Goulds GT15 IRRI-Gator Self-Priming Pump: Reliable Water Movement for Homes and Small Sites

The Goulds GT15 IRRI-Gator is a compact, dependable centrifugal pump designed to handle irrigation, transfer, and environmental cooling tasks with minimal fuss. Its self-priming capability helps you start quickly, and it resumes operation as water returns to the suction line, reducing manual priming and downtime in fluctuating water levels.

Built for practical, everyday use, this pump emphasizes serviceability and durability. The back-pullout design lets you disassemble the pump for maintenance without disturbing piping, while a two-compartment motor provides easy access to wiring and replaceable components. The diffuser bolts down to ensure precise alignment with the impeller, and a stainless wear ring in the diffuser supports longer performance in abrasive conditions.

Materials and construction are chosen to withstand real-world conditions. The casing uses cast iron for strength, and wetted parts include FDA-compliant alloys and glass-filled polymers for durability and abrasion resistance. The design also prioritizes safety and reliability with a corrosion-resistant finish and a built-in overload protection that supports continuous operation when needed.

Whether you’re setting up a garden irrigation system, cooling a small HVAC loop, or transferring water between tanks, the GT15 offers a balance of capability and convenience. It’s compatible with standard 1½" NPT suction and discharge piping, and it delivers solid performance across a range of applications without demanding complex maintenance.
