After completing step 6, replace the
mechanical seal with the split collar
Final step is to remove the shaft coupling,
slide the seal up over the top and remove
the seal.
Remove fixing element and replace with
retraction devise. Thread the retraction
rod into the top of the shaft and secure
the nut against the cap
Release the connection from the
mechanical seal to the mixer shaft
Slowly tighten down on the
retraction nut pulling the shaft to the
top of the retraction cap
Pulling the shaft outward will engage the shut off plug.
SIDE ENTRY SHUT OFF PLUG
All mechanical seals provided with side entry mixers will come supplied with a set of their manufacturers'
instructions. If your side entry mixer seal starts leaking, please first refer to the seal instructions to review the
installation procedure, flush requirements and the manufacturers' trouble shooting guide.
The Cleveland Mixer shut off plug should only be activated as a last resort. It's always best to drain your
tank before removing the mechanical seal. If it is necessary to activate the plug in order to perform
maintenance on the seal, please take the following steps: (1) Turn the mixer off - You will need the shaft
retraction device and split collar that were provided with your mixer. (2) Remove the cap plate and fixing
element from the top of your mixers gear reducer. (3) Thread the retraction rod into the top of the mixing
shaft, then screw the nut down until it mates against the top of the retraction devise. (4) Release the
connection between the mechanical seal and shaft (typically set screws). (5) Tighten the nut on the
retraction devise, drawing the shaft out of the mixer towards you. Tighten the nut until the shaft pulls all
they way up to the retraction cap. (6) Very slowly! Start to release the mounting bolts for the mechanical
seal. If the plug is properly engaged, you shouldn't't get any more than a drip from the seal area. Remove
the bolts and slide the seal up to the shaft coupling. (7) Replace the seal with the split collar. (8)
Disconnect the removable coupling from the stub shaft flange in the center of the mixer shaft. (9) Slide the
mechanical seal up over the top of the seal and remove it to perform maintenance.
The shut off plug holds
water column pressure
and is only to be used as a
last resort. This plug is not
designed to be engaged
while the mixer is in
operation. Since the plug
sits on the inboard side of
the tank and can't be
inspected before use, use
extreme caution when
activating the plug. Do
not use this plug with
hazmats or dangerous
materials.
