WARNING
Danger of injury and intoxication when handling hazardous liquids!
►Always wear protective equipment when working on the pump.
►Pump tube must be completely emptied.
8.1 Lubrication
No parts of the Lutz eccentric screw pump need to be lubricated at short intervals. For assembly works and
lubricant addition of the lip seals in the bearing unit a foodstuff compatible lubricant must be used. We recommend
type PARALIQ GTE 703.
The flanged-on drive units should be serviced as follows:

The rolling bearings of the motor and the pump tube should be replaced after 8000 hours or 2 years of operation.
Exchange the lip seals of the bearing unit as well. Note the recommendation for lubricant in the spare-parts list
of the manufacturer.
The zone of the pump coming into contact with the liquid is free of lubricants.

9. Repairs
The pump must be switched off and repaired immediately if liquid leaks out below the pump motor (→ Fig. 26).
► Repairs should only be made by the manufacturer or authorized Lutz dealers.
► Only use original Lutz Pumpen spare parts. If other spare parts are used, liability on the part of Lutz Pumpen
is obsolete.
► The setting values of the mechanical seal must be observed without fail. Otherwise inadmissible warming up
will occur.
