GENERAL COMMENTS
A routine maintenance program can extend the life of your pump. Well maintained equipment
will last longer and require fewer repairs. You should keep maintenance records as this will help
pinpoint potential causes of problems.
!
The Preventive Maintenance section must be adhered to in order to keep the applicable ATEX classification of the
equipment. Failure to follow these procedures will void the ATEX classification for the equipment.
