Centrifugal Pump Stub Shaft (MAR006)

Replacement Centrifugal Pump Stub Shaft

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
