Oil pump AT2 45C
•
Pump for distillate oil EL
•
Two ratings ranges
•
Two integral pressure regulating valves
•
One normally closed solenoid valve
➄
(stage 1); and

Technical data AT2 45C:
Pump pressure range _____________________8 to 25 bar
Supply rating ________________________________50 l/h
Factory setting ______1st stage 10 bar, 2nd stage 22 bar
Setting the atomising pressure
Pressure regulating screw
➅
for stage 1:
8 to 15 bar
Pressure regulating screw
➆
for stage 2:
12 to 25 bar
Clockwise rotation
= pressure increases
Anticlockwise rotation
= pressure decreases
Priming the pump
The pump primes itself automatically on two-pipe
installations. On one-pipe installations it is only possible to
prime the pump via the nozzle line or pressure test
connection
➄
, when the solenoid valve
