WHAT PUMP SHOULD I GET?
The pump is the heart of your pond. It circulates the life blood of the pond which is the water.
In order for the pump to do its job properly, it needs to be sized correctly. Your pump should be able to circulate the entire gallons of your pond every two hours. You must first determine the amount of gallons in your pond. You can achieve this by measuring the length then multiplying it by the width, then multiplying it by the depth and finally multiplying the total cubic feet by 7.5 gallons per cubic feet. Example: (A 10 ft. square pond) multiply 10 ft. long x 10 ft. wide x 5 ft. deep = 500 cubic feet. Then multiply 500 cubic feet by 7.5 = approximately 3750 gallons. Round down slightly because your pond is not filled to the top. We recognize that most ponds are not square or rectangular. If you furnish us with the shape of your pond and its depth, we will assist you in determining the number of gallons in your pond.
The next step is to determine what the total dynamic head pressure is. The total dynamic head pressure encompasses the vertical height the pump must overcome “ A ” which includes your waterfall. This is determined by measuring from the top of the water (not from the bottom of your pond) to the top of the falls. Figure “ B ” the distance of the piping in feet that the pump is pushing the water through. You will need to physically measure this length. Next, count “ C ” all the fittings (such as the number of elbows and reducers). Finally, “ D ”, count the number of miscellaneous items such as ball valves and bulkhead fittings. Now, use the following formula: A + (B / 10) + (C / 2) + (D / 4) = Approximate Head Pressure.
With the formula above, you can determine the approximate head pressure. Additional factors will be the width of the sheet of water you wish to have for your waterfall. It is a good rule of thumb to use 125 gpm for every inch of the width of the water sheet. Example: (Spillway is 15” wide) multiply 125 x 15 = 1875 gph. The formula for the sheeting of the water and the pump flow rate per hour does not always match. The examples we have shown indicates that the circulation requirements (3750 gallons divided by 2 = 1875) and the sheeting gallons (125 x 15” = 1875) are the same. If more sheeting is desired, you need to determine your pumping gallons per hour for the waterfall not the pond water circulation. For example, if you want 24” of sheeting, multiply 125 x 24” = 3000 gph. This means you will have to get a pump that gives you 3000 gph instead of 1875 gph. This also allows you to have more circulation of the entire pond.
These formulas are the most user friendly that we have found to act as a guideline to help you estimate the pump head you will require. You should always select the pump for the maximum outflow you expect. The flow can always be reduced by adjusting the discharge valve. We strongly suggest that you have us review your estimate and confirm or adjust your findings or just give us the information on your pond and let us come up with the proper pump requirement. It is always recommended to have a spare pump on hand to hook up immediately should the one that is operating 24 hours a day, 7 days a week go down.
