DETERMINATION OF THE FLOW RATE, THE PIPE DIAMETER, AND THE PRESSURE
LOSS
Flow rate
The outlet pipe must be dimensioned pursuant to DIN 4755 in such a way that the mean flow
rate of the fuel oil is between (0.2 and 0.5) m/s. In the event of too large a pipe diameter with
low flow rates, undesired formation of gas bubbles may occur.

For supply / oil systems, 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 of less than 4mm is not recommended!
Maximum total pressure loss of all fittings in the suction line = 0.4bar
