Pumping
NOTICE
Do not operate the pump in the cavitation area!
Cavitating of the pump is perceptible as a noise (similar to pebbles being
pumped).
Never operate the portable fire pump without suction head or suction
filter.
► Start up the portable fire pump as described in the chapter
"Priming from an open water source."
The highest delivery pressure of the pump, indicated at the pressure gauge,
is 17 bar (P28) with a maximum inlet pressure of 17 bar.
The supply pressure indicated at the water pressure vacuum gauge (P30)
must not drop below 1 to 2 bar; otherwise, the supply hose will collapse and
restrict water flow.
The maximum inclination of the portable fire pump only applies when the oil
is filled to the maximum level.
If water is not discharged when the pump is running, the water in the pump
and the pump itself heats up. This can be prevented by regular water dis-
charge.
Do not use the portable fire pump in potentially explosive atmospheres!
