CAUTION!
Danger of injury to personnel and material damage
Disregarding the technical data during installation can
lead to personal injuries or damage to property.
– Observe the technical data - refer to the "Technical
data" chapter and, where applicable, the operating
instructions for the accessories.
WARNING!
ATEX pumps in areas at risk from explosion
– Metering pumps in areas at risk of explosion are
provided, as a matter of course, with an appropriate
safety relief valve on the outlet side of the metering
pump (which is used to protect against excessive
heating due to overloading and impact sparks
caused by the breakage of power end parts trig‐
gered by overloading.)
– Likewise a temperature monitor or a pressure side
flow control is to be fitting to metering pumps with
hydraulic diaphragm control for T4. (Protection
against impermissible heating up in the event of
continuous operation by the internal relief valve).
– Should the various components have differing tem‐
perature classes, scope for using the complete
pump depends on the component with the lowest
temperature class.
– Hydraulic diaphragm pumps are highly suitable,
although the design with Ex "i" diaphragm rupture
sensor and a pressure-side flow control is required.
– Ensure that installations in areas at risk of explosion
are checked by a "recognised competent" person.
– Please note the relevant national regulations during
installation!
WARNING!
Risk of fire with flammable feed chemicals
– Combustible media may only be transported using
stainless steel or Hastelloy C dosing heads.
– Metering pumps can be used for metering combus‐
tible media, however as a matter of principle only of
a design including ATEX diaphragm rupture sensors
and a pressure-side flow control.
– During filling and draining of the liquid end, an
expert must ensure that feed chemical does not
come into contact with air.
– If necessary, the operator must implement further
measures.
