Enter the general size of your pond. Measure the length, width, and average depth in feet. This helps calculate the total water volume.
Measure the width of your waterfall spillway in inches. We recommend 100 gallons per hour (GPH) per inch of waterfall width for optimal flow.
Enter the vertical elevation from the pond surface to the top of the waterfall, pipe length, and diameter. These factors affect pump performance and head loss.
The calculator determines pond volume, required waterfall flow, circulation needs, and accounts for head loss from elevation and pipe friction to recommend the proper pump size.
Enter the length and width of your stream bed in feet. For pondless waterfalls, we calculate stream volume using a standard depth factor.
Measure the width of your waterfall spillway in inches. We recommend 100 gallons per hour (GPH) per inch of waterfall width for optimal flow.
Enter the vertical elevation from the pond surface to the top of the waterfall, pipe length, and diameter. These factors affect pump performance and head loss.
For pondless waterfalls, the calculator determines stream volume, waterfall flow requirements, and accounts for head loss to recommend the appropriate pump size for your feature.
For Use in Pond Skimmers
If your pond has a skimmer, select a pump from this group. The skimmer protects the pump and increases its lifespan. These pumps are solids-handling and energy-efficient.
For Use Directly in the Pond
If your pond does not have a box-style skimmer, select a pump from this category. Note: These pumps are not for Pondless® waterfalls.
After using the pump calculator, you should now know how many gallons per hour (gph) you need to pump. Use this information to select a pump model from either the solids-handling pumps or energy-efficient pumps below.
Deciding between solids-handling and energy-efficient pond pumps depends on your priorities. Are you looking for lower maintenance or reduced energy costs?
Solids-handling pumps are ideal for ponds that frequently collect debris like leaves, twigs, or mulch. These pumps are designed to pass solid particles, up to two inches in size, through without clogging, making them a low-maintenance option.
On the other hand, energy-efficient pumps are built to minimize operating costs. They come with a cage that prevents solid debris from entering, though the cage will need periodic cleaning to avoid blockages.
If your pond is surrounded by trees and other vegetation, a solids-handling pump may be the best choice. But if energy savings are more important, an energy-efficient pump would be the way to go.
For Use in Pond Skimmers
Solids-handling pumps are extremely durable and lower maintenance because they are designed to handle small debris such as mulch, twigs, and small pebbles, that could enter your pump.
Available in three models with maximum flow rates of
2,000 – 9,000 gph
For Use in Pond Skimmers
Solids-handling pumps are extremely durable and lower maintenance because they are designed to handle small debris such as mulch, twigs, and small pebbles, that could enter your pump.
Available in three models with maximum flow rates of
3,000 – 10,000 gph
For Use in Pond Skimmers
Energy-efficient pumps are designed to perform optimally while reducing monthly operating costs.
Available in three models with maximum flow rates of
2,000 – 8,000 gph
For Use in Pond Skimmers
Energy-efficient pumps are designed to perform optimally while reducing monthly operating costs.
Available in three models with maximum flow rates of
2,000 – 5,000 gph
For Use Directly in the Pond
If your pond doesn’t have a skimmer to house a pump, then you want to choose an in-pond pump. These pumps include a pre-filter cage to prevent debris from clogging the motor.
Available in three models with maximum flow rates of
1,000 – 8,000 gph
For Use Directly in the Pond
If your pond doesn’t have a skimmer to house a pump, then you want to choose an in-pond pump. These pumps include a pre-filter cage to prevent debris from clogging the motor.
Available in three models with maximum flow rates of
600 – 2,000 gallons
For Use Directly in the Pond
If your pond doesn’t have a skimmer to house a pump, then you want to choose an in-pond pump. These pumps include a pre-filter cage to prevent debris from clogging the motor.
