In normal use, the lifetime of the diaphragms and valves
is typically 15,000 operating hours. Bearings have a typi-
cal durability of 40000 h. Motor capacitors have a typi-
cal durability in the range of 10000 to 40000 h depending
strongly on operation conditions including ambient tem-
perature, humidity or load.
➨
Ensure that the pump cannot be operated acciden-
tally. Never operate the pump if covers or other
parts of the pump are disassembled.
➨
Switch off the pump. Disconnect the electrical
power cord and wait five seconds
before starting
maintenance to allow the capacitors to discharge.
➨
Note
: The pump may be contaminated with process
chemicals, which have been pumped during operation.
Ensure that the pump is completely decontaminated
before maintenance commences.
+
Take adequate precautions to protect people from the
effects of dangerous substances if contamination has
occurred. Use appropriate protective clothing, safety
goggles and protective gloves.
+
Wear parts have to be replaced regularly.
+
Never operate a defective or damaged pump.
+
Check every motor capacitor regularly by measuring
its capacity and estimating its time in operation. Re-
place old capacitors early enough to prevent a failure
in operation. If an old motor capacitor fails, the capaci-
tor may get hot. It may even melt or emit a flame, which
could be
dangerous for persons and equipment in
the vicinity
. The capacitors have to be replaced by an
electrician.
