1 General 

This KSB ITUR pump has been developed in 
line with state-of-the-art technology, 

manufactured with great care and put through continuous 
Quality Control. The present Instructions Manual will provide 
you with knowledge of the pump and the ways it can be 
applied. 

It contains important instructions to operate the pump 
appropriately and profitably. It is important to comply with the 
manual in order to guarantee reliability and a long useful life 
for the pump, whilst avoiding any possible risks. 

This manual does not include any local regulations or any 
instructions with regards to assembly personnel, which the 
user shall be responsible for. 

This group cannot be used in conditions in excess of 
those established in the technical documentation 
with regards to the liquid to be pumped, flow, speed 

(rpm), density, pressure and temperature, and with regards to 
the motor power or anything else set out in the instructions 
manual and contractual documentation. Check with the 
manufacturer as appropriate.  
The factory plate shows the model/size, the main service data 
and the manufacture number of the pump. Please include 
these data in any queries, subsequent orders or requests for 
spare parts. 
If you require any additional information or have problems with 
regards to failures, please contact the nearest KSB ITUR 
service. 

2 Safety 

This instructions manual contains fundamental instructions 
which must be complied with in assembly, service and 
maintenance. It must be read by assembly personnel, 
competent technical personnel and users before installing and 
starting up, and it must be available at all times at the place of 
location of the machine. 
Proceed not only in line with this main safety chapter, but also 
observing the instructions described in other similarly 
important safety points. 

2.1 

Marking of warnings in this manual 

The instructions which may involve hazard if not observed are 
highlighted with the following general symbols: 

Safety instructions which may involve a hazard to 
people and facilities if not complied with in 
accordance with ISO 7000-0434. 

Safety instructions to prevent electrical hazards in 
accordance with IEC 417-5036. 

Safety instructions which may affect the 
equipment and its operation if not complied 

with. 

 Safety instructions to prevent the risk of explosion. 
Only applicable to groups with ATEX plate, specially 

designed to satisfy Directive 94/9/EC on the prevention of the 
risk of explosion. 

The details shown directly on the machine, such as: 

-  Rotation direction arrow 
-  Fluid connection identifications 

These must be observed, and conserved in a manner which 
ensures they are legible. 

2.2 

Personnel qualifications and instruction 

All Service, Maintenance, Inspection and Assembly personnel 
must be duly qualified. The terms regarding responsibility, 
competence and supervision of personnel must be regulated 
by the user in an exact manner. 

Note 

Any personnel lacking appropriate know-how must be duly 
instructed. This preparation can be obtained upon request by 
the machine user to the manufacturer or supplier of the 
machine. 
Finally, the user must ensure that all personnel have fully 
understood the content of the instructions manual. 

2.3  Risks of failing to comply with the safety 
instructions  

Failure to comply with the safety instructions may lead to risks 
both for people, the environment and the machine, and may 
lead to the loss of any entitlement to claims. 
In particular, failure to comply may cause the following 
hazards: 

-  Failure of important machine/facility functions. 
-  Failure of the prescribed maintenance and conservation 

methods. 

-  Personal hazard resulting from electrical, mechanical or 

chemical effects. 

-  Danger to the environment due to escaping noxious 

products. 

2.4 

Conscientious safety at work 

The safety instructions contained in this Manual must be 
observed, as must international prescriptions on Health and 
Safety at Work and any possible Safety Regulations at the 
workplace of the user. 

2.5  Safety instructions for users and service 
personnel 

The operator is responsible for keeping the 
temperature of the fluid within the pump classification 

temperature limits. 

-  The installer must ensure that the parts of the machine 

which may create danger due to heat or cold are 
protected against accidental contact. The operator shall 
check as well that the coupling guard is in place and 
firmly secured. 

-  The contact protections of moving parts (e.g. couplings) 

must not be removed whilst the machine is in service. 

-  Provide the personnel with protective equipment and 

make sure it is used. 

-  Any possible leaks (e.g. through the shaft sealing) of 

hazardous products must be channelled in such a 
manner as they do not present any risk to people or the 
environment, in line with corresponding legislation. 

Note 

-  Follow safety instructions due to use of power. In this 

respect refer to the applicable national safety regulations 
and/or regulations issued by the energy supply comp 

2.6 Safety instructions for maintenance, 
inspection and assembly work 

The user must ensure that all maintenance, inspection and 
assembly tasks are carried out by authorised, qualified, 
specialised personnel who have been sufficiently informed 
through careful study of the instructions manual.
