5 Maintenance
5.1 Daily maintenance
• Regularly check the oil level, see figure 7.
ƽ 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!
5.2 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. If a
mechanical seal shows any leakage it has to be replaced.
5.3 Lubrication of the bearings
• During operation the constant level oiler should never be empty. Take care to top up
timely.
• Frequency of oil change is dependent on pump service and environmental conditions.
As a general guide, oil in the bearing bracket should be changed every 4000
operating hours or at least every 6 month, after the initial change. For recommended
oils and quantities see paragraph 10.3 "Lubricants".
! Make sure the used oil is discharged safely.
See to it that it does not get into the environment.
