Technical information Diaphragm anti siphon valve ... - Oventrop

Max. length of suction pipe [m]
The chart below is a guide to the maximum length of the
suction pipe depending on the flow capacity of the oil and
the inner pipe diameter. It is assumed that the safety height
The stated values are valid for a suction pipe without pipe
bends/elbows, including the resistance values of the valves
(diaphragm anti siphon valve and filter/”Toc-Duo”) illustrated
in the example of installation. When using the maximum
possible length of the suction pipe, then the burner pump
has to produce an underlying pressure of about –0.4 bar.

Flow capacity of oil [l/h]
Pipe bends/elbows, isolation- and change-over valves or
other installations in the suction pipe between the diaphragm
anti siphon valve and the burner as well as oil of low
temperature (underground tanks, unheated storage rooms,
pipes installed outside, etc.) will mean additional pressure
loss. Any such installations can reduce the maximum
possible length of the suction pipe considerably, when
compared with the values illustrated in the chart.
