VISCOSITY - TEMPERATURE DIAGRAM

AUXILIARY PUMP (SEE 8511/6 - 8513/7)
In some cases (excessive distance or difference in level, or excessive
viscosity and in any case when using "D" dense version burners) it
is necessary to install a "loop-type" supply system with an auxiliary
pump, thus avoiding direct connection of the burner pump to the tank.
In this case, the auxiliary pump can be started when the burner
starts and stopped when it stops.
The electrical connection of the auxiliary pump is made by connecting
the coil (230V), which controls the pump remote control switch,
to terminals "N" (input terminal board of the equipment) and "L1"
(downstream the motor remote control switch):
Always follow the instructions below:
• the auxiliary pump must be installed as close as possible to the
liquid to be aspirated.
• the head must be suitable for the relative plant.
• we recommend a flow rate that is at least equal to the flow rate
of the burner pump.
Pumping limit
Viscosity range for atomization
• the connection pipes must be dimensioned based on the flow
rate of the auxiliary pump.
• do not wire the auxiliary pump directly to the remote control
switch of the burner motor.
