Installation and service by qualified personnel only!
1.1
Uses
The pumps in the VC series are suitable for pumping chemical-
ly neutral, lightly soiled wastewater, condensate and clear flu-
ids containing solids of 5 to 7 mm Ø from pump shafts from
boiler and heating installations and basements at risk of floo-
ding.
These pumps must not be used:
– to pump raw sewage containing faeces
– in areas where there is a risk of explosion
– to pump drinking water.
Local regulations must be observed.

2 Safety
These instructions contain important information which must
be observed when installing and operating the pump. These
operating instructions must therefore be read by the installer
and the responsible operator before assembly and commis-
sioning. In addition to the general safety instructions laid down
in the Safety section, the special safety instructions laid down
in the following sections are also to be observed.
2.1

ATTENTION!
2.2
Staff training
The personnel installing the pump must have the appropriate
qualifications for this work.
2.3
Risks incurred by failure to comply with the safety
precautions
Failure to comply with the safety precautions could result in
personal injury or damage to the pump or installation. Failure
to comply with the safety precautions could also invalidate any
claim for damages.
In particular, failure to comply may lead to problems such as:
– Failure of important pump or installation functions,
– Personal injury due to electrical, mechanical or bacteriologi-
cal causes.
2.4
Safety precautions for the operator
Existing regulations for the prevention of accidents must be
followed.
All risks caused by electrical energy must be eliminated. Direc-
tives conforming to the local or general regulations [such as
IEC, VDE etc.] 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 person-
nel who have studied the operating instructions closely.
Work on a pump or installation should only be carried out once
the latter has been brought to a standstill.
2.6
Unauthorised 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 consequen-
ces.
2.7
Unauthorised operating methods
The operating safety of the pump delivered is only guaranteed
for proper usage as detailed in section 1 of the operating
instructions. All values must neither exceed nor fall below the
limit values given in the catalogue or data sheet.
3 Transport and interim storage
The pump may only be transported in the woo-

den packaging provided. The pump must be
protected against moisture, frost and physical
damage.

4.1
Pump description
The VC pumps are vertical, single-stage circulating pumps with
a half-open multi-channel impeller and pressure pipe connec-
tions running parallel to the pump shaft. The pump and motor
are connected via a rigid stay pipe. An inlet filter is built into the
pump foot. The motor is held in place using lubricated, low-
maintenance antifriction bearings; the pump shaft is held in
place using friction bearings lubricated using the pumping
