The lubricating grease could become contaminated!
Clean the grease lubricating nipples before using them for re-lubrication.
. After approx. 5,000 operating hours
. At least once a year
. Required grease quantity ( Section 7.2.3.2.3 Page 46)
. After 16,000 operating hours
. At least every 2 years
. Required grease quantity ( Section 7.2.3.2.3 Page 46)
Under unfavourable operating conditions (e.g. high room temperature, high atmospheric
humidity, dust laden air, aggressive industrial atmosphere) check the bearings earlier and
clean and re-lubricate them, if required.
The pump has been dismantled for changing the grease. ( Section 7.4 Page 47)
1. Only half-fill the bearing cavities with grease.
