In case that the diaphragm is broken the pump chamber should be replaced. Then it is also
recommended to check the ball bearings. For corrosion reasons or a clearly audible operating noise
the parts of the bearing service kit should be also replaced. (PSKITWLC155).
Please follow the general guidelines and safety advices when
handling with chemicals.
Disconnect mains supply before opening the pump housing!
Basically, operations at the pump must be performed during standstill only. The motor
has to disconnect from the power supply, e.g. by pulling out the power plug or using a
repair switch, and has to secure against unintentional switch-on. This can be realized by
a lockable emergency switch. To prevent an accidental re-starting a danger sign should
be installed..
After purging the pump with air there might be a small residual
amount of fluid inside the pump chamber.
Flush the pump chamber thoroughly and check the rinse fluid.
The dismounting and mounting of the pump should be done on a
rigid table or work bench. Please note: the pump is heavy.
All further warning and safety instruction of chapter 3 has to be
respected.
