11.10 Specific parts
11.10.1 Bolts and nuts
Damaged bolts and nuts or parts with damaged screw thread must be removed or replaced as soon as
possible with fixing material of the same fixing class.
When tightening, preferably use a torque wrench, see technical specifications B-Series.
Extra point(s) for attention with ATEX pumps.
M4.
Make sure that nuts and bolts are assembled at the correct Nm.
11.10.2 Flat seals and tape
Never apply already used seals or tape.
Replace the flat seals and filled seals under the stoppers with original BBA Pompen BV seals.
Extra point(s) for attention with ATEX pumps.
M3.
M5.
M6.
Make sure that packing is enclosed in the correct way.
Use new packing when servicing.
• Take account of pressures in the pump.
• Take account of the interaction of packing with the medium to be pumped.
Check the resistance list to ensure that assembled elastomers are suitable for the
pumped medium.
11.10.3 Synthetic and rubber parts
Do not expose synthetic or rubber (cables, hoses, seals) parts to the effects of oils, solvents and cleaning
products or other chemicals unless they are specially suitable for this.
Extra point(s) for attention with ATEX pumps.
M6.
Check the resistance list to see if assembled elastomers are suitable for the
medium to be pumped.
11.10.4 Suction strainer filter
The filter(s) and suction strainer(s) present in the installation must be regularly cleaned. With a soiled
filter in the suction line the inlet pressure can become too low. A soiled filter in the pressure line causes
the pump pressure to increase.
Extra point(s) for attention with ATEX pumps.
K7.
K5.
P1.
Make sure that dirt particles in piping systems cannot cause blockages.
Ensure a good inflow opening in the suction line.
Do not expose the pump to higher pressures than which the pump is suitable
according to the curve.
