4 Installation
4.1 Safety regulations
Equipment which is operated in potentially
explosive areas must satisfy the explosion
protection regulations.
It is imperative to observe the safety regulations con-
tained in the respective installation and operating
manuals.
With magnetic drive pumps MNK-X, MNK-XB:
People with a pacemaker are at risk from the
strong magnetic field of the magnetic drive. It
may be life-threatening for them to stay at a
distance of less than 500 mm from the pump.
5 Commissioning / Shutdown
The general commissioning/shutdown procedures
have already been described in the installation and
operating manuals of the pumps of the series MNK,
MNK-B, SCK. They relate, for example, to work or
inspections of the bearing pedestal, coupling and mo-
tor.
5.1 Initial commissioning
Normally, the pumps have already been test-run with
water. Unless special agreements have been made,
there could still be residual amounts of water in the
pump. This must be noted in view of a possible reac-
tion with the medium.
5.2 Shutdown
Only close the suction line if the pump is to be
evacuated or dismantled.
If the pump is to be evacuated or flushed,
observe the local regulations. If the pump is
to be returned to the company's own work-
shops or the manufacturer's, it must be cleaned es-
pecially thoroughly.
See also Section 3.1.
5.3 Improper operations and
their consequences
Inadmissible modes of operation, even for a
short time, can result in serious damage to
the unit.
In connection with explosion protection, potential
sources of ignition (overheating, electrostatic and
induced charges, mechanical and electric sparks)
may result from these inadmissible modes of opera-
tion; their occurrence can only be prevented by ad-
hering to the intended use.
Depending on the design selected, refer to the rele-
vant operating manual MNK, MNK-B or SCK.
6 Maintenance
6.1 Notes on dismantling
All repair and maintenance work is to be performed by
qualified staff using appropriate tools and original
spare parts.
Is the necessary documentation available?
Has the pump been taken out of operation, evacuated
and flushed correctly?
See also Section 5.2.
The pump is dismantled and assembled in accor-
dance with the operating manual.
The difference between a standard pump and a vor-
tex pump is:
vortex impeller 230
a distance ring 504/3 instead of a housing gasket
longer hex. screws 901/3 owing to the larger dis-
tance in front of the impeller.
