Goulds Pumps GT20 IRRI-Gator 2HP Self-Priming Centrifugal Pump – Efficient Irrigation Solution

The Goulds Pumps GT20 IRRI-Gator is a state-of-the-art self-priming centrifugal pump designed for various applications, including lawn sprinkling, irrigation, air conditioning systems, heat pumps, water transfer, and dewatering. With a powerful 2 HP motor operating at 230 volts, this pump delivers reliable and efficient performance for both residential and commercial use.

Key Specifications

This pump is engineered to perform optimally, providing up to 86 gallons per minute (GPM) at a 5 ft suction lift with a discharge pressure of 20 PSI. The self-priming feature ensures that once the pump is initially primed and filled with water, it will automatically re-prime as long as the water level rises above the end of the suction pipe. This makes it an excellent choice for continuous operation.

Performance Ratings

The performance capabilities of the Goulds GT20 can be illustrated as follows:

• 20 PSI Discharge Pressure: 86 GPM at 5 ft suction lift, 70 GPM at 15 ft suction lift, 46 GPM at 25 ft suction lift.
• 30 PSI Discharge Pressure: 80 GPM at 5 ft suction lift, 67 GPM at 15 ft suction lift, 44 GPM at 25 ft suction lift.
• 40 PSI Discharge Pressure: 65 GPM at 5 ft suction lift, 57 GPM at 15 ft suction lift, 43 GPM at 25 ft suction lift.
• 55 PSI: 0 GPM at maximum of 127 ft dynamic head pressure.

Durability and Serviceability

The Goulds GT20 IRRI-Gator is built to last, with its cast iron construction ensuring strength and longevity. The back pull-out design allows for easy disassembly of the pump for service without disturbing the piping. The motor is designed with two compartments for easy access to wiring and replaceable components, enhancing the maintenance experience.

In addition, the pump features a bolt-down diffuser that provides positive alignment with the impeller. The diffuser is made from FDA compliant, injection molded, food-grade, glass-filled Lexan, ensuring durability and abrasion resistance in challenging conditions. The corrosion-resistant design, featuring an electro-coat paint process applied inside and out, further extends the lifespan of the pump.

Mechanical Seal and Performance

The Goulds GT20 also incorporates a mechanical seal designed with carbon/ceramic faces and BUNA elastomers. The use of 300 series stainless steel metal parts ensures that the seal remains functional and prevents running dry, which is crucial for maintaining the reliability of the pump.

In summary, the Goulds Pumps GT20 IRRI-Gator is an exceptional choice for anyone in need of a robust, efficient, and self-priming centrifugal pump. Its combination of power, performance, and durability makes it a standout option for lawn care, irrigation, and various water transfer applications.
