The pump cover is fitted in the cover flange with the cover frame
(maximum outer diameter 825 mm).
Ensure that it is seated centrally.
To ensure secure and full-faced contact in the cover flange, a thin
layer of mortar should be applied. Fill the gap between the pump
cover and the cover flange with mortar or an equivalent material.
5.2.12. Final tasks
A flush connection can be installed for flushing the pressure pipe
using compressed air or water pressure. In addition, a vacuum relief
valve can be installed to protect against the pump chamber being
drained dry. Both of these components are available as accessories.

Wrap the thread on the flush connection with a standard sealant
(hemp, Teflon tape).

into one another depending on the required height.
Each thread connection must be sealed using a standard sealant
(hemp, Teflon tape).
