Everything You Need to Know About Fountain Pumps
When choosing or replacing a fountain pump, understanding key terms is crucial. Here's a guide to help you make an informed decision.
Key Terms:
Head:
The "head" is the maximum height a pump can lift water. For instance, a 6-foot head means the pump can raise water up to 6 feet. However, at this height, the flow rate is minimal, nearing zero gallons per hour (GPH). If you require 200 GPH at 72 inches, you'll likely need a pump with a capacity of 300-600 GPH.GPH and GPM:
- GPH (Gallons Per Hour): Indicates how much water the pump can circulate per hour, typically measured at various heights.- GPM (Gallons Per Minute): Similar to GPH, but measures the flow per minute.
Pump Curve:
A pump curve shows how water flow changes with height. For example, a pump rated at 500 GPH might deliver 500 GPH at ground level but only 350 GPH at a 24-inch lift. Knowing your desired flow and height is essential when purchasing a pump.Determining Water Volume:
The water volume a pump can handle is influenced by its size and the tubing used. Tubing comes in two measurements: inside diameter (i.d.) and outside diameter (o.d.). If the tubing is too narrow, it will restrict flow significantly.
For example, using a 300 GPH pump with 1/2" tubing might only allow 253 GPH. Switching to a larger pump at 450 GPH with the same tubing can slightly increase this to 264 GPH. Always check the recommended tubing size for your pump and consider larger tubing if running it over long distances to minimize resistance.
Choosing the Right Pump:
Consider the desired effect?"whether you prefer a gentle trickle or a powerful stream.
- Waterfalls: A general rule is to provide 100 GPH for every inch of the waterfall's width at your pump's height. For instance, a 12-inch wide waterfall that is 3 feet tall would need a pump capable of 1200 GPH at 3 feet.
- Ponds: For small ponds, it's advisable to recirculate water once an hour. For a 500-gallon pond, aim for a pump with a 500 GPH capacity. Larger ponds may not require hourly circulation, as it can become costly.
Understanding these factors will help you select the right fountain pump for your needs, ensuring optimal performance and efficiency.
