The performance of a Goulds GT15 pump, specifically its capacity to move fluid, is determined by its output. This parameter is typically quantified as flow rate, measured in gallons per minute (GPM), and total dynamic head (TDH), measured in feet. The specific flow rate and TDH a particular GT15 pump achieves are dependent on the impeller size, motor horsepower, and the specific conditions of the application, such as fluid viscosity and piping configuration. For instance, a GT15 with a larger impeller and higher horsepower motor will generally produce a higher flow rate and TDH compared to a model with a smaller impeller and lower horsepower.
Understanding the performance characteristics of this type of pump is essential for selecting the appropriate model for a given application. An accurately sized pump ensures efficient operation, preventing energy waste and premature failure. Proper sizing also contributes to the overall system’s reliability and longevity. Historically, the Goulds GT series has been recognized for its robust construction and reliable performance in various residential and light commercial applications.
