NOTICE:
When a cartridge mechanical seal is used, ensure that the set screws in the seal locking ring
are tightened and that the centering clips have been removed prior to startup. This prevents
seal or shaft sleeve damage by ensuring that the seal is properly installed and centered on the
sleeve.
6.8.5 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.
