Choosing an External Pond Pump

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 an External Pond Pump for your pond.

In order to maintain a healthy environment for your fish pond or water garden, you MUST run your water pump through your filter 24 hours a day, 7 days a week in season.

So it is important to pick the right External Pond Pump for your fish pond or water garden. Water pumps have variances in electrical usage and electrical costs.

The following formula will assist you in determining how much you will spend (approximately) per month to run the External Pond Pump you select.


  • Amps x Volts = Watts
  • Watts x 744 and divide by 1000 = KWH per month

We have also provided a useful Pump Cost Calculator to help you in planning for your pump.

External pond pumps refer to models of pond pump designed to sit completely out of the water. Because they sit outside the pond, external pumps, or in-line pumps, tend to require more time and effort to install but are more convenient and require less routine maintenance than submersible pumps.

Keep in mind that when purchasing an external pump, you may need to hide or camouflage the pump if you prefer a more natural looking pond or are concerned about equipment being visible.

Sequence Primer Series External Pond PumpAlso be sure to check whether or not your pump is self-priming, or able to draw water to itself. If you install an external pump that is not self-priming, you may need to take extra measures to ensure that your pump does not burn up in the event the power should go out and return.

Installing a check valve or placing the pump below the water level (digging a hole), can prevent the pump from running dry and eliminate some of the need for a self-priming pump. External pumps can be loud and could disturb your outdoor activities.
