3.3.2. Motor
The motor consists of an engine block and the engine
shaft with the impeller assembly. The circuit for power
supply is designed for the maximal mechanical perfor-
mance according to the characteristics or the nameplate
of the pump. The cable inlets as well as the circuit are
sealed resistant to jet water towards the pumped medi-
um. The shaft bearing is carried out by means of robust,
maintenance-free and permanently lubricated antifriction
bearings.

3.3.3. Monitoring devices

Temperature sensor
All pumps in alternating current version are provided with
a temperature sensor set in the motor winding, which
switches the motor off in the event of overheating of the
winding.
Checking direction of rotation
No check is required for single-handed motors, since
these always run in the correct direction.
Three-phase motors have the correct direction of rotat-
ing if connected to an anti-clockwise rotating field (U, V,
W -> L1, L3, L2). For smaller pumps the check can be
carried out by observation of the start-jerk. For this, place
the pump vertically onto the floor, slightly onto the edge
and switch on for a short time. When seen from above,
the pump rebounds slightly clockwise in correct direction
of rotation.
The direction of rotation is correct if the pump moves
clockwise, since the motor starts anti-clockwise when
seen from above.
Warning - rotating impeller!
Do not touch the rotating impeller or do not reach the
pump chamber through the pressure socket! Never
put your hands into the pump chamber or touch the
rotating parts in operating mode. Switch the machine
off and let the rotating parts come to gridlock before
carrying out maintenance work or repair work!
Furthermore it is possible to check the direction of ro-
tation with a 'motor and phase rotation indicator'. This
measuring device is held towards the engine block of the
running pump from externally and shows the direction of
rotation by means of LED.
