The Goulds 3SD and 4SD sewage pumps are high capacity submersible sewage pumps designed specifically to handle commercial and industrial level wastewater applications. All of these pumps have maximum capacities in the three digits and have the construction to handle those numbers. Typical application settings include hospitals, trailer courts, farms and motels. Goulds 3SD and 4SD pumps are often prominently featured in flood and pollution control applications. Both series can also be used for general sewage system, dewatering and effluent applications as well. Pumps in both series include a dual seal (outer: silicon carbide vs. silicon carbide; inner: ceramic vs. carbon) for extra protection and a seal sensor probe that can detect if anything penetrates the seal. That's unlikely because each pump contains a cast iron, two vane, semi-open, nonclog impeller with pump out vanes to ward off any impediments. The rest of the pump is similarly constructed with a rugged cast iron volute and 300 series stainless shaft and fasteners. These pumps are capable of running dry without damage to the components. The main difference between the two series is in the solids handling ability and subsequently, the discharge size. 3SD pumps can pass 2.5" waste solids through the 3" NPT horizontal discharge while 4SD pumps can pass 3" solids through a 4" NPT horizontal discharge. Some 4SD pumps have 7 HP motors as well. All models listed here are manually operated and include a 20 ft. power cord.
