Engineered for 24-hour continuous use, you can count on Flood Pumps around the clock. With high-quality SIC seals, Flood Pumps are built for a long and efficient life. Flood Pumps are built for submersible applications only, and because these pumps are designed for low head applications, they are compatible with 90% of all ponds. Flood pumps contain absolutely no oil and are completely fish safe. With built-in overload sensor shut-off protection, your pump protects itself against overheating and burning out. A Flood Pumps is the ideal pump for clean-outs and drainage because of its low suction point.

CHOOSING THE BEST PUMP FOR MY WATER FEATURE
When deciding which pump will work best for you pond, you will need to take three things into account: pond type, head height, and friction loss.
Water Garden, Few Small Goldfish: Circulate total pond water volume every 2 hours. Example: 2,000 GPH pump for 3000-gallon pond with 2" waterfall.
Fish Pond, Several Small Fish: Circulate total pond water volume every 1 hour. Example: 3,800 GPH pump for 3000-gallon pond with 2" waterfall.
Koi Pond, Several Large Fish: Circulate total pond water volume every 3/4 of an hour. Example: 5,500 GPH pump for 3000-gallon pond with 2" waterfall.
To calculate the head height, take the vertical height of your waterfall; the distance between where your pump is (typically in the skimmer) and where your waterfall is, and adding the static head pressure (pipe and fittings) 1′ for every 10" of tubing and 1′ for every elbow or "T" fitting.
Example: 3′ (vertical height) + 2.5 (25′ of tubing) + 2′ (for 2 elbows) = 7.5′ of Dynamic Head Pressure
Note: Head height is important to take into consideration due to the laws of fluid dynamics. Please refer to the flow chart above to help choose the correct pump.
CHOOSING THE RIGHT SIZE TUBING FOR MY WATER FEATURE
HOW MUCH WATER IS HELD BY MY WATER FEATURE?
Length x Width x Average Depth x 7.48 = Gallons
Example: A rectangular pond that is 15’ long, 10’ wide and 1.5’ deep is… 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
Length x Width x Average Depth x 0.8 x 7.48 = Gallons
Example: An oval pond that is 15′ long, 10′ wide, and 1.5′ deep is… 15′ x 10′ x 1.5′ x .08 x 7.48 = 1346 Gallons
Radius x Radius x Average Depth x 3.14 x 7.48 =Gallons
Example: A round pond that has a 12′ diameter and is 1.5′ deep is… 6′ x 6′ x 3.14 x 1.5′ x 7.48 = 1268 Gallons
Length x Width x 0.25 x 7.48 =Gallons
Example: A stream that is 20′ long, 3′ wide, and 3" deep is… 20′ x 3′ x 0.25 x 7.48 = 112 Gallons
