In the same way, as these Operating Instructions 
of the pump, all possibly attached Operating 
Instructions of accessories (e.g. motor) must be 
noticed and kept available. 

 

2.2 Dangers of non-observance of the 
Safety Instructions 

Non-observance of the Safety Instructions can 
lead to loss of any claim for damages. 

Further, non-observance can lead to following risks: 

 

Failure of important functions of the machine or 
facility. 

 

Failure of electronic appliances and measuring 
instruments by magnetic fields. 

 

Endangering of persons and their personal 
property by magnetic fields. 

 

Endangering of persons by electric, mechanic and 
chemical influences. 

 

Endangering of environment through leakage of 
dangerous substances. 

 

 

On application of the unit in areas endangered 
to explosion special attention must be paid to  
sections marked with Ex.

 

 

2.3 Safety Instructions for the Operator / 
Worker 

 

Depending on the operating conditions, wear and 
tear, corrosion or age will limit the working life of 
the pump/pump 

unit, and its specified 

characteristics. The operator must ensure that 
regular inspection and maintenance are carried 
out so that all parts are replaced in good time, 
which would otherwise endanger the safe 
operation of the system. If abnormal operation or 
any damage is observed, the pump must cease 
operation immediately. 

 

If the breakdown or failure of any system or unit 
could lead to people being hurt or property being 
damaged, such system or unit must be provided 
with alarm devices and/or spare modules, and 
they should be tested regularly to ensure that they 
function properly.

 

 

If there is any risk of injury from hot or cold 
machine parts, these parts must be protected 
against contact by the user, or suitable warning 
signs must be affixed. 

 

Contact protection on moving parts (e.g. coupling 
guards) must not be removed from systems that 
are in operation. 

 

If the sound level of a pump or pump unit is above 
85 dB(A) an ear protection has to be used when 
staying near the pump for some time. 

 

If dangerous media (e.g. explosive, toxic, hot) leak 
out (e.g. from shaft seals), these must be directed 
away so that there is no danger to people or the 
environment. The provisions of the law must be 
observed. 

 

Measures should be taken to exclude any danger 
from electricity (e.g. by complying with the local 
regulations on electrical equipment). If work is 
carried out on live electrical components, they 

should be unplugged from the mains or the main 
switch turned off and fuse unscrewed. A motor 
protection switch is to be provided. 

 

2.4 Safety Instructions for Maintenance, 
Inspections and Mounting Work 

 

The operator is responsible that any maintenance, 
inspections and mounting work is made by 
authorized competent personnel, which must be 
informed by having read the Operating 
Instructions. 

 

Basically, all work on the pump or pump unit 
should only be carried out when the pump is 
stationary and not under pressure. All parts must 
be allowed to return to ambient temperature. 
Make sure that no-one can start the motor during 
such work. It is essential that the procedure for 
stopping the system described in the Operating 
Instructions is observed. Pumps or pump systems 
that carry media that are dangerous to health must 
be decontaminated before being taken apart. 
Safety Data Sheets for the various liquids handled. 
Immediately after finishing work, all safety and 
protective devices must be replaced or restarted. 

 

2.5 Unauthorized Alteration and Spare 
Parts Production 

Alteration or changes of the machine are permitted 
after agreement with the manufacturer. 
Original spare parts and accessory authorized by the 
manufacturer are serving the safety. 
The use of other parts can lead to loss of liability for 
there from resulting consequences. 

 

2.6 Undue Operation

 

The operating safety of the delivered machine  can 
only be guaranteed by designated use acc. to the 
following chapters of the Operating Instructions. The 
limits stated in the data sheet and / or order 
confirmation must not be exceeded under any 
circumstances. 

 

2.7 Explosion Protection

 

On application of units in areas endangered to 
explosion measures and references in the chapters 
2.7.1 to 2.7.6 must be observed, so that explosion 
protection is guaranteed. 

 

2.7.1 Filling of unit 

 

 

During operation of the pump the system of the 
suction and pressure pipe  and the pump itself 
must permanently be filled with the pumped 
liquid. Thus, no explosive atmosphere can 
develop and the danger of dry-run is avoided.

 

 

 

If the operator can´t guarantee that, according 
monitoring measures must be provided.
