When choosing a pond pump we usually look for an Asynchronous or Magnetic drive pond pump that is energy efficient and is designed to run 24/7. These pond pumps generally last the longest because there are no moving, touching parts. At times we will use direct drive pumps (less energy efficient – usually shorter life span) for applications that require high head height.
There are different styles and functions of pond pumps.
Skimmer Pump: A skimmer pump is a submersible pond pump that is placed within the skimmer to draw in the surface water and circulate it back up to the spillway.
Filter Pond Pump/ Solids Handling Pump: A solids handling pond pump can handle small debris and sludge and therefore is placed at the bottom of the pond. The pump feeds the debris and sludge into the pressurized filter and back up to the spillway or directly back into the pond.
SELECTING A POND PUMP FOR YOUR POND
Choosing the proper pump will provide you with:
•Pond Pump longevity • Pond Pump efficiency • Trouble free performance
Where will your pond pump be?
In pond at the bottom: look for a solids handling pond pump (great for pumping waste into filtration units)
In pond – In the skimmer: look for a skimmer/high volume pond pump (skimmer pond pumps do not need to handle solids as there is usually a filter basket or net prior to the pond pump.
HOW MUCH VOLUME DO YOU NEED?
LIGHT FLOW = 100 gph per inch of spillway
AVERAGE FLOW = 150 gph per inch of spillway
HIGH FLOW= 200 gph per inch of spillway
WIDTH OF SPILLWAY (inches) X DESIRED FLOW RATE (Light, Average, High Flow) = TOTAL GPH
* A pond should circulate approximately once every 30-60 minutes.
Therefore a pond that has 3600 gallons would need a pond pump or combination of pond pumps that have a gph of 3600-7200.
WINTERIZING YOUR PUMP
Turn off, clean and store all pumps indoors in a pail or container of water; this prevents the seals on the pond pump(s) from drying out. If your pond is 4’ or deeper the pumps can be left at the bottom of the pond.
