1.1 Intended use
The pump is equipped with a permanent-magnet
synchronous drive. It is suitable for the leak-free con-
veyance of aggressive, toxic, ignitable or hot liquids.
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.
♦ The flow rate must lie between 0.3 and 1.1 Q
opt
. It
is necessary to consult the manufacturer for opera-
tions outside this range. The specified maximum
operating temperature must not be exceeded. See
Section 2.5.6.
♦ The manufacturer must be consulted in the event
of entrainment of gas or solids in order to avoid a
lack of lubrication and dry-running.
♦ The plant NPSH value (NPSHA) must be 0.5 m
higher than the NPSH value of the pump
(NPSHR). See 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
liquid to be conveyed, flow rate, speed, den-
sity, 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.
