Vivosun 220W Submersible Water Pump (4500GPH)
Bigger ponds and taller waterfalls need more than a mid-size pump can deliver. Once the head height climbs, flow slows to a trickle. The Vivosun 220W Submersible Water Pump (model PG4500-S) is sized for these larger features. It pushes up to 4,500 GPH, still moves 1,783 GPH at 9.8 ft of head, and reaches a maximum lift of 19 ft. It runs at a quiet 30–40 dB.
The pump's 1-1/2″ inlet and outlet accept 1-1/4″ or 1-1/2″ ID tubing, which keeps friction loss low on long runs to a waterfall or filter. Inside, a wet rotor/wet bearing motor runs cool, and a silicon carbide ceramic shaft and drive ring resist wear. The IPX8-rated housing handles continuous submersion. A removable pre-filter screen keeps large debris away from the impeller, and five outlet positions from 0° to 180° let you aim the discharge to match your plumbing.
The Vivosun 220W Submersible Water Pump fits ponds up to roughly 720 gallons. It can run submerged or inline in dry installations to power fountains, streams, filtration systems, large hydroponic reservoirs, and irrigation lines. A 20.3 ft (6.2 m) cord and built-in carry handle simplify placement. The pump is designed for fresh water only.
