Short Product Description

Looking for precise liquid control for your next engineering or STEM project? The Micro 370 DC12V Water Pump is a highly versatile, self-priming diaphragm pump designed for reliability and low-noise operation. Featuring a built-in induction flow meter, it delivers accurate fluid measurement in a compact 82g footprint. Whether you are building an automated hydroponics system, upgrading a medical device, or creating a DIY smart liquid dispenser, this mini pump provides the consistent performance and durability that professional makers and engineers demand.

Key Features

  • Integrated Induction Flow Meter: Allows for precise measurement and programmatic control of liquid volume via microcontrollers.
  • Self-Priming Capability: Eliminates the need for manual priming or submersion, offering flexible installation options above fluid reservoirs.
  • Low-Noise 370 Motor: Operates quietly, making it suitable for noise-sensitive environments like offices, labs, or home automation setups.
  • Dual Functionality: Acts reliably as both a fluid transfer water pump and a mini vacuum pump for air/gas extraction.
  • Energy Efficient: Draws only 0.15A at 12V, making it ideal for battery-operated STEM projects or mobile robotics.
  • Standardized 6.4mm Ports: Ensures hassle-free connection with widely available silicone tubing for leak-proof fluid paths.

Full Product Description

Precision Fluid Control for Professional and DIY Projects

When your project requires accurate liquid transfer, standard hobby pumps often fall short. The Micro 370 DC12V Water Pump bridges the gap between consumer DIY components and industrial hardware. Engineered with a robust 370 motor, this pump delivers consistent pressure while maintaining an impressively low noise profile, making it ideal for indoor, desktop, or laboratory environments.

 

Why Choose a Self-Priming Diaphragm Pump?

Unlike centrifugal pumps that must be submerged, this self-priming diaphragm pump can pull liquids from a lower level without needing manual priming. This capability makes it incredibly versatile, functioning seamlessly as both a water pump and a mini vacuum pump. Its dry-run tolerance ensures the motor won't immediately burn out if your fluid reservoir runs dry, giving you peace of mind during automated operations.

 

Built-in Induction Flow Meter for Smart Applications

What sets this unit apart is its integrated induction flow meter. Instead of guessing the volume of liquid dispensed, you can interface the sensor data directly with microcontrollers like Arduino or Raspberry Pi. This enables closed-loop feedback systems, allowing you to program exact dosage amounts for beverage dispensers, scientific equipment, or automated plant watering systems.

 

Designed for Easy Integration

We understand that hardware integration should be straightforward. With standard 6.4mm outer diameter inlet and outlet ports, connecting standard silicone tubing is quick and secure. Operating on a wide voltage range of DC 7.4V to 12V with a low pumping current of 0.15A, it can be easily powered by standard adapters or battery packs, ensuring stable operation without overloading your circuit boards.

FAQ Section

Q. Can this pump run continuously for 24 hours?
A. While diaphragm pumps are durable, continuous 24/7 operation at maximum voltage may shorten the motor's lifespan. It is best suited for intermittent transfer and precision dosing applications.

Q. Is it compatible with microcontrollers like Arduino?
A. Yes! The integrated induction flow meter provides signal outputs that can be easily read by an Arduino or Raspberry Pi, making it perfect for smart DIY projects.

Q. What type of tubing should I use?
A. We recommend using flexible silicone tubing with an inner diameter of 5mm to 6mm to ensure a snug, leak-proof fit over the 6.4mm outer diameter ports.
