3.5 Safety instructions relevant for operation
If hot or cold machine components involve
hazards, they must be guarded against acci-
dental contact.
Guards for moving parts (e.g. coupling) must not
be removed from the machine while in opera-
tion.
Any leakage of hazardous (e.g. explosive, toxic,
hot) fluids (e.g. from the shaft seal) must be
drained away so as to prevent any risk to per-
sons or the environment. Statutory regulations
are to be complied with.
Hazards resulting from electricity are to be
prevented (see for example, the VDE Specifica-
tions and the bye-laws of the local power supply
utilities).
The pumps are only secured safely if properly
attached to the floor.
The female threads on the motor MUST NOT be
used to lift the entire pump and motor assembly.
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
The pumps must be properly fastened. The pipe-
work must be installed so that no distortion of the
pump can occur. The fluid inlet is on the face side
of the flange-connected pump mechanism. The
clearance between the suction opening and the
tank floor should be large enough to prevent the
suction opening from becoming blocked even if the
coolant is heavily polluted and the pump has not
been operated for long periods.
In order to reach the maximum flow rate it is rec-
ommended that the pipe diameter is as close as
possible to the nominal pump connection diameter.
Avoid the introduction of pipe bends (no angled
sections).
The installed pipes must be rated for the hydraulic
pressures which occur during operation. The posi-
tions of the foot and pressure connection can be
moved around the circumference to 3 different
positions.
Touching the rotating parts is forbidden!
The pump must be mounted in that way that
rotating parts under the cover of the coolant
tank can not be touched!
ATTENTION
Maximum tightening torque for piping connec-
tions is 120 Nm!
When installed the space around the pump
must be large enough to provide sufficient
cooling of the motor.
The pump must never under any circumstances
be used as a point for securing the piping. No
forces or torques from the piping may be al-
lowed to affect the pump. Pipes must be inter-
cepted directly before the pump and connected
with no tension.
