When you’re planning to build a pond one of the first things that you need to think about is the pond water pump.
The decision will depend on the size of the pond, flow rate required and efficiency of the water pump.
Tip 1: The minimum flow rate should be 1/2 of your pond volume. Sometimes even this is not enough.
Tip 2: If you have a waterfall in your pond, you’ll need to increase the size of your pump.
Which type of pond water pump is best?
This depends on the design, size and purpose of your pond.
- How long the pump will last
- How often it needs to be cleaned
- How clean or dirty is the water where the pump will be working
The Best Pond Pump
1. External Pond Pump
Here are the 4 reasons to choose an external pump
external pumps tend to be more energy efficient
they last a lot longer than submersibles
they cost less to operate over a long period of time
the parts are cheaper to buy than submerged pumps.
For these reasons when choosing a product it’s advised to go with an external pond pump, if possible.
You might find that decision saves you a lot of time and money.
2. Submersible Pumps

Be aware that if your buying a cheap submersible pump, they tend to have a shorter life than external pumps. Most of them will last for a little over 1 year because they’re sitting in the middle of the pond and absorbing dirt and pond filth all of the time. This eventually causes wear on the pond pump and causes it to have a shorter life than an external pond pump.
