Rosenbauer – NAUTILUS 8/1
To ensure safe and trouble-free operation of the submersible-type pump, the
following checks should be performed at least once a year:
▪
Visual check of cable and grommet
▪
Functional check of mechanical shaft seal (as described in item 6.2.)
▪
During trial run, check the shaft seal for unusual noise
The NAUTILUS 8/1 was designed not to need any consumables throughout its
working life.
6.2. Checking the mechanical seal
The NAUTILUS 8/1 is equipped with a
double seal system. To check the
functionality of the mechanical seal
(primary seal), seal the discharge
outlet with a blind plug or, a
2,5 „ ball-type valve, and place the
NAUTILUS 8/1 in a container filled
with approx. 30 cm of water; switch
on the pump and allow to run for a
few minutes. If water escapes from
the control aperture at the top of the pump, the mechanical seal is worn and
must be replaced by an authorized repair center.
Also listen for unusual noises which may indicate bearing damage.
6.3. Removing the suction strainer
Before removing the suction strainer base, always disconnect the power cable
from the power supply to avoid inadvertent enabling of the pump. Before star-
ting work, make sure that all rotating parts are stationary.
CAUTION: Operation without a suction strainer base and/or suction
strainer grid is not permitted.
