Meet the Beckett 7218110 430 GPH 31 watt low-water shut-off fountain pump—a dependable, energy-efficient solution for your indoor and outdoor water features. Designed to power fountains, ponds, aquariums, statuary, hydroponics, and aquaponics, this submersible pump integrates seamlessly into a variety of setups. It’s part of the Beckett M400AS family, delivering reliable performance when you need precise water movement without constant tinkering.

Protection you can trust: a built-in low-water sensor automatically stops the pump if water levels drop too far, preventing burnout and extending the life of the unit. When water returns to a safe level, the pump restarts automatically, so you don’t have to monitor it constantly—keeping your fountain or system running smoothly.

Power and flow that adapt to your scene: with a maximum lift of 8.2 feet and up to 430 gallons per hour, this pump delivers strong, consistent flow for larger waterfalls or dramatic spray effects. At just 1 foot of lift, it sustains around 400 GPH, providing ample circulation for ponds and tanks of moderate size. The flow is adjustable via an integrated valve, letting you tailor the stream height and intensity to your aesthetic and ecological needs.

Key compatibility kicks in with a 1/2 inch ID tubing connection and a generous 16-foot power cord, giving you flexibility in placing the pump and routing lines without forcing a cramped setup. It runs on standard 120V power and draws only 31 watts, balancing performance with energy efficiency for everyday use.

Ideal applications include:

• 5 to 7-foot fountains where a bold, reliable stream is desired
• Indoor and outdoor ponds and water features
• Aquariums, fish tanks, and statuary fountains
• Hydroponics and aquaponics systems that require steady water movement

What makes this pump stand out is the combination of protective low-water shut-off, automatic restart, and precise flow control in a compact, submersible package. It minimizes downtime, reduces risk of damage from dry-running, and adapts to a variety of installation scenarios—so you can focus on enjoying your water feature, not managing it.

Practical tips for optimal performance: place the intake away from debris and ensure the return line delivers water back to the source to avoid splash-back losses. Use a pre-filter to extend the life of the impeller and keep water clean, and verify tubing connections are fully seated to prevent leaks. If you notice a drop in flow, check for air pockets or blockages and adjust the flow valve gradually to achieve the desired effect.
