Reassembly
(cont.)
11.
Lubricate the threads and install the
socket head screws (19) through the
rear plate (7). Torque the screws to
50% of recommended torque (see
table page 14) using a crossing
pattern. Check for free rotation of the
gears. If acceptable, continue to
torque to total recommended torque.
Again, check for free rotation of the
gears. See
Figure 14.
12.
Place a seal installation tool (lip seal
version only) (52) [item 41 on .05-2.4
cc/rev pumps] over the end of the
shaft.
Note: For Magnetically Coupled Pumps no
seal installation tool is required.
Insert the smaller O-Ring into the groove
on the adapter plate, using compatible
grease to retain the O-Ring into the
groove. Install the plate with the O-Ring
facing the pump body using the four
socket head screws and sealing washers.
Insert the square key onto the pump
shaft, then slide the inner magnet onto
the shaft. Refer to certified pump
assembly drawing to determine the
correct height/placement of the magnet.
Note:
This is critical to the pumps proper
operation. Secure the inner magnet by
tightening the setscrew upon the square
key. Place the larger O-Ring into the
exposed face of the adapter plate.
Lower the barrier cap into position over
the inner magnet. If applicable mount
the barrier cap by installing/tightening
the eight socket head screws.
Assembly is now complete.

Mechanical Seal Installation
a)
Snap the retaining ring (16) onto the
drive shaft. Install the mechanical
seal (13) onto the drive shaft with the
carbon end away from the front plate.
Take care when pressing the seal onto
the shaft.
The elastomer can be damaged
by the keyway or shaft edge.
b)
Align the set screws with the grooves
machined in the drive shaft and tighten
the set screws.
c)
Install the ceramic seat in the seal
housing (11) with the 0-ring of the
seat away from the mechanical seal.
14.
If your pump contains a double lip
seal (51) [item 13 on 4.5 & 9 cc/rev
pumps] push the seal to the rear of
the seal housing. Make sure there is
no gap between the seal and the
seal housing.
15.
Install the o-ring (33) into the recess
in the seal housing (11). If necessary,
use compatible grease to keep the
o-ring in place.
Note:
This ring may
already be in place if the pump was
previously assembled.
16.
Install the seal housing (11) over the
drive shaft (2). See
Figure 15.
17.
Lubricate the socket head screws and
install them (18) into the seal housing
(11). Tighten to the recommended
torque remembering to use a crossing
pattern.
18.
Install the square key (17) into the
drive shaft keyway.
