase from www.electrapac.com, follow these steps:

1. Power Input: Connect the red wire to (+) and the black wire to (-). Reversing the wires will change the motor's spin but may not reverse the water flow effectively due to the internal valves.

2. Tubing: Use standard flexible silicone tubing (typically 4mm inner diameter). Ensure the connections are airtight to maintain suction pressure.

3. Filtration: It is highly recommended to use a small filter on the inlet tube to prevent debris from clogging the delicate diaphragm valves.

Primary Applications

• Water Dispensers: Automatic tea machines, coffee makers, and smart water bottles.

• DIY Hygiene: Automatic hand sanitizer or soap dispensers (liquid type).

• Hobbyist Robotics: Plant watering systems using Arduino or ESP32 moisture sensors.

• Medical Prototyping: Small-scale fluid transfer and sampling devices.
