Requirements for safe access

For slurry pump lubrication the following factors are generally assessed in order to develop the lubrication solution:

Pump manufacturer’s recommendations

Seal types

Characteristics of recommended lubricant

Typical bearing operating temperatures

Operating conditions

Lubrication challenges associated with pump maintenance include:

Liquid and slurry contamination require frequent or continuous grease purging

to prevent ingress into the pump mechanical assembly

High speed / high mechanical working of the grease on large pumps require

more frequent and controlled grease replenishment /exchange

Insufficient grease exchange intervals may result in lubrication deterioration or

more extreme ‘starvation’ conditions

Large or excess grease addition volumes results in grease ‘churning’ and

overheating

Hazardous working conditions (rotating equipment pinch points, falling into

open drains or sumps, or exposure to hazardous chemicals)

Maintenance challenges which restrict or limit effective relubrication may result in:

Contamination of bearings (from inadequate seal purging) causing rapid

deterioration of lubrication conditions

Inadequate / excessive lubrication causing deteriorating lubrication conditions,

accelerated grease aging, oxidation and wear rates

Accelerated wear rates (caused by contaminants or indadequate / excessive

grease replenishment) and finally premature bearing failure
