Replacing the Liner in the Flex-I-Liner Pump
Note: When tightening bolts, apply even pressure. Tighten the bolts in a
sequence of: upper left — lower right — lower left — upper right.
Figure A-4: Replacing the
Flex-I-Liner
In Figure A-4, the bracket shown in the top photo
is that for close-coupled models. The bracket in the
other photos is for pedestal mount models. Other
components remain basically the same for all Vanton
Flex-I-Liner pumps.
To assemble:
Wipe Vanton Silicone oil on the ID of the liner
before assembling.
Grasp liner and block. Push the liner through
the back side of the block. Using your
finger, wipe the inside diameter of the liner
thoroughly with Vanton Silicone oil. Also
apply some of this oil to the rotor.
The object is to push the liner over the rotor
and metal boss (see arrow) of the back
plate.
As you can see from the photograph, the liner
has now seated itself over both the rotor
and metal boss of the back plate and the
flanges of the liner have seated in the recess
provided.
Once the liner is in place in the proper recess,
apply pressure to the block until the block
seats over the guide pins. Now install the
expansion ring and cover plate.
On occasion, it will be
necessary to replace a worn
liner. It is imperative that
this member be correctly
installed to insure maximum
longevity of the liner and
satisfactory future perfor-
mance and operation of the
pump.
