Suction Lift Example
Specifics:Pond Size: 3000 GallonsPump Location: Above water level Filter: Biological Desired turn over is once an hour Plant pond and waterfall Koi Application #1Flow: 3000 gallons ÷ 1 hour = 3000 gph Head: (See Diagram Below) Friction head: Suction pipe: 3.0 feet Total Pipe Length 30.0 feet Locate the Plastic pipe schedule 40’ friction loss chart. The loss for 2 inch pipe with a flow of 3000 gph is 4.16 feet for every 100 feet of pipe or .0416 feet per foot of pipe. Total foot loss: 49.3 feet Total dynamic head TDH = Static head + friction losses + pressure head TDH = (9.0 dsch + 2.0suct) + 2.05 + 0 = 13.05 foot = 13 foot Refer to the Sequence 1000 performance chart. Locate the intersection of 3000 gph @ 13’ head. It falls between the 5000SEQ22 curve and the 4300SEQ20 curve. Select the 5000SEQ22 curve for proper results. Motor: 1/6 HP, TEFC, 1725 RPM
