Shaft's Examination Of The Vertical Turbine Pumps (VTP pumps)

Check the shafts Of The Vertical Turbine Pumps (VTP pumps) for straightness, pitting and wear. Remove all burrs or nicks. Shaft damage is usually best corrected by replacing the shaft.

The shaft Of The Vertical Turbine Pump must be straight to within 0.127 mm (0.005 in.) total indicator reading. The detail below shows the recommended method for checking shaft straightness. If the shaft is not straight, it must be straightened or replaced. If the deflection is gradual over a considerable length, the shaft can usually be straightened by supporting on two blocks straddling the crooked section and applying pressure to the high side to deflect the shaft in the opposite direction. If the shaft has a sharp crook (dog-leg), it is recommended that the shaft be replaced since the shaft will not always remain straight, even if satisfactorily straightened.

Even if the shaft Of The Vertical Turbine Pump is new or has been previously straightened, it is recommended that the shaft be re-checked at this point to ensure damage has not occurred in transit or handling.
