Basically, all work on the machine is to be performed while the machine is not
in operation. The sequence for shutting the machine down described in the
Operating Instructions must be strictly observed. Pumps or pump units handling
hazardous liquids must be decontaminated.
Immediately upon completion of the work, all safety and protective equipment
must be restored and activated.
Before restarting the machine, all points contained in chapter “Initial Start-up”
must be observed.
2.7
Unauthorized Changes and Manufacturing of Spare Parts
Any conversion or changes of the machine may only be undertaken after
consulting the manufacturer. Original spare parts and accessories authorized
by the manufacturer guarantee operational safety. Using non-authorized parts
may void any liability on the part of the manufacturer in case of consequential
damage.
2.8
Unauthorized Operation
The operational safety of the machine delivered is only guaranteed if the
machine is used in accordance with the directions contained in Section 1 –

Description
The series B 9 is exclusively designed for the circulation of brine for wet salt
road clearance which is to be used together with a special unit. The plastic
parts in contact with the transported medium are mostly of glass fibre reinforced
polypropylene PP GF 30 and thus possess excellent corrosion resistance
against the transported medium. The pump housing does not contain any
inserts, therefore it can easily be recycled.
The motor shaft also serves as the pump shaft on which the impeller is moun-
ted. The seal for the shaft is a bellows-type mechanical seal arranged on a
plastic impeller hub. This guarantees a positive electrical separation between
the transported medium and the electric motor. Because of the pump’s close
coupled design, a minimum of space is required. The pumps are driven by
three-phase or single-phase motors. Integrated in the pump housing is a
strainer basket (143), which keeps coarse impurities from the pump’s interior.
