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. 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.
MAINTENANCE SCHEDULE
INSPECTION INTERVALS
Inspection intervals should be shortened appropriately if
the pumpage is abrasive and/or corrosive,
!
or if the environment is classified as potentially
explosive.

•
Bearing lubrication
•
Seal Monitoring
•
Vibration Analysis
•
Discharge Pressure Monitoring

ROUTINE INSPECTIONS
•
Check the level and the condition of the oil
•
Check for unusual noise, vibration, and bearing
temperatures
•
Inspect the pump and piping for leaks
•
Check the seal chamber/stuffing box leakage
