For oil consumer installations, the following mean flow rate is applicable pursuant to
DIN 4755:
Taking into account the length of the suction
line, the geodesic height, the suction height, and
the fuel oil volume flow rate, the following can
be recommended for selecting the piping:
• Lower flow rates in suction mode will result in an undesired formation of bubbles.
• Piping with inner diameters (ID) of less than 4mm is not recommended!
Maximum total pressure loss of all fittings in the suction line = 0.4bar
The pressure loss of the GS Pro-Fi 3 depending on the fuel oil volume flow rate and the filter
insert used can be found in the diagram:
Filter insert
There is no such thing as a universal filter insert. The filter insert should be selected
based on the specifications of the burner manufacturer according to filter mesh and
the present operating conditions.
Regarding oil consumer installations with so-called "Low-NOx burners" and burners
with lower heat outputs, the GOK filters "opticlean 2.0" (fine filtration) with a mesh
width of < 35μm are recommended.
