K9 Ensure the correct design and material choice of the
protective cover.
No dangerous dust accumulation may take place. A
design open at the bottom is preferred: although more
dust can blow in from below the dust can also more
easily be removed. Better cooling for the coupling.
• The protective cover must fit widely around the
coupling in case of dents, and to make no contact with
any dust layer on the inside of the protective cover.
• For cat. 2: no more than 7.5% magnesium (see EN
13463-1, 8.2)
K10
K11
Ensure a correct number of revolutions.
Choose the correct electric motor (only with units)
Correct capacity and number of revolutions, etc. The
motor may not be too oversized. The motor must cut
out when the pump requests more power as a result of a
broken bearing, rotor malfunction, etc. EX-motor, cat. 2
K12 Choose the correct bearing (according to EN 13463-
5:2003, 6.1):
Take account of the intended working life of the
bearing.
• Protect against dust with retaining ring.
• Ensure earthing for the circulating flows.
• With oil-lubricated bearings: ensure the correct oil
viscosity in relation to the outside temperature (and
medium temperature).
Transport
T1 Make sure that the pump is mechanically well
shielded during transport.
Assembly
M1 Make sure that rotor nut is tightened at the correct
Nm.
M2 Make sure that setting between rotor, wear plate and
intermediate housing is correct.
M3 Make sure that packing is enclosed in the correct way.
M4 Make sure that nuts and bolts are assembled at the
correct Nm.
M5 Use new packing when servicing
M6 Check the resistance list to ensure that assembled
elastomers are suitable for the pumped medium.
Also applies for mechanical shaft seal
• Also applies for auxiliary system
• Also applies for packing
M7 Assemble the pump parts according to instructions.
M8 Ensure the good assembly of the mechanical shaft
seal as indicated by the supplier.
M9 Ensure the good assembly of the auxiliary system as
indicated by the supplier.
