Separ SWK2000/130 and SWK2000/130/2 Simplex



The largest single filter in the range is the SWK2000/130MK, with a capacity of 130 lit/min (7800 lit/hr), whereas its "double" version, the SWK2000/130/2MK has twice that capability, 260 lit/hr (15600 lit/hr). Capable of handling flow rates up to 7800 litres per hour (130 litres per minute), with 2 inch input and output nut and olive connections, the SWK2000/130U offers the most efficient unit, with the highest potential fuel flow rate. As with other units in the SWK2000 range, it can be supplied to filter bio-diesel if required.

  • Highest fuel flow rate  vs minimal restriction (low Delta P)
  • Long-life filter elements available in either paper or stainless steel 
  • Easy installation
  • Simple operation
  • 5 stage filtration 
  • Option for petrol and bio-diesel applications
  • Suction side centrifugal filter

How does it work?

Complete cleansing of the fuel is possible thanks to the Separ SWK 2000 series unique five-stage purification and separation process.

SWK2000 flow diagram

  1. fuel flows through the stationary aluminium centrifuge, which imparts a rotary, motion to the fuel flow
  2. the fuel exits the centrifuge where larger particulate and water droplets are separated into the bottom of the bowl by precipitation
  3. fuel flows through the second centrifuge, with the lower vane creating a partial vacuum, drawing smaller droplets and particulate down the vane into the bowl
  4. droplets of water and dirt coalesce on the upper surface during the forth stage, and when heavy enough fall back into the bowl
  5. fuel passes vertically through a filter element that removes any remaining water and particulate greater than an optional 10, 30 or 60 microns

The results

  • separ swk2000 elementClean fuel then flows to the engine fuel system
  • Separated water is contained in the bowl
  • Contaminations including fuel bug is captured in the element within the Separ Filter

Here is an example of an element from a SWK2000 which has encountered some dirty fuel, which includes a bacterial infection caused by water contamination. The element on the left is a clean element, the right is one which has collected contamination from the fuel.
