Installation, hydraulic

Disregarding the technical data during installation can lead to personal
injury or damage to property.
Observe the technical data - refer to the Chapter "Technical data" and,
n
where applicable, the operating instructions for the accessories.
WARNING!
ATEX pumps in areas at risk from explosion
– Metering pumps must have an appropriate safety
relief valve on the discharge side in order to protect
against excessive heating due to overloading or
impact sparks caused by the breakage of power end
parts.
Flammable feed chemicals
Pumps with the identity code option "Multi-layer safety diaphragm with
n
rupture signalling (contact)" are only approved for use with flammable
feed chemicals with electrically conductive dosing heads, at back
pressures of over 2 bar and only if the operator takes appropriate
safety measures.
Rupture signalling or, possibly, a flow control fitted on the discharge
n
side must stop the pump safely and as quickly as possible as soon as
there is a diaphragm rupture or, for instance, in the event that there is
no flow.
Do not allow it to run dry.
n
It is the responsibility of the operator to implement further measures if
n
necessary.
WARNING!
Warning of feed chemical reactions to water
Feed chemicals that should not come into contact with
water may react to residual water in the liquid end that
may originate from works testing.
– Blow the liquid end dry with compressed air through
the suction connector.
– Then flush the liquid end with a suitable medium
through the suction connector.
WARNING!
The following measures are an advantage when working
with highly aggressive or hazardous feed chemicals:
– Install a bleed valve with recirculation in the storage
tank.
– Install an additional shut-off valve on the discharge
or suction ends.
PTFE seals
PTFE seals, which have already been used / compressed, can no
n
longer reliably seal a hydraulic connection.
Always use new and unused PTFE seals.
n
Possible suction problems
The valves may no longer close properly with feed chemicals with par‐
n
ticles larger than 0.3 mm.
Install an appropriate filter in the suction line.
