Small DC 12V Diaphragm Air Pump (DC Brush motor)

**Air Pump / Vacuum Pump / DC Pump (Diaphragm Pump)** **Product Description:** TOPSFLO micro diaphragm pumps and compressors operate on a simple principle: the rotational power from the motor is converted into oscillating movement by an eccentric. This motion is then transferred to a diaphragm via a connecting rod, creating a pumping action when combined with inlet and outlet valves. These pumps are designed for precision, reliability, and quiet operation, making them ideal for a wide range of industrial and medical applications. **Technical Features:** 1. High performance-to-size ratio 2. Quieter operation compared to traditional pumps 3. Longer lifespan and reliable performance 4. Uncontaminated flow, ensuring clean output 5. Minimal vibration and noise 6. Excellent gas tightness 7. Strong chemical resistance 8. Customizable for specific application needs **Applications:** TOPSFLO pumps are widely used in various fields, including: - Industrial pressure and vacuum systems - Portable analytical instruments - Medical diagnostic equipment - Air quality sampling monitors - Respiration monitoring systems - Gas or odor leak detectors **Motor Options:** Our micro diaphragm pumps come with four different drive motor options: **A - Premium Duty Brush DC Motor** - Lifetime: > 5,000 hours - Offers longer endurance than standard DC membrane pumps **B - Economical Brush DC Motor** - Lifetime: 1,500 hours - Cost-effective solution for basic applications **C - Coreless Brushless DC Motor** - Vibration and spark-free operation - Extremely durable with a life expectancy of 15,000 hours - Ideal for high-performance environments **D - Coreless Brushless DC Motor with External Controller** - Combines all benefits of the coreless brushless motor - Enables advanced control features such as PWM, 0–5V speed adjustment, braking, and instant start-up - Perfect for custom automation setups **H - Brushless DC Motor** - Long life: 10,000 hours - Suitable for continuous operation in demanding conditions **Package & Specifications:** - Pump Weight: 220g - Dimensions: 80mm x 30.5mm x 59mm - Inlet/Outlet: OD 4.9mm / ID 2.8mm - Recommended Hose: ID 4.0mm - Noise Level: < 50dB at 1 meter - Materials: Pump head (Nylon), Membrane (EPDM/PTFE), Valve (EPDM/FPM) **Model: TM30B-A** - Rated Voltage: 6/12/24V - No-load Current: 0.4/0.24/0.15A - Max Pressure: 100kPa - Max Vacuum: -55kPa - Max Flow: 5L/min **Note:** "**P**" stands for pressure pump, "**V**" for vacuum pump, and "6/12/24" indicates available voltage options. **Why Choose TOPSFLO?** TOPSFLO is a leading manufacturer of high-quality diaphragm pumps, known for their durability, efficiency, and innovation.
