| Type of Use |
Approx. Pond / Feature Volume |
Typical Setup |
| General Circulation / Oxygenation |
6 000 – 14 000 litres
(≈ 1 300 – 3 100 gallons) |
Large garden or koi ponds; adjust speed (50–100 %) for strong, efficient water movement |
| Filtration / Water Cleaning |
Up to 12 000 litres
(≈ 2 640 gallons) |
Powers medium‑to‑large filtration systems or pressurised filters; run at higher speeds for full turnover |
| Waterfalls / Streams / Fountains |
Effective up to 5–6 m lift |
Produces a smooth, adjustable flow—ideal for medium to tall waterfalls and decorative displays |
| Smaller Ponds (< 3 000 litres) |
Suitable only at low speed (30–40 %) |
Lower flow settings maintain gentle circulation without excess turbulence |
Tip: To estimate pond volume (L), multiply average length (m) × width (m) × depth (m) × 1 000.
For example, 3 m × 2 m × 0.8 m ≈ 4 800 L.

What Does Head Height Mean?
Head Height is simply how high your pump can push water – and the higher it goes, the less flow you get. Check the table to see exactly how the Vari‑Flow Pro 12000 performs at different lift heights when running at full power, so you can match the right setting to your pond or water feature.
The table below shows the approximate flow rates you can expect at common head heights when operating at maximum output (100%). If you use a lower speed on the controller, the flow rates will reduce proportionally, helping you save energy and tailor performance to the season.
