Installation, Operating and Maintenance Instruction
The permitted application conditions and design
details of the delivered pump are shown in the
attached data sheet and / or order confirmation.
3.2 Bearings
TDB design: Drive-side in the rolling bearings of the
motor. The bearings have lifetime grease lubrication
so that no maintenance is required.
TDV design: Drive-side: Pressure-side angular ball
bearing (fixed bearing) with relubrication mechanism
(lubrication nipple)
