Separ 2000 Water Separator & Fuel Filter
The SEPAR 2000 is a water separator and fuel filter for light diesel fuel (petrol models are available). An entirely new multistage centrifugal system ensures a 100% solution to the problem of water and particulate in fuel.
SEPAR 2000 offers:
In 1992 Willibrord Lösing Filter-Technik designed the next generation of SEPAR Filters called the SEPAR 2000 Series of fuel filters, as an effective system for the separation of water and particulate from fuel. Both water and particulate matter can result in high wear and tear of fuel pumps and injectors, resulting in reduced reliability and expensive engine repairs.
SEPAR 2000 Main Features
- Available with various flow rates from 1 to 260 l/min. Thereby offering fuel filters for an engine performance range of 5 to 10,000 kw.
- Compact size, various ports, simple installation.
- High separation efficiency of water which is contained in the fuel. (No water could be proven according to RTÜV testing.)
- Due to the backflushing extended service time of the filter elements.
- The SEPAR 2000 Filter protects the injection pump and injection nozzles.
- Easy maintenance of the SEPAR 2000 filter
Function of the SEPAR 2000
The separation and filtration process takes place according to a new, unique and patented concept, which is applied throughout all of the range. The SEPAR 2000 series is outstanding due to 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 (see below) depending which is more convenient for installation, and using the plug provided to seal off the unused port.
SEPAR 2000 Flow Scheme
Stage 1 From the inlet port, fuel flows through the interior vane system which imparts a circular motion to the fuel.
Stage 2
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.
Stage 3
In this stage the fuel has to pass through the vane positioned on the "outside" of the central housing. Due to the differing length of the vanes and the twofold rapid change of the 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.
Stage 4
Just below the filter element the flow 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 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.
Stage 5
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 different pore sizes. The clean fuel leaves via outlet ports C or D (the outlet port not required should be sealed with the plug provided).
Installation of the filter
The SEPAR 2000 can be easily installed. 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.
-
Install the SEPAR 2000 filter in an accessible position. (Any other primary filter has to be removed from the suction line.)
-
The SEPAR 2000 housing has two inlet and two outlet ports to give options on installation position.
- The ideal position for the filter is at the same height as the lift pump. However if the top of the fuel tank is above the this position a "full flow" ball valve should be fitted, before the filter so that the fuel flow can be shut off to allow filter maintenance.
- In application where the fuel filter is below the filter it is still advisable to install a "full flow" ball valve to prevent fuel draining back into the fuel tank. After filter installation on system without a positive head of fuel, remove the filter lid and fill with fuel to assist in priming the system.
- Avoid sharp 90 degree bends on the fuel system piping as these increase system pressure drop, as does any reduction in the internal diameter of fuel piping.
- Please use only fittings with o-ring seals (contained in our program of accesories). Do not use hollow bored screws with copper rings as they are difficult to seal and result in a high pressure drop.
- Please consider
a clear space of 60mm above the housing/filter lid to replace the filter
element.
Important:
Only clean diesel fuel should be used to clean the clear plastic bowls, certain cleaning materials can attack the plastic material and have a detrimental effect.
The SEPAR 2000 filters are available in special biodiesel (Cannola) resistant versions on request.

SEPAR 2000 Backflushing Process
Switch off the engine. Open the bleed valve on top of the filter lid (note: If fuel is above the top of the SEPAR filter close the fuel feed valve if fitted) then open the drain valve fitted to the bowl. The clean fuel between the filter lid and the clean side of the element will flush back through the filter element and "wash off" the collected water droplets and particles from the filter media. At the same time fuel that is draining from the bowl is carrying contaminates out with it. Close the drain valve, open the fuel feed valve and prime the fuel system. Close the bleed valve. Now the engine can be re-started.
If the engine is not able to reach maximum revolutions then the element requires to be replaced.
