11. INSPECTION AND MAINTENANCE
Inspect the shaft seal for leaks at regular intervals.
Activate the relief valve at regular intervals in order to check the function. If the valve is
choked, replace or clean it, if possible.
-
Before inspection of a pump without guard check that the pump cannot be started
unintentionally.
-
The system is to be without pressure and drained of liquid.
-
The repairman must be familiar with the type of liquid which has been pumped as
well as the safety measures he is to take when handling the liquid.
11.1 DRAINING THE PUMP
When the piping system has been drained, note that there is still liquid in the pump. Remove
the liquid by dismantling the pipe plug (3) in the inlet cover of the pump.
11.2 BEARING
The pump is equipped with a ball bearing which is dimensioned for a nominal life of 25,000
working hours. The bearing is lubricated for life and requires no attention but is to be replaced
in case of noise or bearing wear.
