Centrifugal pump NSL

for seawaterfor fresh waterwith electric motor

Vertical In-line Centrifugal Pump Up to 1800 m³/h (7900 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. Applications 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 • Diesel transfer • District heating • District cooling The DESMI NSL pump meets the special marine and industrial market requirements for: • High efficiency • Low NPSH values • Easy installation/service • Specific materials • Compact design • Standardized to modular design • Outstanding hydraulic design performance • Spacer-coupling options for easy maintenance • Robust shaft design • High efficiency impeller with low NPSH values • Self-priming ability with a separate built-on priming pump Technical Product Specifications The design of the NSL pumps is for medium/high flow capacities up to 1800 m³/h (to 7,900 US GPM) & medium head up to 220mLC. The pump can be configured as vertical and be of the radially split, single stage centrifugal pump type with connecting flanges according to international standards or as horizontal in-line and radially split, single stage centrifugal pump with connecting flanges according to international standards acc. to DIN, ANSI or JIS.
