Mini Silent DC5V Self-priming Diaphragm Pump

Dimensions: 2.1 × 3.9 × 1.2 cm (0.82 × 1.53 × 0.47 inches); weight: 14 g. Constructed with ABS plastic housing for safety and corrosion resistance. Operates at DC 5.0 V with current draw under 100 mA and power consumption of 0.3 W. Delivers a flow rate of 40–90 ml/min and maximum working pressure exceeding 20 kPa. Features 3.5 mm inlet and outlet diameters, smooth wired interface for stable output and reliable power-on performance. Engineered with a finished motor to minimise heat generation and ensure ultra-low noise operation. Designed for compact integration in space-constrained applications including robotic vacuum cleaner components, household appliances, water dispensers, shower systems, and air-conditioning drainage solutions. Its self-priming capability enables reliable start-up without manual priming, while the diaphragm mechanism ensures leak-free, oil-free pumping ideal for clean environments. Suitable for low-pressure, low-flow precision fluid handling tasks where quietness, light weight, and consistent DC operation are critical — especially in consumer electronics and smart home devices requiring long-term intermittent or continuous duty cycles.
