Meet the MOUNTAIN_ARK DC 12V Submersible Clear Water Pump

Compact, reliable, and built for immersion, this pump brings steady water movement to small aquariums, decorative fountains, and compact hydro setups. Its submersible design lets you place it exactly where you need it, delivering consistent flow with minimal fuss.

Five levels of adjustable power for flexible setups

Fine‑tune water motion with five power settings. The pump supports a range of flow rates to match your tank or fountain design:

• 800 L/H (210 GPH)
• 680 L/H (180 GPH)
• 560 L/H (150 GPH)
• 440 L/H (115 GPH)
• 320 L/H (84 GPH)

Such versatility makes it possible to balance circulation, aeration, and decorative spray patterns across different layouts.

Impressive lift, compact footprint

With a maximum lift height of 14'9" (450 cm), this pump can push water through tubing to elevated nozzles or features, expanding your design options without a bulky pump.

The unit runs on 12 V DC and uses a 5.5 x 2.1 mm connector (adapter not included), keeping setup simple with common power supplies.

Durable, easy to maintain

Two brass nozzles are included and are detachable for quick cleaning. The design supports tool-free removal, so you can swap nozzles or clear debris without interrupting your setup.

• Brass nozzles for durability and consistent spray
• Detachable and cleanable components for easy maintenance
• Non-self-priming and must be fully immersed during operation

Specs, fit, and practical tips

The pump operates within 0–60°C (32–140°F), making it suitable for most freshwater environments. The inlet/outlet diameter is 20.5 mm, which helps when selecting compatible tubing and fittings.

In practice, it’s a practical choice for refreshing a small aquarium, creating a tabletop fountain, or circulating water in compact terrariums or hydroponic setups. The combination of adjustable flow, durable build, and submerged operation offers flexibility without heavy equipment or complicated wiring.

Note: Adapter not included. The pump must be fully submerged to operate correctly, and the two brass nozzles enable quick changes to the water display.
