Manufacturing & Commissioning of 4FG Double Suction Pumps for the Wastewater Treatment Industry

4FG Double Suction Pump

Working in partnership with a municipal wastewater treatment client, Smart Turner Pumps Inc designed and manufactured two the above double suction pumps for use in a pressure screen wash application. Using our in house milling, boring, and turning capabilities, the bodies of the pumps were built to our customer's specifications. Upon quality controlled construction and assembly, hydrostatic testing, and final engineering approval, direct delivery to the end user and on-site commissioning was coordinated.

In addition to the units as finished products, Smart Turner Pumps provided training to local wastewater personnel on the operation and maintenance of such to further explain and note their features, including discharges, gauges, bearings, and motors. With consistent performance in pumping water to, and through, municipal pumping stations, our follow up customer relations have indicated their high degree of satisfaction with our exemplary production and assistive cooperation throughout the course of this project.
