Water Pump Advice for Water Blades and Waterfalls
Choosing the right water pump is essential to achieving a smooth, consistent flow across your water blade or waterfall. Whether you're creating a tranquil garden feature or a bold architectural cascade, the right pump ensures both performance and longevity of your installation.
Gravity Fed Water Blades – Simple, Elegant, Efficient
Gravity-fed water blades offer a beautiful, seamless curtain of water without the complexity of pressurised systems. Use the below table to help you choose the correct pump size and ensure even distribution across the blade’s width and a satisfying flow.
| Waterblade Width (mm) | Recommended Pump LPH |
| 200 | 2000 - 3000 |
| 300 | 3000 - 5000 |
| 400 | 4000 - 7000 |
| 500 | 5000 - 8000 |
| 600 | 6000 - 9000 |
Waterfall Pumps – Tailored to Your Design
Designing a complex waterfall feature? You’ll need to consider not just the width of the fall but also the vertical height (head) the water must travel.
How It Works
Our Waterfall Pump Calculator helps you determine the ideal pump size by factoring in:
- Width of the Water Feature (mm)
- Head Height (m) – the vertical distance the pump must lift water
Once entered, you'll receive a recommended pump flow rate in litres per hour (LPH), ensuring your waterfall maintains a powerful, even flow from top to bottom.
Why Pump Sizing Matters
Undersized pumps lead to weak or uneven water flow. Oversized pumps can cause splashing, waste energy, or even damage the feature over time. Our tools ensure you strike the right balance—efficient, powerful, and tailored to your design.
