Troubleshooting Guide for Goulds GT IRRI-GATOR™ Self-Priming Centrifugal Pumps

Dade Pump & Supply DBA De Ruiter Electric Motor Company specializes in the sale, repair and installation of Goulds Water Technology pumps and motors. Since our inception in 1960 we have partnered with Goulds to supply our customers with a consistently reliable and quality product. GT IRRI-GATOR™ Self-Priming Centrifugal Pumps are one of the most widely used irrigation pumps for a reason. 

A heavy-duty cast iron casing and self-priming capability equal a long lasting pump that is easy to use. Goulds upped the ante by designing a back pullout design allowing disassembly of pump for service without disturbing the piping.

Even with all of the above in your favor - issues will arise over time. Below are the common symptoms and possible causes. If you still have questions please don't hesitate to call or email us. If you are local to us in South Florida stop by our Miami repair shop and let our experts help you.
