The 3 SQF-3 is a helical rotar pump which is not a high volume pump. It has a maximum of 2.2 gallons per minute but maintains a flow of 2 gallons per minute at 600ft to the water with only 440 watts required.

Example: 2 gpm at 600 feet to the water requires 440 watts.

We don't offer a module configuration that equals exactly 44o watts so you would need to look at the 425watt system and get just a little less water or look at the 510 watt system and get a little more water in a days time by increasing run time.

Reading the flow charts: Note the gallons per minute on the left side of the chart, find your water depth on the top of the curves.  Follow the curve down to where it intersects with your desired amount of flow line coming from the left.  Where the flow curve intersects with the volume line from the left come straight down to the required amount of watts to make the pump preform that volume. The watts are along the bottom of the chart. Don't follow the curve in the line coming down, you must come straight down from where the lines of flow and depth intersect. You will always want to round up to the next higher wattage system when the numbers for watts required don't match our systems.
