High Capacity Diesel Separator
Diesel is the most commonly used fuel for large engines, electric generators, locomotives and commercial vehicles. For small volumes a filter or spinner type centrifuge can be used to separate coarse sludge. For larger capacities, an industrial centrifugal separator is an ideal solution. A flow-through design allows these fuel separators to remove solid and liquid contaminants on a continuous basis.
A diesel fuel centrifugal separator removes water and sludge from diesel fuel continuously. Centrifugal separators operate at high speeds to exert high centrifugal force (over 8000 g’s) to separate all free water and sediment down to 0.5 micron level. These centrifugal machines feature a heavy duty design which lends durability and high centrifugal efficiency to the separation process.
Relatively clean diesel fuel (without solids) with water contamination can be processed through a ‘manual cleaning’ type solid bowl centrifuge. The centrifugal separator will remove and discharge all free water from the fuel continuously. Any trace solids will be separated and accumulate in the centrifuge bowl which needs to be manually evacuated.
With higher sludge content and water, a ‘self-cleaning’ type centrifuge is recommended. The self-cleaning centrifuge will separate and discharge all free water from the diesel. The separated solids are automatically ejected from the rotating bowl (intermittently) by a sludge ejection mechanism. The process is controlled by a PLC control system which is used by the operator to program the sludge ejection timer based on the sludge in the dirty fuel.
Dolphin Centrifuge has diesel fuel centrifugal separators for sale. These are available in a range of capacities from 1 gallon per minute to over 80 gallons per minute. Separator modules are available as ‘plug-n-play’ packaged units with pumps, pre-filters, PLC controls, sludge collection and disposal systems. Customers can choose to buy a remanufactured Alfa Laval centrifugal separator with optional accessories for their custom designed diesel separation system.
