MAXIMUM LENGTH OF SUCTION LINES FOR TWO-PIPE SYSTEM
Two-pipe siphon feed system
H
To correct length of pipes is calculated by summing up the length of all vertical and horizontal right sections
and bends. The static suction head will be the distance between the non-return valve and the
burner's pump axle. The depression must not be greater than 0.45 bar; should it be higher, some damages
could occur to the pump, with consequent increase in mechanical noises and ,eventually, a failure.
