These starting and operating instructions are applicable to electric
submersible sludge pumps specified on the cover. The pumps are intended
for pumping water that may contain abrasive particles.
DANGER!
KG range has a cutting system at the inlet to the
hydraulics, which cannot be covered as it would obstruct
functioning.
DANGER!
The pump must not be used in an explosive or flammable
environment or for pumping flammable liquids.
The pumps conform to the EU machine directive. See rating plate.
The manufacturer guarantees that a new pump will not emit airborne noise
in excess of 70 dB(A) during normal operation, when either fully or partially
submerged.
Limitations
Immersion depth: up to 10 m (33ft).
Liquid temperature: up to 40°C (105°F).
Pump variants Impeller type
Example of type designation:
KG 30 W- CA2
W = Single-phase
= 3-phase
Motor
Single-phase AC motor or 3-phase squirrel-cage induction motor for 50 or
60 Hz. Degree of protection IP 68.
Level control
Some pumps can be equipped with float switch for automatic level control.
Motor protection
The stator may be equipped with built-in temperarure sensors.
The pump can be transported and stored either vertically or horizontally.
Make sure that it is securely lashed and cannot roll.
CAUTION!
The pump must always rest on a firm surface so that it will
not overturn. This applies to all handling, transport, testing
and installation.
NOTE!
Always protect the cable end so that no moisture will penetrate into
the cable.
Water could otherwise seep into the terminal compartment or into
the motor through the cable.

CAUTION!
The pump must not be run if it has been partially
dismantled.
CAUTION!
Should a person come in contact with either the pump or
the pumped medium, for example on construction sites, in
agriculture etc, an earth leakage detector (ELCB) must be
used.
A safe distance of 20m should be maintained between the pump and
people.
The pump must not be used in swimming pools. Special regulations
apply for swimming pools.
Electric cable
10 m (33 ft) of HO7RN-F or equivalent cable. If the cable is longer, the
voltage drop must be taken into account.
Technical data
See the table on page 26 (at the end of the manual).
The significance of the text in the table heading is as follows:

CAUTION!
Always lift the pump by the lifting handle - never by the
motor cable or hose.
If the pump is stored for a longer period of time, protect it against dirt and
heat.
CAUTION!
Before lifting the pump, check the condition of the lifting
handle and make sure that its screws are securely
tightened.
