DESLUBE Lubrication Oil Pump

Submerged lubrication oil pump


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


DESLUBE combine the advantage of good suction ability with the nature of the centrifugal pump to adopt the system pressure fluctuations. If the lube oil pressure is dropping, a DESLUBE pump will increase the flow to reduce the risk of severe damage and eventually break down on the main engine.
