Explosion hazardous environments – ATEX
Static electricity may occur in the pump under operation, which may cause explosion
and injury. Special conductive pulsation dampeners DTX are available for such applications.
Follow below instructions and local/national rules for safe use.
ATEX (directive 94/9/EC) classification of Tapflo DTX dampeners:

2
– high level of protection (can be used in zone 1);
Atmosphere
G
– gas;
D
– dust;
Explosion group
IIB
– such as ethylene;
Type of protection
c
– constructional safety;
Temperature class
T4
– in the event of a malfunction, the maximum temperature of a surface that
may be exposed to gas T4 = 135 °C.
Earth connection of dampener and other equipment
Connect a suitable earth wire to the stainless steel earth connection that is placed on the inside
of one of the pump housings. Connect the other end of the earth wire to earth and also make sure
that other equipment like hoses/pipes/containers etc. are properly earthed/connected.
1.5.3.
Air pressure
The maximum air pressure for Tapflo dampeners is 14 bar. Higher air pressure than 14 bar can
damage the dampener and may cause injury to personnel in vicinity of the dampener.
Please make sure that supply air to the dampener must have the same flow and pressure as the
pump that dampener is installed with.
1.5.4.
Noise level
At tests, the noise level from a Tapflo dampener has not exceeded 70 dB(A).
1.5.5.
Temperature hazards
Raised temperature can cause damage to the dampener and/or piping and may also be hazar-
dous for personnel in the vicinity of the dampener/piping. Avoid quick temperature changes and
do not exceed the maximum temperature specified when the dampener was ordered.
