Frequently asked questions

About the Maglev Vacuum Pump.

What overall efficiency does the NTV maglev vacuum pump achieve?

≥ 79 % overall efficiency, compared to 45 % for water-ring pumps, 52 % for Roots pumps, and 62 % for ordinary turbine pumps. The three-dimensional flow impeller and PMSM motor are the key contributors.

Does the maglev vacuum pump need sealing water or lubrication?

No. The maglev bearing is contact-free and the rotor assembly is oil-free. There is no sealing water requirement, eliminating water consumption and downstream effluent treatment.

What vacuum range does the NTV series cover?

The NTV series covers 10 – 70 kPa vacuum degree with flow from 20 to 1 220 m³/min, in 55 to 1 000 kW motor sizes.

Is remote monitoring included?

Yes. 24-hour intelligent monitoring is built into every NTV unit, including vibration, bearing gap, temperature and current diagnostics with remote diagnostics support.

Which industries typically use NordicLev vacuum pumps?

Chemical, pharmaceutical, papermaking, food and beverage, and high-purity processes where oil-free, contamination-free vacuum is critical.
