Submersible pumps are a popular choice for container water gardens, pond fountains and water features with small waterfalls.

Whether you have a preformed or a liner pond, a pond pump is important element in any water feature.

Stagnant water attracts mosquito infestations which, in addition to being a nuisance, are also undesirable due to the recent outbreaks of the West Nile virus. Therefore, it is of the utmost importance that you utilize a pond pump to circulates your body of water. A submersible pump has the capacity to power a small waterfall or a fountain jet several feet high. They are extremely quiet and unobtrusive.

For a smaller pond (up to 1000 gallons of water), a submersible pump is the most practical and economical solution. Submersible pond pumps can be placed directly in the pond and require relatively little installation. They are free of distracting noise, and for smaller ponds, can easily be used to drain your pond when necessary.

All that is required to set up a submersible pump is to place the pump at the bottom of the pool with the fountain jet at water level. It may be necessary to place the pump on bricks or rocks to get the right height. Lead the electric cord to the side of the pond and plug into a grounded outlet. Today, submersible pumps are magnet driven and no longer require the addition of oil coolants. Although more expensive initially they required less electricity and are more environmentally friendly. - There is no worry that the seal may crack and contaminates may enter the water.

Recommended....

It is recommended that you circulate your body of water at least once every 2 hours. Therefore you will need to size your pump to ensure that it has half the GPH rating as the volume of your pond in gallons. IE, if you have a 1000 gallon water feature, you will require at least a 500 GPH pump.

If you keep fish in your water garden, your water circulation demands will be drastically increased. Fish depend on the oxygen in the water to survive, therefore a proper pump for a fish pond must ensure that extra oxygen is both introduced into the pond, as well as distributed. The general rule of thumb is that you must double your pump GPH if you plan on raising fish.

What to look for in a good quality submersible pump:

  • Stainless steel shafts
  • Sealed plastic housings
  • Requires no oil
  • Energy efficient
