3.6 Safety instructions relevant for mainte-
nance, inspection and assembly work
Any work on the machine shall only be performed
when it is at a standstill, it being imperative that the
procedure for shutting down the machine described
in this manual be followed.
Pumps and pump units which convey hazardous
media must be decontaminated.
On completion of work all safety and protective
facilities must be re-installed and made operative
again.
Prior to restarting the machine, the instructions
listed under “Start up” are to be observed.
3.7 Signs on the pump
It is imperative that signs affixed to the machine,
e.g.:
•
arrow indicating the direction of rotation
•
symbols indicating fluid connections
be observed and kept legible.
3.8 Unauthorized alterations and production
of spare parts
Any modification may be made to the machine only
after consultation with the manufacturer. Using
spare parts and accessories authorized by the
manufacturer is in the interest of safety. Use of
other parts may exempt the manufacturer from any
liability.
4 Transport and storage
Protect the pump against damage when transport-
ing.
The pumps may only be transported in a horizontal
position and hooks or straps must be attached on
the motor and pump end.
Do not use the pump shaft for connecting any
transportation aids such as hooks or straps.
Pumps must be drained prior to their storage.
Store pump in dry and protected areas and protect
it against penetration of foreign bodies.
Always store pump above the freezing point!
5 Installation and Connection
5.1 Mechanical installation
During any assembly or disassembly process the
pumps must be secured against tipping trough
ropes for example at all times.
Pumps must be mounted securely. Piping, tank and
pumps must be mounted without any tension.
The inlet is at the bottom of the immersed pump
body. The distance between the inlet and the tank
bottom must be so large that the inlet can not be
blocked by deposits during longer shutdowns.
To obtain the full flow rate it is recommended to
choose for the pipework the nominal bore diameter
of the pumps cross section for connection. There-
fore pipe bends should be used, not pipe angles!
The pipework must be qualified for occuring hy-
draulic pressure.
ATTENTION
Maximum tightening torque for piping connec-
tions is 200 Nm!
When installed the space around the pump
must be large enough to provide sufficient
cooling of the motor.
Do not prop up the pressure line via the joining
socket.
The pump must be mounted in that way that
rotating parts under the cover of the coolant
tank cannot be touched!
