LIGHT OIL FEEDING
176: oil pump
178: solenoid valve
RL: return line
VL: suction line
VL1: working oil valve
VL2: working oil valve
SUCTION LINE LENGTHS FOR PIPE SYSTEMS
• Two-pipe siphon feed system
• Two-pipe lift system
WARNING: To calculate the length of the pipework all the straight parts, curves, up and down pipes must be taken into consideration.
The static suction height is the distance between the standing valve and the axis of the burner pump. Negative pressure must not
exceed 0,45 bar; if negative pressure is greater pump operation may become faulty, leading to an increase in mechanical noise and
perhaps even breakage. All oil ring installations must comply with the local safety rules existing in the country of installation
