1.7 Unauthorized Modifications and
Manufacture of Spares
Modifications or changes to machines / equip-
ment are only permissible with the manu-
facturer's agreement. Original spare parts
and accessories authorized by the manufac-
turer ensure safety.
The use of other components revokes any lia-
bility for consequences which may result.
1.8 Improper Application
Delivered machinery / equipment is only gua-
ranteed safe for the use specified.
This machine / equipment was designed in
accordance with the prescribed conditions of
use.
The limits of use are laid down in the con-
ditions of use and should in no way be ex-
ceeded.
1.9 Specific Points for the Use of a
NEMO
®
Pump
A NEMO
®
pump must be used for the
purpose only for which it was sold.
If you change or wish to change the process
medium, you must check with either the
supplier or manufacturer that the pump is
suitable for the new medium. This is espe-
cially important with aggressive, poisonous or
otherwise hazardous substances.
Pump criteria include:
1. Compatibility with the medium
2. Suitability for seal design / material,
especially the shaft seal
3. Resistance to pressure and temperature
of the medium.
Please note that NEMO
®
pumps are pro-
gressing cavity pumps and as such can gene-
rate very high pressure.
A blockage or the chance closure of a valve
in the discharge line can cause a pressure rise
manifold as high as can be tolerated by the
installation. This can result in the bursting of
pipes, which must be avoided especially in
the case of dangerous media.
Corresponding safety equipment must
therefore be installed, for example an
emergency stop button, a pressure relief
valve with return pipe or a bursting disc.
During maintenance and repair work on the
pump please note the following:
1. Ensure that the pump drive can not
be turned on without authorization.
2. When opening the pump follow
the instructions for handling the
medium (eg. protective clothing,
no smoking etc).
3. Before putting the pump back into
operation ensure that all guards and
other safety devices (eg. drive–belt
protection, coupling protection) are
properly re–installed.
