A) Transport, protection, and placement
- When transporting the pump no parts of
the pump should at any time be subjected
to disproportionate loads.
- Storage of the pump must be in a dry place
with no excessive dampness. With external
storage, the pump must be stored in
watertight packaging where exposed parts
cannot come into contact with water.
- Special protection must be devoted to
bearings and neighbouring parts, which
should be guarded against moisture,
dirt, and mechanical damage. All safety
precautions that inhibit damage from
moisture and dirt must be considered.
- When connecting to the piping system, the
suction pipe must raise towards the pump,
which prevents the formation of an air cush-
ion. Likewise, the formation of mechanical
stresses on the pump and piping system
caused by the installation of mountings and
supporters must be prevented.
- When planning, care must be taken for
the right choice of defined pipe diameters,
as well as the transitions from smaller to
larger pipe diameters, where the corner
should not exceed 8 degrees. During
larger operating pressures, this should not
exceed 5 degrees.
- The architects must also foresee the instal-
lation of stop and non-return valves. Using
compensation elements will help avoid in-
conveniences during temperature changes.
The piping system must not be overloaded
due to the danger of possible leakages of
the medium, which is especially dangerous
at higher temperatures.
- Before installing the suction piping with the
pump, it is necessary to complete all safety
measures, to ensure that no impurities
and other residual solids enter the pump
and damage it. Therefore, prior to this,
it is necessary to clean and blow out the
pipe, or install a protective filter before the
pump, which will prevent the penetration
of harmful particles to the functionally
important parts of the pump.
- The pressure of the piping system should
be balanced to prevent the occurrence
of vacuum. This is implemented with a
