General safety information
The operator must read and follow the operating
instructions before starting the motor.
. The motor is not explosion proof. It is not allowed to
be operated in explosion hazard areas.
. The motor must not be used to pump flammable
liquids.
3. The motor may only be operated in an upright
position.
4. The motor must not be immersed in the liquid being
pumped.
5. Ensure that all connections and fittings are properly
tightened.
6. The voltage specified on the rating plate must match
that provided by the mains/battery.
7. Ensure that the motor is switched off before connec-
ting to the electricity supply.
8. Check the low voltage release if this is required for a
safe operation.
9. Do not operate motor without pump tube.
0. Do not stop the motor by using the speed controller.
Uncontrolled restart possible.
The national accident prevention regulations must be
observed without fail.
1. General
An electric drum and container pump comprises motor
and pump tube to suit the particular application. Motor
types MA II and MI 4 with the various pump tubes are
suitable for pumping non-flammable, aggressive, thin-
bodied liquids. Motors are
not
approved for use in or on
swimming pools, garden ponds, etc.
1.1 Scope of supply
Check that the consignment is complete as ordered.
2. Motor types
The pump motors are single-phase series-wound motors
with the operating voltages, input ratings and frequencies
specified according to
table 1 and 2 (see page 10)
.
The input motor rating and the required voltage and
frequency are specified on the rating plate. Check that
the specified voltage and frequency match the available
mains supply.
Vibrations are transmitted to the operator as he holds the
motor in his hand during operation. The upper limbs are
exposed to an acceleration of less than .5 m/s².

3. Starting up
3.1 Connection to the pump tube
The motor is mounted on the pump tube. The upper
coupling on the motor engaging in the coupling of the
pump tube. The motor and pump tube are then firmly
connected by means of the handwheel (right-hand th-
read)
(see Fig. 1)
.
3.2 Electrical connection
(see Fig. 2)
The voltage specified on the rating plate must match that
provided by the mains/battery.
The on/off switch must be set to 0 before
connecting to the mains/battery.
DC motors can be connected in any required polarity to
the power supply.
