7.4.2 Bearing with oil lubrication
The pump is supplied empty (no oil). Before the
initial start up, pour oil into the oil inlet hole until
the oil level reaches the mark on the dipstick.
Oil drainage
Oil filling
Constant level oiler
As an additional accessory, it is possible to
connect a constant level oiler. In this case, the
bearing support must be filled with oil through the
oil inlet hole, until the oil is visible in the screw-in
elbow, the oil reservoir having been removed.
Subsequently the oil reservoir should be filled with
oil and put into its correct position.
The bearing housing will be supplied with oil from
the constant level oiler with the correct amount as
long as there is oil in the reservoir.

4. Never fill with oil here, always use the oil inlet
hole.
Oil change intervals
If the bearings are new, change the oil after about
200 hours and subsequently annually. These
intervals only apply if the bearing temperature
does not exceed 50 ºC. If the bearing temperature
during operation is above 50 ºC but below 80 ºC
and/or if there is danger of contamination, the oil
should be renewed about every six months.

properties and corrosion protection.
