NOTOS multi screw pump (2NS / 3NS / 4NS)

NETZSCH NOTOS multi screw pumps: positive displacement pumps with two spindles single-flow (2NS), three spindles single-flow (3NS) or two spindles double-flow (4NS) for low-pulsation conveying of thin to highly viscous media in oil and gas, petrochemical, marine and chemical applications such as tank farms and tank stripping. The NETZSCH brochure gives flow rates up to 2,500 m³/h (11,000 gpm), pressures up to 100 bar, viscosities up to 200,000 cSt and temperatures up to 300 °C; other NETZSCH publications quote lower limits (up to 1,500 m³/h, 80 bar), so the actual performance depends on series and size.
