DC 3.7V Micro Peristaltic Dosing Pump | 10mm Planetary Gear
DC 3.7V Micro Peristaltic Dosing Pump | 10mm Planetary Gear
DC 3.7V Ultra Micro Peristaltic Pump with 10mm Planetary Gear Motor
This ultra-compact micro peristaltic pump delivers exceptionally precise, low-flow fluid metering in a tiny 11.7 × 14.5 × 31.8 mm package. Driven by a miniature M20 10mm planetary gear motor, it is ideal for laboratory analyzers, sampling instruments, portable biochemical devices, and electronic equipment requiring accurate dosing control.
Key Features
- Detachable Pump Head: The precision-cast metal pump head separates cleanly from the motor for easy maintenance, tube replacement, and cleaning.
- Metal Construction: Both the pump body and the three internal rollers are precision-cast metal, ensuring durability and consistent performance.
- Voltage-Adjustable Flow Rate: Fine-tune your flow by adjusting the voltage — approximately 1 drop per 2 seconds at DC 2.4 V and 1 drop per second at DC 4.2 V (≤ 1 mL/min max).
- Ultra-Low Power Draw: Operating current of only 30–38 mA makes it perfect for battery-powered and portable devices.
- Compact & Lightweight: The tiny footprint (11.7 × 14.5 × 31.8 mm) fits into the tightest enclosures and project builds.
- Broad Voltage Compatibility: Rated at DC 3 V–3.7 V, with an applicable range of DC 2.4 V–4.2 V.

Frequently Asked Questions
Q: What voltage should I use to run this micro peristaltic pump?
A: The rated operating voltage is DC 3 V–3.7 V, but the pump operates across a wider range of DC 2.4 V–4.2 V. Adjusting the voltage within this range lets you fine-tune the flow rate — lower voltage gives a slower drip, higher voltage speeds it up.
Q: Can the pump head be removed and cleaned separately?
A: Yes. The precision-cast metal pump head detaches from the motor body independently, making tube replacement, cleaning, and maintenance straightforward without disturbing the motor.
Q: What is the maximum flow rate of this micro dosing pump?
A: The maximum flow rate is ≤ 1 mL/min. At DC 2.4 V it produces approximately 1 drop every 2 seconds, and at DC 4.2 V approximately 1 drop per second, making it ideal for precision micro-dosing applications.
Q: Is this pump suitable for Arduino or microcontroller projects?
A: Absolutely. Its low operating current (30–38 mA), compact size, and wide voltage range make it an excellent choice for Arduino, Raspberry Pi, and other microcontroller-based DIY electronics and lab automation projects.
