9.5.3 Reassembly of rotating element (Mechanical
seal version pump)
Procedure for rotor assembly for mechanical seal
pump is similar up to assembly of stuffing box
bush(11)
Reassembly of mechanical seal is as follows:
• Extreme cleanliness must be observed during ins-
tallation, and damage to the seal faces and moun-
ting rings must be avoided
• Place the adjusting ring of mechanical seal at its
pre marked position
• Place the grab screw(13) at its position on the
adjusting ring, but tight it yet
• The O-rings may be oiled to reduce friction, during
installation of the seal. EP-rubber O-rings should
not come into contact with oil or grease; In this
case lubrication with glycerine or water is recom-
mended.
• Never cover the sliding faces with a lubricant as
they must be assembled completely dry, clean and
dust-free.
• When pressing in stationery seals, make sure that
the pressure distribution is uniform. The O-ring
must be fitted using water or alcohol only.
• Crowned drive pins must be replaced whenever
the seal is dismantled. During insertion of the sta-
tionary seats, especially those of special carbon,
care must be taken to exert pressure evenly.
• Now check the distance of seal as shown in the
figure and adjust its value as per values given table
• For rest parts follow the above explained proce-
dure as per gland pack version pump
