Centrifugal pumps

NSL

Vertical In-line NSL Centrifugal Pump
DN 65 to 400, Up to 3800 m3/h

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

Within 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.

DSL

The in-line DSL double suction centrifugal pump
DN 300 to 500, Up to 5400 m3/h

The DSL pumps are single-stage, double suction, vertical, centrifugal pumps. The design of the suction side provides for a perfect flow, and the inlet is placed in line with the outlet. Add to this the advanced double-suction impeller and the result is high efficiency and low NPSHvalues.The DSL series is widely used in different applications and markets.

Design Features
The pumps are fitted with bearings and mechanical shaft seal at both top and bottom. This gives a robust construction, designed for trouble-free continuous duty. The pumps are radially split. In spacer design, service including replacement of bearings and mechanical shaft seal can be carried out without removing motor and piping. Significant advantages to the benefit of the service personnel.

Within 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.

 

ESL

High-efficiency In-line centrifugal pumps
DN 25 to 100, Up to 200 m3/h

The ESL Centrifugal Pump is designed for high efficiency, low NPSH and is installation and service friendly. The ESL is widely used within different applications and markets.

Design Features

ESL pumps are single-stage centrifugal pumps equipped with mechanical shaft seal for maximum life and minimum friction loss. ESL pumps are single-stage centrifugal pumps with connecting flanges according to international standards. Further the pumps can be fitted with electric motors with flange dimensions also according to all international standards.

Modular S

Self-priming Centrifugal Pump
DN 32 to 125, Up to 650 m³/h

The Modular S Centrifugal Pump represents one of the most distinctive products of self-priming pumps. On the basis of 50 years of experience in the production of self-priming pumps we produce a pump series that meets the future demands for economical and reliable pumps. The Modular S is widely used within different applications and markets.

Design Features

Priming
The priming is based on the diffuser principle, which means that the priming ability is independent of valves and other mechanical elements as it is the flow of liquid that carries the air. In addition the diffuser principle has the effect that the Modular S can pump slightly polluted as well as air-mixed liquids.
