1.4. ATEX declaration of conformity 

1.4.1.  Product description 

The 

precautions to be taken using the pumps in areas where the ATEX rules for “Ex II 2G Ex h IIb 

T4 Gb X” marked equipment apply. Only pumps mounted with EX-marked nameplate from DESMI 

are approved for / allowed to be used in EX areas. 

The pumps have been examined according to EN80079-36:2016 and EN80079-37:2016. 

Constructional safety “c” and an Ignition Hazard Assessment has been made. As a result of this 

assessment the following precautions are to be taken. 

1.4.2.  Precautions 

 

NOTE: Dry run is not allowed. Fill pump with liquid before start up. A cos 

 measuring device 

can be fitted to the power circuit and set to trip the drive power in case of the power 
consumption being too low. The liquid in the pump also serves as coolant for the shaft seal. Dry 
run will result in frictional heat being developed causing critical high temperatures at seal faces. 

 

NOTE: Pumping against closed outlet valve is not allowed for more than 2 minutes. A pressure 
switch can be fitted to trip the drive power in case of the outlet pressure being too high. 

 

NOTE: Choking or clogging of the pump can result in either too low load or overload of the 

motor or bending of the shaft. Use a strainer / filter in the suction pipe. A cos 

 measuring 

device can be fitted to the power circuit and set to trip the drive power in case of power 
consumption being too low or too high. The termistors (if any) in the electric motor can only be 
used to trip the drive power at overload. 

 

NOTE: User must replenish grease according to instruction manuals and replace bearings after 
90% of rated life i.e. 22500 hours. The bearing housing is fitted with a temperature sensor (or 
two in Spacer pumps) to be connected to the electrical control system on site. Set the system to 
trip the drive power 10°C above normal operating temperature.
