Mini Foam Pump

Mini Foam Pump Product Description
Product Overview
This DC 3.7V mini foam pump is a compact dual-purpose micro pump supporting both water pumping and air inflation. Designed with no-ear-style and ear-style liquid outlets, it features a lightweight integrated structure combining engineering plastic pump head, rubber sealing ring and stainless steel motor housing, delivering stable liquid & air output with low noise performance. Ideal for small portable appliances, foam dispensers, mini cleaning devices and small inflatable equipment.
Key Features
1. Dual-Function
Design Supports water pumping and air inflation two-in-one function, versatile for multiple small equipment applications.
2. Stable 3.7V DC Drive
Rated DC 3.7V working voltage, wide operating voltage range from 3.3V to 4.2V, compatible with common lithium battery power supply systems.
3. Excellent Fluid Performance
No-load water flow reaches ≥70mL/min; maximum output air pressure up to 26KPa, stable continuous output without pressure drop.
4. Low Noise Operation
Working noise ≤65dB under standard test conditions, quiet operation without harsh buzzing, suitable for household portable devices.
5. High Durability & Long Service Life
Passes 50,000 on-off cycle aging test; resistant to extreme temperature & humidity environments. Continuous long-hour operation will not cause motor overheating (max motor surface temperature below 60℃).
6. Reliable Sealing & Solid Structure
Built-in high-quality rubber sealing components to prevent liquid leakage. Stainless steel motor casing plus reinforced plastic pump head, anti-drop and anti-tensile wire terminals, strong mechanical stability.
7. Wide Adaptable Working Environment
Operates normally at 5℃~45℃ ambient temperature; storage range covers -20℃~60℃, adaptable for indoor and portable outdoor equipment.
