seal face is to be re-used, note which way
up it was fitted - seal faces are not
reversible.

To Re-assemble Mechanical Seals:

Note:

if refitting previously used seal faces

ensure that rotary and static faces are in
their original pairs.

Fit the seal face with the narrow face
track into the rotorcase. The seal face
with the wide face track should be
fitted into the rotor.

a) Fit the joint ring (83) to static primary seal
face and lubricate bore in the rotor case with
a suitable lubricant compatible with the
pumped fluid and the elastomer. Do not use
mineral-oil based lubricants on EPDM joints.

b) Align slots in seal face with ‘dogs’ of drive
plate in seal housing; a small cut-out is
provided so one drive dog can be seen (See
figure 14). Push each seal seat in straight;
when correctly fitted, seal seats should slide
freely against the resistance of their springs.

Undue pressure is not required or
recommended as seals are precision
components. Be sure not to damage the
joint ring (83), if difficulty is experienced put
the joint ring into the rotorcase bore then
push the seal seat into the bore.

Note:

if the rotorcase has been removed

(see section 6.10), static seal seats should
be inserted into the rotorcase, before
mounting the rotorcase onto the bearing
housing.

c) To fit seal seat to rotor (56 & 57), first
insert cup rubber (83) into the rotor (do not
lubricate), ensure alignment with drive pin.
(see figure 15). If PTFE trim is fitted, insert
the rubber washer first followed by the PTFE
sleeve. Note that the sleeve is slightly
tapered and will be easier to fit if the narrow
side is inserted first. Then lubricate outside
diameter of seal seat. (do not use mineral-oil
based lubricants on EPDM joints) Align drive
pin with one of the three slots in seal seat.
Engage the leading edge of the seal seat
into the cup rubber or PTFE sleeve. Push
down evenly until seal seat rests squarely
on bottom of seal bore in rotor. Do not
damage seat face. When correctly fitted,
