Pump with gear reducer NOTOS® 4NS

Thanks to the High Efficiency Unique Design (HEUD), the 4NS twin screw pumps ensure extremely continuous and gentle product conveying. State-of-the-art technology guarantees precise tolerances and an optimized screw profile, resulting in low life cycle costs and long service life. Geared twin screw pumps feature two shafts and four screws, with torque transmitted to the driven shaft via helical gears. This design is hydraulically balanced and prevents metal-to-metal contact between the screws, significantly reducing maintenance. The wide range of materials, from grey cast iron and chrome-nickel steel to duplex, superduplex, or hastelloy steel, allows for universal use in numerous industries. The 4NS application spectrum ranges from non-abrasive to moderately abrasive and from non-corrosive to corrosive pumped media. Additionally, both lubricating and non-lubricating fluids with low to high viscosities can be transported. Consequently, and due to their small footprint, they are used for pumping in shipping, power generation, tank farms, and the process industry. Furthermore, 4NS twin screw pumps meet the standards of the American Petroleum Institute (API) through an optional upgrade.
