GOULDS 4NS 4″ Non-Clog Submersible Sewage Pump

The Goulds Water Technology 4NS 4” Non-Clog Commercial Submersible Sewage Pumps feature a cast iron, two vane closed design impeller for high efficiency and maximum wear life; an optional bronze impeller is available. The pump has a replaceable bronze wear ring to renew running clearances and efficiencies to original conditions. The 4NS has dual mechanical seals, and a heavy duty cast iron, volute type casing for maximum efficiency. Motor is rated continuous duty for submerged condition in water that is 40º C or below.

The 4NS is a heavy duty design for a range of commercial and industrial applications including sewage systems, flood and pollution control, industrial dewatering, waste water treatment plants, municipal and subdivision lift stations.
