The NOTOS 3NS three screw pumps have a high-efficiency unique design (HEUD) that provides self-priming and a small footprint with continuous delivery and low pulsation to ensure minimal turbulence and gentle product handling.
The pumps have one drive screw, transferring torque through a hydrodynamic film to the two rotating intermeshing-driven screws. They can handle flows up to 1,760 gpm (400 cubic meters per hour); pressure up to 2,300 psi (160 bar); temperature up to 570°F (300°C); and viscosity from 1.5 to 15,000 centistokes (including LSD (Low Sulphur Diesel)).
Available in nitrated alloy steel or stainless steel and several port configurations, they also feature nitrated bearing bushes that help prevent start-up failures and support radial loads. Under suction pressure, the pumps require only one mechanical seal. They are offered with an optional magnetic drive. Additionally, they are available with an optional upgrade that meets military standards including shock tests.
The pumps are for use in engine lubrication and fuel oil applications, including lubrication oil pumps for engine rooms, lubrication oil transfer for diesel engines, and transfer pumps for fuel oil and diesel.
