WARNING!
Warning of hazardous feed chemical
Should a dangerous feed chemical be used: it may
escape from the hydraulic components when
working on the pump, material failure or incorrect
handling of the pump.
– Take appropriate protective measures before
working on the pump (e.g. safety glasses,
safety gloves, ...). Adhere to the material safety
data sheet for the feed chemical.
– Drain and flush the liquid end before working
on the pump.
WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious inju‐
ries.
Please ensure when handling hazardous sub‐
stances that you have read the latest safety data
sheets provided by the manufacture of the haz‐
ardous substance. The actions required are
described in the safety data sheet. Check the
safety data sheet regularly and replace, if neces‐
sary, as the hazard potential of a substance can be
re-evaluated at any time based on new findings.
The system operator is responsible for ensuring
that these safety data sheets are available and that
they are kept up to date, as well as for producing
an associated hazard assessment for the worksta‐
tions affected.
WARNING!
Only with flammable feed chemicals Danger of
explosion with isolating feed chemicals
A flammable feed chemical with a low electrical
conductivity (< 50 pS/m) can form explosive
vapours with air in the liquid end and statically
charge the diaphragm.
– It is essential that you avoid the liquid end run‐
ning dry.
