The rated (nominal) values can be found on the type plate.
Nominal input data relate to:
•
an ambient temperature of -20 °C to 40 °C
• maximum temperature of the medium 40 °C
• continuous operation S1 and
• rated supply voltage
The connecting cables are designed for rated operation
where they are:
•
separately routed,
• permanently submerged and/or attached to surfaces
and/or passing through air, and
• at a maximum ambient temperature of 40 °C
If the routing and/or ambient temperature of the connect-
ing cables differs from this, the standards and regulations
applicable at the installation site must be observed. If the
type of operation and/or rated power supply is different,
the tolerances specified in EN 60034 must be observed
and the installation adjusted in accordance with the stan-
dards and regulations applicable at the installation site.
Note:
Conditions at the installation site must conform to all de-
tails on the rating plate.
In the case of uncertainty, the manufacturer must be con-
sulted before commissioning.
3.3.2. Motor
The three-phase asynchronous motor is made from sheet
metal with a double-varnished winding wire as well as the
motor shaft with rotor package. The power supply cable is
designed for the maximum mechanical load and is sealed
against water pressure from the pumped liquid. The mo-
tor cable lead connections are sealed from the pumped
liquid as well. The bearings used are permanently lubricat-
ed maintenance-free antifriction bearings.
All models are available with explosion proof motors ac-
cording to ATEX Ex II 2 G EExd.

seal conditions sensor (&stator room)
HU...(S) Fully submerged motor, Temperature monitoring in the
winding, Oil chamber seal conditions sensor
(&stator room)
HL...(S) Fully submerged motor, closed liquid cooling, Tempe-
rature monitoring in the winding, Seal probe leakage
chamber (&stator room)
H...EX Temperature monitoring in the winding, Explosion
proof (only 50Hz)
H.../C(S) EX Temperature monitoring in the winding, Oil chamber
seal conditions sensor and motor connecting chamber

HU...(S) EX Fully submerged motor, Temperature monitoring in the
winding, Oil chamber seal conditions sensor
(&stator room), Explosion proof
HL...(S) EX Fully submerged motor, closed liquid cooling,
Temperature monitoring in the winding, Seal probe
leakage chamber (&stator room), Explosion proof
Temperature Sensors
All pumps have a set of temperature sensors built in the
stator windings. The contact of these sensors opens in
case of overtemperature and switches off the motor pow-
er supply.
Standard models have the sensors connected to the mo-
tor power supply cable the wire ends marked T1 and T3.
