Design data:
Total consumption of the connected engines added with
the flush quantity of the automatic filter (1F08)
Capacity
1.6 MPa (16 bar)
Design pressure
0.7 MPa (7 bar)
Max. total pressure (safety valve)
100°C
Design temperature
1000 cSt
Viscosity for dimensioning of electric motor
Pressure control valve, booster unit (1V03)
The pressure control valve in the feeder/booster unit maintains the pressure in the de-aeration
tank by directing the surplus flow to the suction side of the feed pump.
Design data:
Equal to feed pump
Capacity
1.6 MPa (16 bar)
Design pressure
100°C
Design temperature
0.3...0.5 MPa (3...5 bar)
Set-point
Fine filter (1F05)
The fuel oil fine filter is a full flow duplex type filter with steel net. This filter must be installed
as near the engine as possible.
The diameter of the pipe between the fine filter and the engine should be the same as the
diameter before the filters.
Design data:
according to fuel specifications

Automatic filter, booster unit (1F08)
It is recommended to select an automatic filter with a manually cleaned filter in the bypass
line. The automatic filter must be installed before the heater, between the feed pump and the
de-aeration tank, and it should be equipped with a heating jacket. Overheating (temperature
exceeding 100°C) is however to be prevented, and it must be possible to switch off the heating
for operation on MDF.
