Alfa Laval centrifuges

AlfaPure S2

AlfaPure S2 is specifically designed for cleaning process fluids used in the metal working industry.

During the centrifugal separation process inside the separator bowl of AlfaPure S2, the heavy particles of the operating liquids are pressed against the wall of the separator and are then conducted into a sediment tank. During this process different liquids are divided and leave the separator via separate outlets.

AlfaPure S2 is available for the application as a concentrator, clarificator or purifier. As a concentrator it removes tramp oil, grease and solids from water-based cooling lubricants and washing liquids. The clarificator is a two-phase design that removes fine solids from water-based cooling lubricants or washig liquids. The purifier serves for the cleaning of mineral oils by removing water and fine solids which prevents wear, abrasion and malfunctions.


  • Fast and simple installation
  • Less than 1,3 m² of storage space for tanks with a volume of up to 100 m³
  • EPC 60-cotrol system with a clearly arranged operator interface guarantees a simple operation
