Selecting the Right Pump for Your Water Fountain
Congratulations on picking your new water feature. The next step is to find the right pump whether it be an electric or solar pump. There are a ton of complex specs but selecting the right pump doesn't need to be a daunting process. At Fountainland we've simplified the process for you.
WATER PUMP IMPORTANT TERMS
Firstly, here are a few key terms you need to know:
Flow Rate (LPH)
The flow rate is simply the amount of water flow per unit time. It's usually based on litres per hour or LPH. Generally a larger fountain with a larger reservoir of water requires a more powerful pump.
Max Flow Rate (LPH)
The rate of flow of a pump is always highest at the lowest point and lowest at the highest point (max head). As water flows upwards the flow rate is continually decreased due to gravity up to the peak where the rate of flow is 0 LPH.
Max Head (m)
The max head is the maximum height the water can flow upwards to where rate of flow is 0 LPH. It's also known as "Lift".
HOW TO FIND THE RIGHT PUMP FOR YOUR FOUNTAIN
At Fountainland, we've simplified the process for you as follows:
STEP 1: Measure the distance between where the pump is placed to the fountain's peak water flow.
- For fountains with ponds, this is the distance from the pond to the peak.
- For fountains without a pond, this is the distance from the largest bowl to the peak.
- For wall fountains, this is the distance from the bowl to the mouth.
STEP 2: Look up the pump required in the below tables.
Example 1: Wall Fountain
Step1: For the wall fountain below, although the height is 67cm, we use the height from the bottom to the peak of the water flow, that is the lion's mouth, which is 40cm:
Step2: Based on the tables above, you may choose either of the following pumps:
- Resun King 1F
- Reefe RSF470
- Reefe RSFB800
Example 2: Fountain (self-contained)
Here we use the Catalina Concrete Fountain as the example.
Step 1: The Catalina is 185cm. We take a rough estimate of the distance from bowl to peak to be 70% of the full height. This gives us 0.7 x 185cm = 130cm.
Step 2: Look up the above tables, you may choose either of the following pumps:
- Resun King 2F
- Reefe RSF1360
- Reefe RSFB2500
Example 3: Fountain w/ Pond
When using a fountain with a pond, we recommend the fountain sit on a small pedestal of around 10-20cm. Note this may mean a more powerful pump.
Let's use the Catalina Concrete Water Feature example from before. If it were to be used with a pond and also sit on a slight pedestal of 20cm, the total distance from the pond to tip is 185cm + 20cm = 205cm.
The means the only pump suited in the above tables is the Resun King 4F.
It's important to select a pump that suits the fountain. We advise to not go overboard with too powerful of a pump as the water flow can be too much for the fountain to handle.
We have listed the recommended pump on the product pages. Do get in touch with one of our friendly Outdoor Decor Specialists if you have any questions or concerns via phone on 1300 657 511 or email at firstname.lastname@example.org.
