The R385 DC Water Diaphragm Pump 12V is a compact, self-priming fluid transfer pump designed for microfluidic control, automated plant watering systems, aquarium fluid circulation, and DIY… 6V to 12V DC (9V-12V nominal) · 0.5A - 0.7A load current (1.5A - 2A peak startup current).
The R385 DC Water Diaphragm Pump 12V is a compact, self-priming fluid transfer pump designed for microfluidic control, automated plant watering systems, aquarium fluid circulation, and DIY electronics prototypes. Built around an internal DC motor driving a mechanical diaphragm mechanism, it creates a vacuum to lift and push non-viscous clean liquids without requiring priming.
Unlike submersible pumps, the R385 is non-submersible and operates externally. It comes equipped with flexible silicone dampening ring mounts that suppress mechanical motor vibration and noise during operation. It features two 8.5mm outer diameter barbed nozzle ports that fit standard 6mm inner diameter flexible silicone tubing.
Operating smoothly across a voltage supply of 6V to 12V DC (9V-12V nominal, 1A-2A recommended startup power supply), it delivers a maximum flow rate of 1.5 to 2 L/min. It interfaces effortlessly with standard relay modules, MOSFET drivers, or motor controllers like the L298N for micro-controller-driven automation via Arduino, ESP8266, or Raspberry Pi.
