Application Bulletin: Gorman-Rupp Trash Pumps & Industrial Wastewater Treatment Systems

Gorman-Rupp Ultra V Series

When discussing wastewater treatment systems, most are well-acquainted with their use in municipal settings. However, it’s important to recognize that various industries like chemical manufacturing, electric power, food processing, iron and steel manufacturing, automotive, and more. Many of these industries, during their production processes, generate undesirable byproducts that can find their way into the freshwater used within their operations. To discharge this wastewater safely back into surface water sources, it must undergo treatment to remove contaminants. Within wastewater treatment systems, the crucial role of transferring this wastewater for treatment falls to pumps. However, due to numerous solids and contaminants, traditional centrifugal and other positive displacement pumps can suffer damage, potentially causing disruptions to your entire system. In this application bulletin, we will explore the benefits of Gorman-Rupp’s self-priming trash pumps in industrial wastewater treatment systems to ensure the proper functioning of your treatment system and the reduction of pollutants.

How It Works

A lot of what makes a pump good for solids handling applications comes down to the impeller that is inside the pump. Many traditional centrifugal and positive displacement pumps have enclosed or open impellers. While these impeller are great for “clean” fluids like water. for solids-handling applications, they can cause build up in the pump causing problems like cavitation and inefficient pumping. However Gorman-Rupp trash pumps are equipped with a two-vane, semi-open impeller designed to handle up to 3″ by facilitating the passage of solids through the pumping making it the ideal solution for this application.

The Gorman-Rupp Solution

Gorman-Rupp Super T

This is precisely where Gorman-Rupp self-priming trash pumps emerge as the optimal solution for this specific application. Not only are these pumps are engineered to handle solids up to 3 inches in size while maintaining peak efficiency. They are equipped with self-priming capabilities, allowing you to install them at an elevated, dry location, with only the suction line submerged in the liquid. Once installed, they demand minimal maintenance, saving both downtime and money. Pumps like the Super T Series can maintain efficiency through the toughest solids or sludges where standard centrifugal pumps or positive displacement pumps would get damaged and could cause cavitation in your system.


We hope that this gave you a proper understanding of trash pumps, and how the function in a industrial wastewater treatment systems. If this seems like a solution needed for your operation, please contact one of our experts to help you find your ideal solution! We hope to see you again!
