Check whether the pressure difference between suction and delivery side corresponds with the specifications of the pump s duty point Amechanical seal may never show visible leakage Noise The noise production of a pump depends to a great extent on the operating conditions The values stated in paragraph 10 9 Noise data are based on normal operation of the pump driven by an electric motor In case the pump is driven by a combustion engine or in case it is used outside the normal operation area as well as in case of cavitation the noise level may exceed 85 dB A In that case precautions should be taken like building a noise barrier around the unit or wearing hearing protection 20 Commissioning CFB EN 1212 2 3 CombiFlexBloc pt 5 1 5 2 5 2 1 5 3 5 4 Maintenance Regular maintenance Regularly check the outlet pressure No water should get into the terminal box of the electric motor when the pump room is sprayed clean Never spray water on hot pump parts The sudden cooling down may cause them to burst and hot water may flow out Flawed maintenance will result in shorter lifespan possible break down and in any event loss of warranty Shaft sealing Stuffing box packing Do not tighten the nuts 1810 any more after the running in period and adjustment If in time the stuffing box packing starts to leak excessively new packing rings have to be mounted instead of further tightening the nuts

Mechanical seal A mechanical seal generally requires no maintenance however it should never be allowed to run dry If there are no problems do not dismantle the mechanical seal As the seal faces have run in on one another dismantling usually implicates replacement of the mechanical seal If a mechanical seal shows any leakage it has to be replaced Lubrication of the bearings For maintenance of the motor bearings we refer to the instructions of the motor supplier concerned Environmental influences Regularly clean the filter in the suction pipe or the suction strainer at the bottom of the suction pipe as the inlet pressure may become too low if the filter or the suction strainer is fouled If there is a risk that the pumped liquid expands during solidification or freezing the pump has to be drained and if necessary flushed after it has been put out of service f the pump is out of service for a long time it has to be preserved Check motor for accumulation of dust or dirt which might influence motor temperature CFB EN 1212 2 3 Maintenance 21 eX 5 5 Noise If a pump starts making noise this may point to certain problems with the pump unit A crackling noise can indicate cavitation or excessive motor noise can indicate deterioration of the bearings 5 6 Motor Check motor specifications for start stop frequency 5 7 Faults A The pump of which you want to determine the fault may be hot or under
