The Goulds Pumps GT15 IRRI-Gator is a self-priming, single-phase centrifugal pump rated at 1.5 hp. Once it is initially primed and filled with water, it reprimes when the water level rises above the end of the suction pipe. It is designed for lawn sprinkling, irrigation, air conditioning systems, heat pumps, water transfer and dewatering.
The casing is cast iron with a four-bolt, back pull-out design, so the pump can be taken apart for service without disturbing the piping. The casing has tapped openings for a vacuum gauge and a casing drain. The diffuser is bolt-down for positive alignment with the impeller and has a stainless wear ring for extended performance in abrasive conditions. The diffuser is made of FDA-compliant, injection-molded, food-grade, glass-filled Lexan. The impeller is FDA-compliant, glass-filled Noryl that resists corrosion and abrasion.
The two-compartment motor gives easy access to the wiring and replaceable components. An electro-coat paint is applied inside and out, then baked on, for corrosion resistance. The pump's ratings are within the motor manufacturer's recommended working limits, so it can run continuously. The pump design prevents the mechanical seal from running dry. Pumps are tested by the manufacturer and may contain some water from that testing.
