1.4 Emissions
The A-valued equivalent continuous sound pressure level of the
submersible centrifugal pump type B6 is below 70 dB(A).
1.5 Sources of danger
The submersible centrifugal pump type B6 operates with a
rotating impeller. Reaching into the suction port of the pump
during operation may cause fractures of fingers and hands.
Depending on the liquid being pumped, leakage in the piping
system may cause cauterizations, poisoning etc.
Note that the pump may uncontrolled restart after voltage
breakdown (power failure, defective fuse) after remaining
switched on.
Prior to maintenance and cleaning works, switch motor off and
interrupt voltage supply (withdraw mains plug, cut out fuse).
2. Starting up
2.1 Transport/Storage
The submersible centrifugal pump type B6 is delivered, packed
in a case.
There are no special requirements for the storage of the packed
submersible centrifugal pump type B6.
2.2 Unpacking
• Open the cover of the case marked "Top"
• Pull the holding slides out of the case
• Remove pump tube and motor
The packaging may also contain any accessories ordered.
It is therefore important to check that the consignment is
complete as ordered.
2.3 Year of construction
The year of construction of the appliance can be seen on the
field for the serial number. Here are attached to the serial
number the both last digits of the year of construction, e.g.
(-10 for the year 2010).
2.4 Pump assembly
i
Important!
During mounting of the pump make sure that the
coupling insert in the coupling is arranged between
pump tube and motor.
• Place motor on the transition piece of the pump tube
• Turn motor until the coupling is operative
• By means of 4 screws, fix motor to the pump tube
2.5 Pump installation
Danger!
Liquid pumped under voltage!
Electric shocks can kill you.
Immerse the pump into the liquid to be pumped down
to the outlet only
• Connect the pump with the selected screw connections or
flanges with the piping system. The piping system may not
mechanically load the pump.
• The nominal diameters of the discharge-side connection
pipe and pump connection should at least be the same.
• Use a foot strainer when pumping liquids containing large
mechanical impurities
(see Fig. 1)
. Fibrous materials which
may cause rotating parts to seize up must be kept away from
the delivery element of the pump tube.
• If following the disconnection of the pump, there is a
greater backflow volume or higher pressure potential on
the discharge side, install a check valve in the discharge
line.
• Agitators or turbulent flows in the container endanger the
pump stability. Pumps having a nominal length of over 1.5 m,
should be additionally fixed at the pump foot
(see Fig. 2)
.
The fixing must allow the pump to expand lengthwise.
