Long service life when conveying non-abrasive to slightly abrasive media

Due to their characteristics, the self-priming NOTOS® 2NS two screw pumps have a long service life and are preferably used in the oil & gas mid- / downstream, marine, power generation, process industry as well as in tank farms.

They convince through continuous conveying with low pulsation, which ensures gentle product handling. NOTOS® two screw pumps have one drive screw, transferring torque through a hydrodynamic film to the rotating intermeshing driven screw. Two spindle pumps are particularly suitable for non-abrasive to slightly abrasive, corrosive as well as non-corrosive and low to highly lubricating liquids. They have also proven themselves for low to high flow rates as well as pressures.

Capacities Range

• Flow up to 650 m³/h (2,860 gpm)
• Pressure up to 16 bar (230 psi)
• Temperature up to 300°C (570°F)
• Viscosity up to 100.000 cSt

Advantages

• Long service life
• Hydraulically balanced
• Wide range of applications
• Wide range of materials
• Optionally according to API 676 (American Petroleum Institute) requirements
• Low pulsation

To achieve maximum efficiency, the pump has been optimised using the High Efficiency Unique Design (HEUD) concept. This is characterised by extremely precise tolerances due to state-of-the-art technology as well as the optimised spindle profile. The wide range of materials, from grey cast iron and chrome-nickel steel to duplex, superduplex or hastelloy steel, ensures optimum pumping conditions in a wide variety of applications. Optionally, the pumps can be upgraded according to the standards of the American Petroleum Institute (API). These special requirements are mainly relevant in the oil & gas and petrochemical industries.
