Assembly of the sleeve/Kingsbury bearing arrangement

If your pump is equipped with the rarely-supplied sleeve/Kingsbury bearing arrangement, refer

Post-assembly checks

Perform these checks after you assemble the pump, then continue with pump startup:

• Rotate the shaft by hand in order to make sure that it rotates easily and smoothly and that

there is no rubbing.

• Open the isolation valves and check the pump for leaks.
