Exhaust silencer
5.5 Operation
The exhaust silencer is a passive device and therefore no operating procedures are required. Follow the points below
to ensure you operate your exhaust silencer safely:
Ensure the exhaust silencer is correctly fitted before you use your GXS dry pump.
Do not touch the exhaust silencer when it is hot.
Avoid contact between the exhaust silencer and combustible materials, plastics or electrical cables.
Check the efficiency of your exhaust silencer regularly. A decrease in pump performance could indicate that
the exhaust silencer is becoming blocked with deposits or condensate from your pump exhaust. Remove the
silencer and drain it, or clean it as described in Section 5.6.
Check the inlet and outlet connections weekly to ensure that they are secure.
5.6 Maintenance
5.6.1 Safety information
Isolate the dry pumping system and other components in the process system from the electrical supply so
that they cannot be operated accidentally.
Allow the exhaust silencer to cool to a safe temperature before starting any maintenance. Do not touch the
exhaust silencer when it is hot.
Take suitable precautions when you maintain the exhaust silencer especially if it has been contaminated with
dangerous process materials.
Replace the exhaust silencer if it becomes damaged or blocked.
Obey the safety instruction given below and take note of appropriate precautions. If you do not
you can cause injury to people and damage equipment.
Personal protective equipment should be checked and used as specified by its supplier. If the
exhaust silencer has been exposed to hazardous chemicals, the use of suitable protective gloves
and clothing along with a respirator is recommended if contact with substances is anticipated.
