Non Pressuries Non-Clog Submersible Pump “NSEW” Series

Non Pressuries Non-Clog Submersible Pump “NSEW” Series

The “HET” presents its unique “NSEW” Series, a Single Stage Submersible Slurry Application Pump. This remarkable pump is equipped with an Agitator and Aerator System, transforming it into a Non-Clog Slurry Pump capable of handling hefty slurry solids up to 40 mm in size, with a capacity to manage heavy slurry up to 2.0 kg/m3.

With a double mechanical seal and one non-pressurized seal, it adeptly handles heavy slurry with a density of up to 2.0 kg/m3, ideal for abrasive, corrosive heavy sludge in diverse industries, including industrial waste removal. The non-pressurized mechanical seal assembly reduces hydraulic pressure on rotating parts, enhancing durability. The single-volute pump casing ensures efficiency, while an inducer, temperature sensors, and a cooling jacket add versatility. In demanding environments, choose the “HET” Submersible Slurry/Sewage Pump for optimal performance and unwavering reliability.
