From time to time, centrifugal pump mechanical components need to be replaced. TOP-FLO® centrifugal pump replacement parts are specifically designed to fit in the pumps of not only TOP-FLO® pumps but those of major pump suppliers. These components are rugged and will provide the necessary sealing conditions under a wide range of conditions.

STUB SHAFT ADJUSTMENT

1. Push the stub-shaft/impeller assembly
   toward the motor until the impeller strikes
   the front face of the backplate.
2. Move the stub-shaft away from the
   motor shaft to allow 1/16-inch maximum
   clearance between the rear face of the
   impeller and the front (inside) face of the
   backplate. (See Figure 22)
3. Tighten the two set screws on the stubshaft.
4. Remove the impeller retainer pin, impeller,and the backplate.
5. Slide the deflector (large diameter end
   first) onto the shaft until it seats in the
   shaft groove. (Figure 23)

NOTE: If the deflector cannot be forced on with the fingers, use a blunt tool to tap it

Drive Collar Adjustment

(Models TF-C114 through TF-C328)

1. Slide the seal drive collar onto the stub
   shaft as shown in Figure 24.
   Use the “A” dimension in the SEAL CHART
   to properly locate the drive collar on the
   stub shaft. Tighten the set screws to
   secure in place.
   NOTE: TF-C100 pump does not require drive
   collar.
2. Assemble the spring, seal cup, o-ring, and
   carbon seal, and install as a unit. Make
   sure the slot in the seal cup aligns with
   the pin on the shaft. (Figure 25) Gentle
   pressure on the o-ring will overcome
   resistance on the shaft.
   NOTE: Do not lubricate seals with any
   type of oil or grease, the seal faces will be
   lubricated by the product being pumped.
3. Assemble the gasket to the backplate.
   Install the backplate on the adapter. Make
   sure the seal cup slot is engaged with the
   pin on the drive collar. (Figure 25)
4. Rotate the backplate until the backplate
   pins engage the adapter pins. (Figure 25)
5. Rotate the shaft until the pin hole in the
   end is in a horizontal position. Insert the
   impeller pin, center it in the shaft end, and
   slide the impeller on the shaft.
   Hold the impeller tight against the stub
   shaft and rotate the shaft one-fourth turn
   until the impeller pin drops and secures the
   impeller. (Figure 26)
6. Place the casing over the impeller/
   backplate, close and tighten the clamp.
   (Figure 27)
7. Assemble the cascade water fitting, if
   included. Install the seal guard and tighten
   in place. Assemble the suction line and the
   discharge line to the casing.

NOTE: Check for strain or misalignment
of piping to the casing. Re-adjust the
casing ports and/or entire motor leveling as
necessary.
