Adjustable Submersible 12V Water Pump

This compact submersible water pump operates on DC 5.5–12V input and consumes 3W of power. It delivers a maximum flow rate of 200L/H (44GPH) with a maximum lift height of approximately 1.5 metres. The outlet diameter is 8mm, and the unit weighs light for easy placement. Constructed from durable hard plastic, it is fully submersible in both freshwater and saltwater environments. The 46-inch power cord provides flexible positioning. Two integrated suction cups secure the pump firmly to smooth surfaces underwater, requiring no additional mounting hardware or tools. The pump features a front-facing rotary knob for precise, tool-free flow adjustment — ideal for tailoring water movement to your aquarium’s bioload, fountain’s visual effect, or pond’s oxygenation needs. Its quiet operation and low energy draw make it suitable for continuous 24/7 use in home aquariums, desktop fountains, or small garden ponds. Designed for simplicity and reliability, this pump supports natural water circulation and surface agitation to enhance gas exchange — helping maintain stable dissolved oxygen levels and mimicking gentle river or coastal currents.
