Mechanical seals.
Stationary part mounting: make sure that the bevel (or chamfer) and
the housing are absolutely clean and free from ragged edges and
traces of working. Damp the housing and the stationary gasket with
alcohol, glycerine or a compatible liquid. Press the stationary part into
the housing using a suitably covered stopper, mounted on the spindle
of a sensitive drill or small press.
Rotary part mounting: make sure that shaft is smooth, clean and free
from sharp edges. Polish the shaft if necessary with a fine abrasive
cloth (about 400 grains) even if it has been ground. After having
damped the shaft with alcohol, glycerine etc, mount the rotary part
turning the seal with a gentle motion in the direction to the winding of
the spring. Make sure that the two lapped faces come into contact. It
is harmful to put grease, oil, and other similar substances between
the faces of the seal which must be absolutely clean.
8. REASSEMBLY
General principle
This operation is carried out by reversing the disassembly
instructions.
In particular remember to:
a) replace worn out bearings with others of the same type
b) replace coupling blocks with others of the same type
c) check clearances between wear rings and impeller collar ( see tab.
5, 6, 7).
Mounting clearances pump HD-RB-RD
The figures indicates in tab.5-6-7 are minimum for new pumps. After
the prolonged usage of the pump, these figures could increase up to
50%.
The possibility to stand the increases indicated depends on the type
of liquid and working conditions, that is, delivery and suction
pressure. It is necessary to replace wear rings.
