What does a Pond Pump Do?
A pond pump is connected to the electrical supply and submerged at the
bottom of the pond. It provides all the power to circulate the water
through waterfalls, fountains, ornaments, filter systems, and
The proper pump and circulation system is very important for the ecosystem of your pond. Pumps that power water features and filters keep the water moving, providing the necessary oxygen levels for healthy fish and plants and discouraging mosquito populations.
A good rule of thumb for evaluating how large pond pumps should be to provide
filtering only is to choose a pump that will turn half the volume of the
pond per hour. Therefore, if you have a pond whose volume is 1000
gallons, a pump that will pump 500 gallons per hour is adequate.
Generally, the more features added to the system, the
more powerful the pond pumps must be.
If you want to use a pond skimmer, the best way to evaluate the
size of the pond pumps are to multiply the surface area of the pond by
10 to 15 times and use a pond pump with that many gallons per hour
Waterfalls present their own challenges. You must keep in mind how
wide the water fall is and how high. Be sure to check the "head" or pumping
height rating on any pond pump you are considering. A waterfall with a 10 foot head
will need a pond pump capable of delivering that type of pressure.
Pond Pumps deliver much less
than their maximum rating at higher pumping heads, and longer pipe
lengths or 90 degree elbows will increase the head measurement.
After you have decided how much volume you need to turn for filtering
how much surface area you need to skim if you are going to use a skimmer, and
how much head height you need for the waterfall(s), read the
specifications on each pond pump. Choose the pond pump which delivers at
least the minimum requirements for the most heavy activity.
Most pond owners choose a slightly more powerful pond pump, as it
is less expensive to invest in a single pond pump and, contrary to
popular opinion, higher pumping capacity will not diminish the
biological activity of the filter.
In some cases, it may be advisable to use multiple pond pumps
for multiple or larger streams, fountains, or heavy fish loads.
