Place the cartridge removal tool
ring over the shaft of one
cartridge assembly at a time.
Install two retaining screws to
attach the ring to the outer edge
of the carrier on the seal
assembly, and thread three
jacking screws into the removal
tool ring (
Fig 21 ) . As the jacking
screws are tightened into the ring
and against the pump housing,
the ring will pull the cartridge
assembly out of the seal bore.
Pull entire seal assembly up off
the lobe shaft. Repeat the
procedure for the other
mechanical seal assembly. Use
an even, slow pressure with the
jacking bolts to avoid bending the
assembly tool ring. Turn each
screw one or two turns at a time,
and rotate around the ring
increasing pressure with the
jacking screws (
Fig 22 ).
Note : If re-using a mechanical
seal assembly, the o-ring around
the outer circumference of the
assembly must be replaced.
These o-rings are part of the seal
assembly kit when ordered new.
