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

CAUTION
The stub shaft has four sharp diagonal grooves in the end. Wear gloves to prevent injuries to hands
