Service and Maintenance 7
Rotating parts! Risk of trapping and crushing!
Possible dangerous situation: Severe or fatal injuries!
Do not work on rotating pump!
7.1 Service after Start-up
Following approximately 50 hours of operation, you should check all bolt connections on the pump or
pump unit, excepting only the packing box seal; retighten, if necessary.
7.2 Inspection and Service Notes
Actual wear is significantly
influenced by different media
and pressure requirements.
Calculate the necessary
inspection/service intervals on a
plant-specific basis.
check for leakage, if it leaks
all the time, replace
lubricate / replace bearing
7.3 Lubrication
There is no fixed lubrication intervals defined for this pump.
Their bearing points are equipped with maintenance-free roller bearings, which have all been
permanent lubricated. It is recommended to replace these bearings after 20.000 hours of operation
or at the latest after 5 years, whichever occurs first. (Pumps in an explosion area 10.000 hours of
operation or at the latest 3 years)
up to range KL 80 the roller bearings are provide in the factory with grease. Replacement of roller
bearings: Fill the cavities between the rolling elements full with grease.
In general, fill the space between the bearings with grease. This lubrication is to reduce friction and
better heat dissipation from the shaft seals.
The lubricant quantities required for this purpose will be as listed in the table 3.
In the interests of a long service life of your pump you should introduce shortened replacement
intervals in particularly difficult operating conditions such as
high relative humidity,
an aggressive environment,
major temperature variations, etc.
Lubricate all drive unit bearings in accordance to the instructions provided by the manufacturer.
