The ball bearing of the driving shaft is pressed into the housing.
A thorough cleaning is also possible without its dismantling.
When assembling the pump head it is important to fix the wing
screws (1, 2) and the nuts (8) only hand-tight.

The shaft seals (
5
and
6
, either red and green or both blue) are generally to be
replaced after 20,000 kg, at least once a year. For the exchange of all seals on the
pump head, we offer seal sets in different materials: Art. 307043 (food grade), Art.
307061 (chemical-resistant).
The pump head must never be operated in a dry state, i.e.
without product
. Without the lubricating effect of the product,
the synthetic gears would rub against one another and could
thereby be damaged or destroyed.
On the other hand, no lubrication is necessary with all other
parts of the filling equipment.
