The KFWA is used for fuel filtration and separation. The system is delivered in two parts (pump module/treatment module) for easier adaptation to the on-site conditions. The geared pump pumps the medium to the treatment stage, where the fuel is filtered and separated. Separated water is detected by a probe and discharged automatically. The soiling of the treatment stage is monitored using the differential pressure. If the differential pressure reaches 2.0bar, the main alarm appears (preliminary alarm: 1.8 bar) and the interior treatment element must be replaced. If it is not possible to replace the element despite the alarm message, the pressure continues to rise until the relief valve fitted to the pump opens the bypass. The fuel then flows unfiltered past the treatment stage, and the engine filters are then responsible for filtration.
In this case, the fuel is no longer dewatered due to the bypass. The KFWA BY system has been designed for use between storage tank and day tank.
