The pump is self-priming
The Goulds GT20 IRRI-Gator pump is self-priming, meaning that once it has been initially primed and filled with water, it will reprime automatically when the water level rises above the end of the suction pipe. This self-priming design is a standard feature of the Goulds GT20 series pumps.
The pump's self-priming capability makes it suitable for a variety of applications, including lawn and irrigation systems, heat pumps, water transfer, air conditioning systems, and dewatering. It is designed to be field serviceable, with a back pull-out design that allows for easy servicing.
The Goulds GT20 pump has a corrosion-resistant impeller made of Noryl, a glass-filled, abrasion-resistant engineered composite material. While the impeller is designed to be durable, some users have reported issues with the plastic impeller breaking or separating into two parts. In such cases, replacement impellers made of silicon brass are available for purchase separately and are compatible with the Goulds GT20 model.
The self-priming feature of the Goulds GT20 pump simplifies its operation and maintenance, making it a popular choice for a variety of water-pumping applications. With its durable construction and corrosion-resistant materials, the pump is designed to provide long-lasting performance, even in demanding environments.

The pump has a corrosion-resistant, glass-filled Noryl impeller
The Goulds GT20 IRRI-Gator Self-Priming Centrifugal Pump is a powerful and reliable pump for a variety of applications, including irrigation, heat pumps, water transfer, and air conditioning systems. One of the key features that make this pump stand out is its corrosion-resistant, glass-filled Noryl impeller.
The impeller is a critical component of any centrifugal pump, and the Goulds GT20's impeller is designed to withstand corrosion and abrasion. By using glass-filled Noryl, a durable and corrosion-resistant composite material, the impeller is able to maintain its integrity and performance even when exposed to corrosive fluids or abrasive particles. This makes the pump suitable for a wide range of applications, including those that involve pumping corrosive liquids or liquids with solid particles.
The corrosion-resistant properties of the impeller are further enhanced by the pump's electro-coat paint process, which is applied both inside and out and then baked on for maximum protection against corrosion. This two-fold protection against corrosion ensures that the pump can withstand harsh environments and provides a long-lasting solution for a variety of pumping needs.
In addition to its corrosion resistance, the glass-filled Noryl impeller offers superior abrasion resistance. This feature is especially important in applications where the pump may come into contact with abrasive substances, such as dirt or sand. By reducing the wear and tear caused by abrasion, the impeller helps to extend the lifespan of the pump and maintain its efficiency over time.
While the Goulds GT20 pump offers many benefits, some users have expressed disappointment in discovering that the impeller is made of plastic. Despite this, the glass-filled Noryl material is designed to provide durability and corrosion resistance, making it a reliable choice for a wide range of applications. Overall, the Goulds GT20 IRRI-Gator Self-Priming Centrifugal Pump is a robust and versatile solution for various pumping needs, thanks in part to its corrosion-resistant, glass-filled Noryl impeller.
