Electrical stray current in the event of a short circuit
Electrical stray current in the event of a lightning strike
Static electricity
Electromagnetic waves (also lasers), ionising radiation
and ultrasound have an impact on the pump
Adiabatic compression and shock waves
Exothermic reaction, including the self-combustion of dust
Deposits of dust
Trained user
A trained user is a person who fulfils the requirements demanded of an
instructed person and who has also received additional training specific to
the system from ProMinent or another authorised distribution partner.
Service
The Service department refers to service technicians, who have received
proven training and have been authorised by ProMinent to work on the
system.
Protective measures to be observed by the customer
Limitation of the maximum temperature of the feed chem‐
ical
Limitation of the minimum ambient temperature
The customer must monitor and maintain the pump in
accordance with the "Maintenance" chapter.
The customer must fit a relief valve on the discharge side.
The customer must monitor and maintain the pump in
accordance with the "Maintenance" chapter.
The customer must monitor the capacity.
The customer must earth the pump and maintain the
earthing of the individual components.
The customer must put in place suitable protective meas‐
ures outdoors.
The customer must earth the earthing points and maintain
the potential equalisation cables of the individual compo‐
nents.
The customer must pay attention to potential equalisation
when dismantling.
Paint should not be applied too thickly.
Only clean plastic parts with a damp cloth.
Provide a temperature monitor on the dosing head with
feed chemical with critical friction properties.
The customer must wire the diaphragm rupture indicator in
such a way that it immediately stops the pump.
The customer must put in place measures in accordance
with EN 1127-1, if need be.
Feed chemical with electrical conductivity of < 50 pS/m,
which could form a combustible mixture: Do not allow the
unit to run dry – even when filling and emptying the liquid
end.
The pump is not suitable for use with substances that
have a tendency towards exothermic reactions or self-
combustion. Put in place measures in accordance with EN
1127-1, if need be.
Regularly clean the outside of the pump with a damp
cloth.
