||Thermoplastic exterior is corrosion-proof
||Efficient, reliable and low-cost operation
||High volume pumps, great for central filtration systems
These self-priming pumps all feature compact efficiency, reliability, and low cost for central filtration systems and large ponds. The pump's housing body boasts an injection-molded, corrosion-proof thermoplastic exterior with high-temp Noryl. The extra large strainer pot has a comfort grip lid for quick access to the strainer basket. Each motor includes a stainless steel shaft. The seal plate with integral diffuser and enclosed glass-filled thermoplastic impeller provide superior strength, corrosion resistance, and excellent performance. UL- and CSA-listed. One-year manufacturer warranty. Note: Self-priming pumps need to be hard-wired and do not include power cord.
The chart above shows the relationship between head height (the height difference between the pump and the final height that the water is lifted) and Gallons Per Hour (GPH). To determine which pump model is recommended for your waterfall or fountain, find your desired head height in the left column and follow that gridline right to your desired GPH along the bottom. The curved line to the right of that intersection represents the recommended pump model.
The flow chart represents the water pump operating under ideal conditions, using the recommended sized tubing with no bends or elbows and operating in a free-flow manner. Situations that will reduce the output of a water pump below the above ratings include: using tubing with a smaller diameter than recommended, any bends or elbows in the return line, and placing any restrictions on the output side of the pump. These restrictions may be in the form of a filter and ball valves used to control the flow rate.
It is difficult to determine the effects that restrictions may have on the output of a water pump. Choose a model of pump that offers a higher output than previously anticipated. By doing so and installing a ball valve on the outlet side of the pump, you will be able to not only control the water flow, but will also be assured that you will have sufficient water flow once the unit is installed.
