Ideal for projects requiring gentle flow and silent operation, it can be fully submerged, drawing water from shallow containers or sumps.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3–6V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlow Rate\u003c\/td\u003e\n\u003ctd\u003e80–120 L\/h (varies with voltage)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSubmersible Depth\u003c\/td\u003e\n\u003ctd\u003eUp to 0.5m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Length\u003c\/td\u003e\n\u003ctd\u003eApprox. 50cm (tinned leads)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e35mm x 30mm x 25mm (approx.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e~0.6W @ 3V, ~1.5W @ 6V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-automatic-plant-watering-system\"\u003eAutomatic plant watering system using a soil moisture sensor\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eDesktop water fountain or mini waterfall display\u003c\/li\u003e\n\u003cli\u003eAquarium water circulation or small sump system\u003c\/li\u003e\n\u003cli\u003eLiquid cooling loop for electronic components or small projects\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThe pump works with any 3–6V DC power source. It can be directly driven from a MOSFET or transistor with an Arduino, ESP8266, or Raspberry Pi. Ensure your microcontroller provides enough current via a driver circuit; a flyback diode is recommended to protect against voltage spikes.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect the red wire to positive (+) and black to negative (−). Use a 2N2222 transistor or L293D motor driver for speed control. Never run the pump dry for extended periods, as water acts as its lubricant and coolant.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
