Pond Pumps - External
Choosing the right water pump for your pond can make all of the difference in the world. Just because a pump may cost less to buy, it is not always the way to go.
The most important thing to remember is the electrical usage when looking for a water pump for your pond.
In order to maintain a healthy environment for your Koi pond or water garden, you MUST run your water pump through your filter 24 hours a day, 7 days a week.
So it is important to pick the right water pump for your Koi pond or water garden. Water pumps have variances in electrical usage and electrical costs.
The Benefits of External Pond Pumps.
First, external pond pumps can be far more energy efficient. However be careful not to include a typical swimming pool or spa pump into this category as pool and spa pumps can be huge energy hogs. As a general guide always check the amperage of the pump you are considering, anything drawing over 10 amps will also draw a significant amount of cash from your pocket every month in electrical costs.
The external pumps we are referencing are designed specifically for ponds and water gardens, and are engineered for energy efficiency.
For comparison purposes, a typical 4000 GPH (gallons per hour) submersible pond pump will typically draw between 10 amps all the way up to 15 amps, depending on the brand. In contrast, a comparably rated external pond pump will deliver 4000 GPH (gallons per hour) and only draws 2.3 amps. The resulting difference in energy consumption is 75% less than that of the submersible pond pumps.
When you start getting into larger ponds, 1000 gallons up to 20,000 and above – it’s usually a good idea to look into these more energy efficient pumps.
Other benefits of using an external pump include:
Easy to clean without getting your hands messy
Come with a removable leaf trap which clog less often
Easy to hook up to bottom drains or surface skimmers
Generally external pond pumps last longer, and are easier to repair
The following formula will assist you in determining how much you will spend (approximately) per month to run the pump you select.
Amps x Volts = Watts
Watts x 744 and divide by 1000 = KWH per month
KWH per month x Cost per KWH (located on your electric bill) = Cost per month
