Pump Products is now carrying the Goulds 4NS series submersible non-clog sewage pumps. These sewage pumps have a 4" 125# ANSI flanged discharge which allows the pump to pass wastewater containing up to 3" non abrasive waste solids. This pump can also be connected to a 4" wet pit guide rail or to a 4 x 6 guide rail connection. These 4NS series heavy duty pumps can reach high capacities and high heads and are specifically designed for a wide range of commercial and industrial level applications, such as in sewage systems, industrial dewatering systems, wastewater treatment plants, municipal lift stations and flood control. This is accomplished by pairing a ruggedly constructed pump with a powerful high performance motor. The pump itself is cast iron with two vane closed impeller with a a replaceable bronze wear ring. A dual mechanical seal with 305 series stainless steel metal components, BUNA-N elastomers and carbon/rotary vs. ceramic/stationary faces ensures leak free performance. The motor is CSA certified one-piece shaft made of 416 stainless steel. Each motor is air-filled and designed for continuous duty when fully submerged but can also operate up to 15 minutes in the air. All pumps listed below operate manually and include a 25 ft. power cord.
