Description

Keep your water feature well-circulated using this Little Giant S900PT Stainless Steel Pump. This pump is designed to meet the demands of a variety of water features or ponds, and will work in hot water applications up to 110 degrees Fahrenheit. A bronze pump body and stainless steel chassis, combined with corrosion-proof fasteners, form a verstaile and durable pump which stands the test of time as it provides energy-efficient water circulation.

The unit is well suited for medium fountains, water gardens, ponds, and piped statuary, with its unique design lending exceeding versatility. The item is simple to sumberge in your skimmer, and sports a flow control valve next to the threaded discharge port to vary how much or how little water you wish the pump to move. An included, screened prefilter basket may be attached to the inlet for protection from excess debris, and this threaded element accommodates 3/4″ FNPT fittings if used inline. With a design that allows efficient and quiet operation, you can enjoy the benefits of this pump in the calm serenity of your own yard. Provide your pond or other water feature with healthy circulation using the S900PT Stainless Steel Pump. Two year limited warranty.

Note: Per the manufacturer, this product, Little Giant item number 517100003, is the replacement for Cal Pump item number S900T-20.

Pump Performance
Use this chart to determine the proper size pump for your pond. The height of the water outlet above the surface of the pond is called the Head Height. Gallons Per Hour (GPH) represents the maximum amount of water your pump is capable of pushing at a given Head Height. To ensure the pump’s best possible performance, reduce frictional losses by using the largest diameter hose possible.

Head Height (in feet)	Gallons per Hour

1′	795
5′	675
10′	470
15′	115

Pump Sizing

Continuous operation of these pumps in a pond or waterfall requires that the pump be sized for each specific installation. Pumps last longer and use less electricity when operated in the mid-range of their performance curve (see chart below). To calculate this, measure the height in feet from the surface of the pond water to the point where the water returns to the pond (perhaps a waterfall spillway). Add one (1) foot for every 90 degree elbow through which the water passes from the pump to the point of return. Add one (1) foot for every ten (10) foot length of tubing. This will provide the total height that the pump must move the water. Locate that height in feet on the vertical axis of the charts below and read to the right until you intersect the yellow/blue line. It is best to operate the pump in the head height shown by the blue area. If the lines intersect too far to the left of the graph you must choose a larger pump. If they intersect too far to the right you may either choose a smaller pump or install a ball valve at the discharge of the pump. By slightly closing the ball valve, never more than one third, you will create additional back-pressure on the pump that will allow it to operate correctly in the mid-range of its performance curve. Proper sizing of the pump to your specific installation will ensure optimal performance and maximum pump life.
