The Sunburst is Otterbine's signature pattern — a wide, gracefully tapered hemisphere that delivers excellent aeration while displaying a conservative yet striking silhouette.
The Sunburst produces a broad, symmetrical hemisphere of water — the classic, universally flattering fountain look, reaching 4–11 ft high and up to 40 ft across depending on horsepower, while circulating 530–1,100 GPM. It is aeration-forward — it moves more water than the display patterns.
Sunburst spray & pumping specifications (60 Hz)
| Horsepower | Spray Height | Spray Diameter | Pumping Rate |
|---|---|---|---|
| 1 HP | 4 ft | 15 ft | 530 GPM |
| 2 HP | 7 ft | 24 ft | 640 GPM |
| 3 HP | 10 ft | 30 ft | 775 GPM |
| 5 HP | 11 ft | 40 ft | 1,100 GPM |

Aeration & water quality
Every Otterbine aerating fountain is first and foremost an aerator. A patented mixed-flow design pulls oxygen-poor water from beneath the surface and moves it in high volume through the pattern, where it is oxygenated and returned — circulating the pond, breaking down thermal stratification, and supporting healthier water quality, clearer conditions, and fish habitat. Otterbine publishes independent, third-party oxygen-transfer and pumping-rate testing for its fountains.
How your fountain is built
An Otterbine aerating fountain is a configured system, assembled from four matched components so it arrives sized correctly for your pond and power:
- Motor unit & float — the oil-cooled submersible power unit and its one-piece float, chosen by horsepower and voltage.
- Sunburst pattern chamber — the interchangeable spray chamber that creates the Sunburst look. All 1–5 HP Otterbine patterns interchange on the same unit, so you can change the display later.
- Power Control Center (PCC) — the shore-mounted, ETL/UL508a control panel matched to the unit’s horsepower and voltage, with a GFCI/electrical-protection package.
- Underwater power cable — a factory-terminated submersible cable, sized to your shore-to-fountain distance. Select your cord length above to include the correctly-sized cable, or use our Cable Selector for a custom run.
Engineering & construction
- Motor: custom oil-cooled submersible, 3,450 RPM (60 Hz), 1.15 service factor (1.00 on 5 HP single-phase), dynamically balanced rotor.
- Materials: 316-grade stainless-steel motor housing and shaft, silicon-carbide mechanical seal, and an industrial thermoplastic pumping chamber and intake screen — engineered to run in effluent and brackish water.
- Float: seamless, one-piece high-density polyethylene filled with closed-cell polyurethane foam, with carry handles and integrated light pockets.
- Serviceability: upper-plate electrical quick-disconnect for straightforward service.
- Operating depth: runs in as little as 30 in (75 cm) of water.
- Certifications: ETL listed (60 Hz); UL508a control panels; CE (EU).
Complete your fountain
- Power cable — sized to your pond with our Cable Selector (correct gauge and length, to Otterbine’s 5% voltage-drop standard).
- Fountain Glo lighting — LED, Midi-RGBW and Maxi-RGBW color-changing light sets to run the display after dark.
- Options — sacrificial zinc anode kits (recommended for brackish/effluent water), intake screen kits, low-water level control, photocell and timer controls, wind control, and fixed-fountain stands for shallow water.
Warranty & support
Backed by Otterbine’s industry-first 5-year warranty and an exclusive pattern guarantee. Sold, configured, and supported by Natural Waterscapes — we help you match the horsepower, voltage, cable, and options to your specific pond.
Shipping
Ships by freight. Unit shipping weight approximately 150–160 lbs by horsepower; the control center and cable ship separately.
