Maintenance

5.1

Safety and maintenance frequency



Ensure that the maintenance technician is familiar with the safety procedures which relate to the products
pumped.



Allow the pumps to cool to a safe temperature before fitting lifting eye bolts or starting maintenance work.



Vent and purge the dry pumping system with nitrogen before starting any maintenance work.



Isolate the dry pumping system and other components in the process system from the electrical supply so
that they cannot be operated accidentally. Note that the emergency stop switch on the dry pumping system
is not an electrical isolator, unless a disconnect box accessory is installed.

WARNING

Only personnel specially trained to perform electrical maintenance should attempt
troubleshooting inside electrical enclosures. These enclosures contain hazardous voltages and are
not operator areas.

WARNING

Leak test the system after maintenance and seal any leaks found to prevent leakage of dangerous
substances out of the system and leakage of air into the system.

WARNING

Obey the safety instructions in this Section and take note of appropriate precautions. Failure to
observe these instructions may result in injury to people and damage to equipment.

WARNING

Electrical, nitrogen and water supplies are all potentially hazardous energy sources. Before
carrying out any maintenance, the supply of these sources should be locked and tagged out.

WARNING

Do not touch the pump exhaust and check valve (if fitted) whilst the pump is running since the
temperatures of these parts can cause burns. These parts will remain hot after the pump has
stopped.

WARNING

Personal protective equipment should be checked and used as specified by its supplier. Hazardous
chemicals that have been pumped are located within the pumps and piping. Use of suitable
protective gloves and clothing along with a respirator is recommended if contact with substances
is anticipated. Particular caution should be exercised when working with fluorinated materials
which may have been exposed to temperatures greater than 260 °C. Refer to Edwards Material
Safety Data Sheets for detailed information.
