12V Diaphragm Water Pump – 3L/min

The 12V DC Diaphragm Water Pump is a compact fluid transfer solution designed for controlled water flow in embedded systems and small-scale applications. It operates at 12V DC with a flow rate of up to 3 L/min and features a self-priming diaphragm mechanism for efficient suction and discharge. The pump ensures stable performance with moderate pressure output and reliable lifting capability up to 2.5 meters. Its sealed design supports consistent operation in intermittent duty cycles. Suitable for water circulation, irrigation systems, and fluid handling in engineering projects.
