▪ The nominal diameters of the pipelines are at least equal to the nominal
diameters of the pump nozzles.
▪ The general arrangement drawing shows which pipes, valves and instruments are
included in our scope of supply and how they are arranged.
▪ All pipes in the baseplate area have been completely mounted at the factory.
▪ Make and adapt any possibly required connecting pipes in accordance with the
general arrangement drawing (offset at flange connections and pipe unions is
not permitted.).
▪ Pipes supplied by KSB have been cleaned and closed. Nevertheless their interior
must be checked for impurities which might have been caused afterwards and be
cleaned, if required.
▪ As a general rule, pipes made on site must be cleaned prior to final mounting.
▪
Do not remove blind flanges or covers on pump nozzles and pipe connections
including any packaging with desiccants possibly attached to them until
immediately before the relevant pipes are connected.
5.16.2 Cleaning the piplines
CAUTION
Solids inside the pump or in the pipelines.
Increased wear or blockages!
▷ When flushing the piping, the pump must as a rule be protected against
welding beads, scale and other impurities.
▷ Use pipe bypasses or filters to prevent solids from entering the pump.
CAUTION
Cleaning with a high-pressure steam-jet air ejector
Destruction of plastic parts through high-pressure steam-jet air ejector.
▷
Never clean the cooling circuit with a high-pressure steam-jet air ejector.
Permissible cleaning methods:
▪ The pipes may be blown through with compressed air.
▪ If the pipes have been welded with forming gas, they may be cleaned using a
high-pressure steam-jet air ejector at a steam temperature of at least 110 °C.
