Has Your Lubrication System Kept Pace With Your Plant ?

Your production has increased. Loads have changed. Machines are running harder. But is your lubrication system still
operating on yesterday’s design?

A STEEL PLANT rarely operates today exactly as it did when it was commissioned.
Over the years, production targets increase, machines run for longer hours, loads change, new
lubrication points are added and operating conditions become more demanding.
We upgrade drives, automation and process controls to meet these changing requirements.
But how often do we ask:

Has the lubrication system also been reviewed for today’s operating conditions?

A pump running at every programmed interval does not necessarily mean every bearing is
receiving the lubrication it requires.

Yesterday’s Design. Today’s Demand.

Every centralized lubrication system is designed Now consider a rolling mill whose production has increased
around specific operating parameters: significantly over the years. The equipment may be operating at
higher loads, higher speeds or for longer durations Bearings and other
• Number of lubrication points moving components are working harder—but the lubrication quantity
• Lubricant quantity and frequency and frequency may still be based on the original design.
• Pipe diameter and length
• Lubricant characteristics This creates a possible mismatch between today’s machine
• System pressure demand and yesterday’s lubrication design.
• Pump capacity
• Equipment speed, load and operating conditions
