Notes
Bowls & small features (30–60cm wide)
Submerged on a small stand or flat stone
Bubbler / low spray head + reduced flow
Up to ~0.25–0.45m
Best for calm, splash-free patio displays
Small ponds (up to ~500 gallons)
Floating (recommended) or submerged on a platform
Single jet or fountain head + adjustable flow
Up to ~0.6–0.8m
Great balance of height and visual presence
Medium ponds (500–1000 gallons)
Floating (recommended) or submerged on a platform
Fountain head + adjustable flow
~0.4–0.7m
Best appearance without excessive overspray
Display height will vary depending on sunlight conditions, nozzle selection, and pump positioning.
Placement tip: For the best fountain effect, keep the pump as close to the surface as practical and minimise pumping height through tubing before the spray head. If you prefer a fixed position, place the pump on a stable platform (e.g., a flat stone or pump stand) and keep it fully submerged.
Want to run a cascade or connect to an existing feature? Use flexible tubing and keep the lift height as low as possible — see the performance tables further down the page for expected flow rates at different heights.

Note: Direct solar mode offers higher flow rates; battery backup ensures extended operation past sunset with slightly reduced height.
For cascades and fixed water features, the pump is best positioned below water level and connected using flexible tubing.
Versatile design for cascades, water features, and tubing setups with variable flow pump
Simple Setup & Seamless Operation
Easy Installation
Includes ground spike and wall mount for flexible solar panel positioning.
Adjustable Patterns
Switch quickly between two spray heads to create different effects.
Maintenance Tips
Keep your solar panel clean to maintain efficiency; rinse spray heads to prevent blockages.
Eco‑Friendly Innovation for Your Garden
Powered by the sun, the SE 500® brings beauty without mains electricity, reducing your carbon footprint while adding movement, sound, and style to your garden.
Optimised for spring and summer use. On bright winter days, it may operate if the panel is correctly angled towards the low sun and kept completely free from shade — expect occasional runs rather than daily operation.

Our display pump systems are designed for efficient, year-round operation, but perform best during spring and summer. Follow this guide for proper setup, seasonal adjustments, and maintenance to maximize performance and longevity.
The high-efficiency solar panel captures sunlight and converts it to clean power.
Energy is used directly during the day or stored in the LiFePO4 battery for later use.
The pump creates decorative fountain displays up to 80 cm high.
Stored battery power enables reliable operation in the evening.
Smart MPPT technology manages power for optimal performance in varying light.
