6.5 Mechanical seal
Mount the mechanical seal as described in instructions of
seal manufacturer. The following points should be observed
when mounting mechanical seal :
Extreme care and cleanliness during assembly are the
essential prerequisites for the trouble free operation of the
mechanical seal.
The guard protecting the sealing faces should only be removed
only at the time of its fitment before assembly.
When the stationary seal ring has been inserted, check its
plane parallelism in relation to the discharge cover. The surface
of the shaft protection sleeve must be absolutely clean and
smooth and mounting edge of the sleeve must be chamfered.
Before final mounting in the pump, the rubbing faces of the
mechanical seal should be wetted with a drop or two of silicon
oil.
