ENGLISH
Dangers caused by electrical energy are to be
excluded. Directives issued by the VDE [German
Association of Electrical Engineers] and the local
electricity supply companies are to be observed.
2.5 Safety information for inspection
and assembly
The operator is responsible for ensuring that
inspection and assembly are carried out by
authorised and qualified personnel who have
studied the operating instructions closely.
Work on the pump/machinery should only be carried
out when the machine has been brought to a
standstill.
2.6 Unauthorized modification and manufacture
of spare parts
Alterations to the pump or installation may only be
carried out with the manufacturer's consent. The use
of original spare parts and accessories authorised
by the manufacturer will ensure safety. The use of
any other parts may invalidate claims invoking the
liability of the manufacturer for any consequences.
2.7 Unauthorised operating methods
The operating safety of the pump or installation
supplied can only be guaranteed if it is used in
accordance with paragraph 1 of the operating
instructions. The limiting values given in the
catalogue or data sheet must neither be exceeded
nor allowed to fall below those specified.

3. Transport and interim storage

ATTENTION! The pump may only be trans-
ported/suspended on the handle
provided for transport. It is to be
protected against mechanical damage
and may not be exposed to tempera-
tures outside the range 0 °C to +50 °C.
4. Product and accessory
description

4.1 Pump description

The housing of the submersible motor-driven pump
is made of plastics. The electric motor is protected
against the pump chamber by a shaft seal ring to
seal off the Motor against oil chamber and a
mechanical seal to seal off the oil chamber against
12
water.
The motor is cooled by the surrounding pumping
medium.
The pump is mounted on the bottom of a shaft.
The water is pumped into the channel a hose or
a permanently installed pipe. The pumps of series
TM / TMW operate automatically by means of a float
switch which switches the pump on at a specific
water level "h" (fig. 1) and off at a minimum water
level "h1".
ATTENTION! Do not allow the pump to run dry.
Dry running destroys the mechanical
seal between pump and motor.
Maintain minimum water level "h1"
(see table 1.2.2 and fig. 1)!
The AC motors are equipped with a built-in motor
cut-out, which switches the motor off if it overloads
and automatically switches it back on again once it
has cooled down.
The pumps have a vent hole between the bottom
and top pump sections, so that during operation
water (air) escapes through the slit in the suction
strainer. This bypass prevents air from collecting
underneath the flap trap, thereby guaranteeing the
operational safety of the pump.
TMW: The pumps are equipped with built-in non-
return devices.
For waste water with suspended and
settlable solids, the submersible motor-
driven pump was fitted with a whirl
device on the suction strainer. Precipitating
impurities are constantly whirled up in the
suction area of the pump and pumped out
with the water. This largely prevents the
pump shaft from silting up with all the
unfavourable consequences such as pump
blockages and bad smells.
TM: TM pumps are not equipped with whirl
device and non-return device.
The individual equipment variations can be found in
the table under 1.2.2.
The pumps are operated by connecting the
earthing-pin plug.
If the dirty water drain does not permit interruption,
nd
a 2 pump (automatic reserve pump) in connection
with the required switchbox (accessory) increases
operational safety if there is a fault in the 1
st
pump.
