Vivosun 40W Submersible Water Pump (660GPH)

Standing water, sluggish circulation, and pumps that burn out from running dry are common problems in fish tanks, ponds, and hydroponic reservoirs. The Vivosun 40W Submersible Water Pump addresses all three: it moves up to 660 gallons of water per hour with a maximum lift height of 8.2 ft, draws water down to roughly 1cm above the tank floor through its bottom-inlet design, and shuts itself off automatically if the motor temperature exceeds 185°F (85°C), preventing damage from dry-running.

Pure copper wiring keeps power delivery stable and efficient, while a redesigned motor and pump body reduce operating noise and extend the unit's service life. The ceramic shaft rotor resists both acid and corrosion, so the pump performs equally well in fresh or salt water. A 360° filtering intake keeps debris out of the impeller, and the detachable outlet fits a range of hose and tubing sizes for use in aquariums, ponds, fountains, waterfalls, and various hydroponic systems.

Setup takes only a few minutes: place the pump flat on a stable surface, attach the rubber pads to reduce vibration and noise, connect the outlet to a compatible hose, and plug it in. The compact 5.5" × 3.7" × 4.9" footprint fits easily into tight spaces like DWC reservoir buckets, sumps, and small ponds, while the 5 ft power cord gives enough reach to keep the outlet outside cramped enclosures.
