Starting the pump
Before starting up, those responsible must be duly informed about the pump and
the safety instructions. This Annex, along with the instructions manual, will be
available to staff at all times.
In order to carry out any type of work in potentially explosive atmospheres, it is
necessary to adopt special safety measures such as permits to work.
5.1.
START-UP
An explosive atmosphere may be formed during the start-up of the pump.
Therefore, permits to work will be required and these tasks must only be carried
out by qualified or trained personnel, as specified by EU Directive ATEX
2014/34/EU.
5.1.1.
Checks before starting the pump
Before starting up the pump, make sure that the suction and discharge valves of
the pump are open.
If there is a risk that the pump is operated in vacuum (i.e. with no fluid), it is recommended that a flow-
detection sensor is fitted in the suction side of the pump, or any other device preventing the pump from
operating in dry conditions.
In the case of the (non-cooled) single seal option, the pump and the area around the seal must be covered
by the pump fluid before start up.
If the fluids that have to be drained are inflammable, the possible formation of
potentially explosive atmospheres must be considered; permits to work should
therefore be issued.
