Replacement Centrifugal Pump Drive Collar

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.

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
  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
