LIFTING DEVICES
Mounted on individual parts are intended for lifting 
the individual part only. Lifting slings must not put 
excessive side thrust on the lifting device. 
GUARDS MUST NOT BE REMOVED WHILE
THE PUMP IS OPERATIONAL
LIFTING ROTOR
Lifting rotor must be setting before start up the 
pump, according nameplate. See point 5.5 
FLUORO-ELASTOMERS (When fitted.)
When a pump has experienced temperatures over 
250 ºC (482 ºF), partial decomposition of fluoro-
elastomers (eg Viton) will occur. In this condition 
these are extremely dangerous and skin contact 
must be avoided. 
HANDLING COMPONENTS
Many precision parts have sharp corners and the 
wearing 
of
appropriate
safety
gloves
and
equipment is required when handling these 
components. To lift heavy pieces above 25 kg (55 
lb) use a crane appropriate for the mass and in 
accordance with current local regulations. 
 
1.6.4 Products used in potentially explosive 
atmospheres 
Measures are required to:
•
Avoid excess temperature
•
Prevent build up of explosive mixtures
•
Prevent the generation of sparks
•
Prevent leakages
•
Maintain the pump to avoid hazard
 
The following instructions for pumps and pump 
units when installed in potentially explosive 
atmospheres must be followed to help ensure 
explosion protection. Both electrical and non-
electrical equipment must meet the requirements of 
European Directive 94/9/EC. 
 
1.6.4.1 Scope of compliance 
Use equipment only in the zone for which it is
appropriate. Always check that the driver, drive 
coupling assembly, seal and pump equipment are 
suitably rated and/or certified for the classification of 
the specific atmosphere in which they are to be 
installed. 
 
Where Flowserve has supplied only the bare shaft 
pump, the Ex rating applies only to the pump. The 
party responsible for assembling the pump set shall 
select the coupling, driver and any additional 
equipment, with the necessary CE Certificate/ 
Declaration of Conformity establishing it is suitable 
for the area in which it is to be installed. 
 
1.6.4.6 Preventing leakage 
The pump must only be used to handle
liquids for which it has been approved to have the 
correct corrosion resistance. 
 
 
1.7 Nameplate and warning labels
 
1.7.1 Nameplate 
Every pump has a name plate made in stainless 
steel with information regarding operating condition 
as capacity, total dynamic head, rotational speed, 
specific gravity, rotor setting, power consumption 
and serial number. 
 
1.7.2 Warning labels 
A stainless steel plate is attached to discharge 
head requesting removing coupling bolts before 
checking motor rotation and avoid damage to the 
equipment. 
 
 
 
 
1.8 Specific machine performance
For performance parameters see data sheet and 
performance curve in this User Instructions. 
 
1.9 Noise level
When pump noise level exceeds 85 dBA attention 
must be given to prevailing Health and Safety 
Legislation, to limit the exposure of plant operating 
personnel to the noise. The usual approach is to 
control exposure time to the noise. 
 
Pump noise level is dependent on a number of 
factors - the type of motor fitted, the operating 
capacity, 
pipework
design
and
acoustic
characteristics of the building.
