D. INSTALLING NEW SEAL ASSEMBLY (#4)
(Do not unwrap the new seal assembly until you
are ready to install. All parts of the assembly are packed in sequence of installation.)
1. To replace the seal assembly (4), perform the above operations under cleaning and remove pump
casing (5) by removing the three bolts (10B) holding the casing to the pump frame (10).
2. After cleaning all parts including pump shaft, begin the reassembly of the pump. Install seal grease
retainer (6) with the cavity portion of the seal facing outward. Rebolt the casing onto the pump
frame using the three cap screw (10B). Using a light oil lubricant (3 in 1), install the ceramic seat
with its neoprene holder into the seal recess making sure it is square with the shaft. Lubricate the
inside of the bellows assembly with a light oil and check to be sure the steel ring is stuck (glued) to
the end of the assembly. Slide the bellows assembly onto the shaft and push till the steel ring is
against the ceramic seat.
3. Install the seal spring on the hub of the impeller. After coating the threads on the pump shaft with
an anti-seize compound, install the impeller - seating it securely.
4. Utilizing the rubber O-Ring gasket (2) reinstall suction cover using the eight cover bolts (5B). At
this time, check to see that the pump runs freely. If the impeller rubs the cover plate, you do not
have the impeller tight on the shaft or the cover plate needs readjustment - see “impeller clearance”.
Tighten these bolts uniformly using 15 ft. pounds (165 kg/m) on the torque wrench.
5. After reinstalling the suction pipe assembly, lubricate and tighten the victaulic clamps. Service the
automatic lubricator.
