Vertical In-line Centrifugal Pump

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
  • Diesel transfer
  • District heating
  • District cooling

Self-priming Centrifugal Pump

Up to 400 m3/h (1760 US gpm)

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.

Submerged lubrication oil pump

Up to 400 m3/h (1760 US gpm)

The DESLUBE series is a submerged deep well pump designed for Main Engine Lubrication oil supply for especially large two-stroke engines. The design is based on our long time experience of manufacturing deep-well pumps as well as the design features from our in-line centrifugal series. The pump is placed in the tank sump supported by dome flange and requires no further suspension. The sturdy construction ensures a reliable operation with low noice and vibrations level.

  • Low NPSH
  • Low noice or vibrations
  • Low maintenance costs
  • High reliability
  • High flexibility

The in-line DSL double suction centrifugal pump

Up to 400 m3/h (1760 US gpm)

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 within different applications and markets.

High-efficiency In-line centrifugal pumps

Up to 200 m³/h (880 US gpm)

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.

A new generation of dirty water vacuum pumps

A new generation of dirty water vacuum pumps, based on the principle of the liquid ring system. This compact pump combines all performances of diaphragm, piston and centrifugal pumps and will pump continuously, by means of the specially developed rotor, on liquids, air or gasses in any mixture.

Advantages:

  • Enormous air capacity
  • Wear-resistant
  • Dry-running protection
  • For direct or V-belt drive
  • No diaphragms
  • Low weight
  • Compact design
  • Also operating without nonreturn valve

End suction centrifugal pump with horizontal inlet

DN 25-100, Up to 200 m³/h

DESMI ESL centrifugal pumps are designed for special industrial applications and meet the requirements for:

The pumps are also available in other materials such as impeller in ductile iron and various bronze alloys.

Submersible vertical screw oil spill response pump

The DOP-160 is a fully submersible vertical screw pump which is able to pump a wide variety of oils and liquids up to 30 m³/hr / 132 US gallons per minute.

Skimmer and Offloading Pump

The new model of Offloading Pump is called the DOP-200 DUAL. It is based on the internationally proven DOP-160 and DOP-250 DUAL pumps.

Double diaphragm suction pump

The pump is ideal for operation in oil spills, de- watering, construction, industry, tank cleaning and other general pumping duties.

The double diaphragm design creates a powerful suction and lift ability. These same diaphragms have a gentle pumping action that does not emulsify oil and water. This allows rapid gravity separation following pumping.

The speed and output of the hydraulically driven model is infinitely variable. It can be supplied with a hydraulic power unit. Both models are delivered fitted with oil resistant regulators.

Simplicity of design and construction provide for total ease of maintenance. This extremely rugged pump has been used worldwide for various oil recovery applications.
