1.1 Intended use
The pump is equipped with a permanent-magnet syn-
chronous drive. It is suitable for the leak-free convey-
ance of aggressive, toxic, ignitable or hot liquids.
Vertical installation of the pumps is only possible with
grease-lubricated rolling bearings or rolling bearings
with oil mist lubrication. Please consult the manufac-
turer.
The observance of the specified physical lim-
its is important for perfect functioning and safe
operation, especially with regard to explosion
protection to prevent potential sources of ignition (see
Section 2.5
):
♦
It must be ensured that the pump is always filled
with liquid during operation.
♦
For safe pump operation, we recommend a flow
rate which lies between 0.3 and 1.1 Q
opt
. The
maximum operating temperature must never be
exceeded. See
Section 2.5.7.
In case of doubt,
you must consult the manufacturer.
♦
The manufacturer must be consulted in the event
of entrainment of gas >2% as well as solids in or-
der to avoid a lack of lubrication and dry-running.
♦
The plant NPSH value (NPSHA) should be 0.5 m
higher than the NPSH value of the pump
(NPSHR). See also
Section 5.4.1.
Inadmissible modes of operation, even for a
short period, may 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 operation;
their occurrence can only be prevented by adhering to
the intended use.
Furthermore, reference is made in this connection to
the Directive 95/C332/06 (ATEX 118a) which contains
the minimum regulations for improving the occupa-
tional health and safety of the workers who may be at
risk from an explosive atmosphere.
This unit must not be operated above the val-
ues specified in the data sheet as regards the
fluid to be conveyed, flow rate, speed, density,
delivery head and operating temperature as well as
the motor rating.
The instructions contained in the operating man-
ual or contract documentation must be observed;
if necessary consult the manufacturer.
All important features are documented in the data
sheet included in the scope of delivery.
In the event of operating conditions other than those
described in the data sheet, the following are to be
checked again:
♦
design of the pump
♦
design of the accessories
♦
resistance of the materials.
