Maximum pump sound pressure level 91 dB
Depending on the operating conditions, the maximum
sound pressure level of the device can reach 88 dB ±
3 dB. Bear this in mind and take suitable measures to
reduce any impact caused by this sound pressure
level. The type and implementation of suitable meas‐
ures depends on the local circumstances and is the
responsibility of the system operator.
Check the fastening elements are correctly seated.
Before commissioning the double diaphragm pump,
you must check that all fastening elements with sealing
rings are correctly seated. The seals may 'creep' , so
that the fastening elements come loose over time.
In the event of a diaphragm rupture
In the event of a diaphragm rupture, the pumped
medium can enter the air system of the double dia‐
phragm pump and from there into the atmosphere. If
the pumped medium is a dangerous, harmful or toxic
substance, the air outlet must be routed to a suitable
area where safe disposal is possible.
