DESMI - Model NSL -Vertical In-line Centrifugal Pump
DESMI’s NSL pump is a further development of the well-known SL pumps which have been supplied for marine and industrial applications for more than thirty years.
The NSL range is a series of sturdy and reliable pumps, and the development of the pumps has been based on the latest methods for the calculation of strength and optimum performance. At the same time we have attached great importance to developing a pump type that meets the special marine and industrial market requirements for high efficiency, low NPSH values, easy installation/service, specific materials, and further an attractive price.
The NSL series is available in 25 different sizes up to 14" and is in accordance with the classification societies` requirements for marine pumps. DESMI has obtained type approval from several societies and all classification societies` certificates are supplied on request.
- 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.

All pump sizes are available as self-priming pumps either by adding a separate built-on priming pump of the water ring type, complete with suction strainer and water feed tank, or by using an air-operated ejector priming unit. The priming units can be manually or automatically controlled by means of a pressure switch.
