6 Commissioning
Before commissioning, the pump/pump station should be checked and a functional test carried out. Particular
attention should be paid to the following:
g
In explosive zones care must be taken that during switching on and operation of the pumps the pump
section is filled with water (dry running) or alternatively is submerged or under water (wet installation).
Ensure in this case that the minimum submergence given in the data sheet is observed, Other types
of operation e.g. snore operation or dry running are not allowed.
•
Have the electrical connections been carried out in accordance with regulations?
•
Have the thermal sensors been connected?
•
Is the seal monitoring device (where fitted) correctly installed?
•
Is the motor overload switch correctly set?
•
Have the power and control circuit cables been correctly fitted?
•
Was the sump cleaned out?
•
Have the inflow and outflows of the pump station been cleaned and checked?
•
Is the direction of rotation of the pump correct - even if run via an emergency generator?
•
Are the level controls functioning correctly?
•
Are the required gate valves (where fitted) open?
XFP
•
Do the non-return valves (where fitted) function easily?
•
Have the hydraulics been vented in the case of dry-installed pumps?
AFLX/VUPX
•
Has the steel riser pipe, or concrete sump be cleaned thoroughly (builder’s rubble, etc.)?
•
Are any paint remnants removed from the conical surfaces on the pumps or on the coupling ring? Are these
conical surfaces to be greased?
