Magnochem-Bloc
If there is no data sheet or if the pump is part of a pool of pumps, contact KSB for
the maximum permissible operating temperature.
2.9.3 Monitoring equipment
The pump (set) must only be operated within the limits specified in the data sheet
and on the name plate.
If the system operator cannot warrant compliance with these operating limits,
appropriate monitoring equipment must be used.
The operator shall determine whether monitoring equipment is required to ensure
that the pump set functions properly.
Take into account the following risks when selecting suitable monitoring equipment:
Cooling flow interrupted An insufficient cooling flow or failure of the cooling flow can be caused by the
following:
▪ Fluid properties
▪
Pressure and/or barrier fluid pressure too low
The following malfunctions may occur:

Internal circulation External circulation Low-boiling fluids Dead-end configuration
Blocking of bores within the pump (e.g. casing cover or shaft) ✘ ✘ ✘ ✘
Blocking, clogging, gumming up of the piping (e.g. auxiliary feed lines) - ✘ - ✘
Blocking, clogging, gumming up of the filter (e.g. ring filter, main flow filter) ✘ ✘ ✘ -
Failure or insufficient heat exchanger performance - - - ✘
Failure or insufficient barrier fluid system function - ✘ - ✘
An insufficient cooling flow or failure of the cooling flow may lead to an
impermissible temperature rise.
Inner and outer rotor out of
synchronisation
Overloading, overheating or non-compliance with the design data may cause the
inner and the outer rotor to drop out of synchronisation. Thermal energy produced
inside the containment shroud or at the outer rotor may also result in an
impermissible temperature rise.
Leakage of fluid handled If a defect in the containment shroud (rare defect) will result in leakage of a fluid
whose critical properties might pose a hazard to staff and the environment, leakage
monitoring must be provided in combination with a pump version with leakage
barrier. Any interaction of the fluid handled with the pump materials shall be taken
into consideration if necessary.
