NSL Centrifugal Pump

Vertical In-line Centrifugal Pump
Up to 3800 m³/h (16700 US gpm)

The NSL range of pumps represents high efficiency, low NPSH values, easy to installation and low maintenance. The NSL series is widely used within different applications and markets.

Design Features

The pump is an in-line, radially split, single-stage centrifugal pump with connecting flanges according to international standards.

The pump is designed for mounting with electric motors having different international flange dimensions.

The pump casing is equipped with a replaceable sealing ring. The impeller is made with double-curved blades to ensure low NPSH-values and high efficiency.

The bearing unit is equipped with sturdy ball bearings and the small types are fitted with lifetime-lubricated bearings. In the larger types the lower bearing is a double bearing for which a lubrication point is provided.

Within the marine industry the pumps are suitable as:

  • Fresh and seawater cooling pumps
  • Bilge and ballast pumps
  • Fire-fighting
  • General service pumps
  • Transport of slightly aggressive liquids with low viscosity such
    as diesel and lubricating oils.

Within industrial and utility applications the pumps are suitable for:

  • Industry water circulation
  • Cooling tower distribution
