Function of the SEPAR 2000
The separation and filtration process takes place according to a unique and patented concept, which is applied throughout all of the range. The SEPAR 2000 series is outstanding due its small physical size in relation to the effective flow rate.
The SEPAR 2000 should be installed on the suction side of the fuel system, between the fuel feed tank and the engine mounted fuel lift pump.
Fuel enters the filter through either port A or B depending which is more convenient for installation, and using the plug provided to seal off the unused port.
From the inlet port, fuel flows through the interior vane system which imparts a circular motion to the fuel.
Still in the circular motion fuel reaches the bowl section, where, due to this centrifugal motion water droplets and heavier particles (down to 30 microns in size) are forced to the wall of the bowl, eventually settling in the bottom of the bowl.
In this stage the fuel has to pass the vane system positioned on the "outside" of the central housing. Due to the differing length of the vanes and the twofold rapid chan change of fuel flow direction, smaller water droplets and finer particles will settle on the vanes.
These settlements will agglomerate and when heavy enough fall to the bottom of the bowl. Already at this point the major portion of any contaminates in the fuel have been separated.
Just below the filter element theflow area of the filter is increased significantly thus reducing the fuel flow rate. This calming effect allows even smaller water droplets and particulate to fall out settling on the inner surfaces of the housing, forming larger droplets which eventually fall into the bottom of the bowl by gravity.
Due to the before described pre-separation process, the major portion of water and particulate present in the fuel will be in the bowl or on the inner surfaces of the filter, thus greatly extending the filter element life.
The final filtration of the remaining water and particulate still contained in the fuel will be effected by a replaceable filter element. These filter elements are produced from a special filter media and are available in diffrent pore sizes.
The clean fuel leaves the filter via outlet ports C or D (the outlet port not required should be sealed with the plug provided).
